To the best of my knowledge, No.
for max length, that's an HTML5 thing.
<input type="number" name="digits" maxlength="2">
But there are some caveats to using this. I don't think 0 is a number, more like 1+.
In MVC, you would add an attribute to the form model, and the validator would check it.
Or in JQuery.Validate, you would write a rule.

I understand, if it is Kendo control like this, and I want to add or remove validations to it, how can I do?
@Html.Kendo().TextBoxFor(model => model.Code).Name("txtForCode").HtmlAttributes(new { autocomplete = "off", id = "idTxtForCode" })
I want to add or remove validation conditions for this textbox dynamically, is there any way to do it using jquery?

I'm not sure if JQuery can change the input type from text to number. But you can add max, min, length.
I think browsers have locked input type, so you can't change a password to clear view.

No I don't want to change input type from text to number but what I want is, if text is typed when its value is supposed to be number, it shouldn't take that value, I mean no matter how many characters user types, it shouldn't display or take it, when it is supposed to be characters, the numbers or numerical values shouldn't be taken as input in the textbox. And the number of characters or numbers should be limited depending upon the conditions in JavaScript function.
Below is the example for JavaScript function:
function GetLookupTableValue(e)
{
var noCodeFilter = containsAny($("#drpLookup").data("kendoDropDownList").text(), ['Address Type', 'Gender', 'NPI Status', 'Rendering Provider Status', 'Rendering Provider Classification']);
if (noCodeFilter)
{
var url = '../Admin/GetLookupTableNoCode';
$("#divLookupTable").load(url, { LookupTableId: $("#drpLookup").data("kendoDropDownList").value() });
}
else
{
var url = '../Admin/GetLookupTableCode';
$("#divLookupTable").load(url, { LookupTableId: $("#drpLookup").data("kendoDropDownList").value() });
$("#idTxtForCode").addClass('del'); //.removeClass('add')
}
}

Hi,
Yes I did in the below way
<script><br />
if (1 == 1)
{
$('#idTxtForCode').addClass("allownumericwithoutdecimal");
}
<pre>
$(".allownumericwithoutdecimal").on("keypress keyup blur", function (event)
{<br />
$(this).val($(this).val().replace(/[^\d].+/, ""));
if ((event.which < 48 || event.which > 57))
{
event.preventDefault();
}
});
in the following form, it is working fine for the character values like its not inputting the character values when I type in, but when I enter one integer value it is working fine but when I enter second value, its removing all the values I entered making the textbox blank, I am not understanding why is it doing that way.
My form is as below:
@model XXXXX.Provider.Models.LookupTable
@{
ViewBag.Title = "EditLookup";
}
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<pre>
<div class="k-edit-form-container">
<div class="editor-field" style="display:none;">
@Html.Kendo().TextBoxFor(model => model.LookupTableId).HtmlAttributes(new { id = "idLookupTableId" })<br />
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Code)
</div>
<div class="editor-field">
@Html.Kendo().TextBoxFor(model => model.Code).Name("txtForCode").HtmlAttributes(new { autocomplete = "off", id = "idTxtForCode" })
@*.HtmlAttributes(
new { style = "width:250px", type = "text", size = "5", id = "txtLENum", required = "required", maxlength = "5", pattern = "[a-zA-z0-9]{5}", validationmessage = "Enter only 5 numerics for {0}" })*@
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Description)
</div>
<div class="editor-field">
@Html.Kendo().TextBoxFor(model => model.Description).HtmlAttributes(new { autocomplete = "off" })
</div>
<div class="editor-label" style="display:none;">
@Html.LabelFor(model => model.CreatedBy)
</div>
<div class="editor-field" style="display:none;">
@Html.Kendo().TextBoxFor(model => model.CreatedBy)
</div>
<div class="editor-label" style="display:none;">
@Html.LabelFor(model => model.CreatedDate)
</div>
<div class="editor-field" style="display:none;">
@Html.Kendo().DatePickerFor(model => model.CreatedDate)
</div>
<div class="editor-label" style="display:none;">
@Html.LabelFor(model => model.ModifiedBy)
</div>
<div class="editor-field" style="display:none;">
@Html.Kendo().TextBoxFor(model => model.ModifiedBy)
</div>
<div class="editor-label" style="display:none;">
@Html.LabelFor(model => model.ModifiedDate)
</div>
<div class="editor-field" style="display:none;">
@Html.Kendo().DatePickerFor(model => model.ModifiedDate)
</div>
<div class="editor-label" style="display:none;">
@Html.LabelFor(model => model.IsValid)
</div>
<div class="editor-field" style="display:none;">
@Html.Kendo().CheckBoxFor(model => model.IsValid)
</div>
}
And instead of doing the above function why is giving me error?
$(".allownumericwithoutdecimal").on("keypress keyup blur", function (event)
{
var charCode = (event.which) ? event.which : event.keyCode;
if(charCode > 31 && (charCode < 48 || charCode > 57))
{
event.preventDefault();
}
});
Thanks,
Abdul Aleem

I had to dig this up. I wrote this several years ago
function isNumberKey(evt) {
var charCode = evt.which ? evt.which : event.keyCode;
if (charCode !== 46 && charCode > 31 && (charCode < 48 || charCode > 57))
return false;
return true;
}
@Html.TextBoxFor(m => m.Order_Select_Product_Qty, new { @class = "form-control", min = "1", max = "1000", Value = "1", type = "number", pattern = "[0-9]*", inputmode = "numeric", onkeypress = "return isNumberKey(event);" })

But I could able to find the reason why its not working, because the textbox is in a partial view and as I am loading the partial view multiple times those functions are getting loaded multiple times, even if I use within document.ready, still it would be added multiple times. As I am opening the partial view as in the below Kendo grid popup , is there any way to clean this up once I close the popup or finish my task?
Page: Lookup2
<div id="datalist">
@(Html.Kendo().Grid<DHCS.BH.Provider.Models.LookupTable>()
.Name("LookupGrid")
.EnableCustomBinding(true)
.AutoBind(true)
.Columns(columns =>
{
columns.Bound(p => p.Id).Hidden();
columns.Bound(p => p.Code).Width(200);
columns.Bound(p => p.Description).Width(290);
columns.Bound(p => p.CreatedDate).ClientTemplate("#=DateFormat(CreatedDate)#").Width(130);
columns.Bound(p => p.CreatedBy).Width(150);
columns.Bound(p => p.ModifiedDate).ClientTemplate("#=DateFormat(ModifiedDate)#").Width(140); ;
columns.Bound(p => p.ModifiedBy).Width(150);
columns.Bound(p => p.IsValid).Width(100).Hidden();
////columns.Command(command => { command.Custom("View").Click("ViewLookupTableValues").HtmlAttributes(new { @class = "k-primary" }); }).Width(100);
columns.Command(command => { command.Edit(); command.Destroy(); }).Width(200);
columns.Bound(p => p.LookupTableId).Hidden();
columns.Bound(p => p.ForeignKeyId).Hidden();
})
.ToolBar(toolbar =>
{
toolbar.Create().Text("Add New");//.HtmlAttributes(new { @class = "k-button" });
})//.HtmlAttributes(new { @class = "btn btn-primary" })
.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("_EditLookupCode"))
.Pageable()
.Sortable()
.Scrollable()
.Resizable(resize => resize.Columns(true))
.Filterable(x => x.Extra(false).Operators(O => O.ForString(str => str.Clear().StartsWith("Starts With"))))
.HtmlAttributes(new { style = "height:550px;" })
<pre>
.Events(events => events.Edit("LookupPopUpTitle"))
.DataSource(ds => ds
.Ajax()
.PageSize(10)
.Model(model => { model.Id(p => p.Id); })
.Read(read => read.Action("GetLookupValues", "Admin").Data("GetLookupTableId"))
.Create(update => update.Action("AddLookupRecord", "Admin").Data("GetLookupTableId")).Events(e => e.Sync("GetLookupTableValue1"))
//.Create(c => c.)
.Update(update => update.Action("UpdateLookupRecord", "Admin"))//.Data("GetLookupTableId"))
.Destroy(update => update.Action("DeleteLookupRecordById", "Admin"))
)
)
Even this grid is also within Partial View and I am loading it by using javascript funtion as below:
Page name: lookup 1
var url = '../Admin/GetLookupTableCode';
$("#divLookupTable").load(url, { LookupTableId: $("#drpLookup").data("kendoDropDownList").value() });
seems that I need to clean these partial views once I am done with them, as the problem is happening in the Add New call of the Page: Lookup 2, I would need to clean it up it seems, (how did I come to this conclusion, because first time it worked properly then second time onward it started giving me problems), any help would be very very helpful my friend, I spent lot of time on it, thanks for understanding my friend.
or in simple, is there any way I can remove the document.ready that has been loaded and reload it again with the partial view load, because the if condition and function calls are not working directly if I am writing under script task like
if (x==y)
alert("Hi");
But works only once if I write the following within partial view cshtml
document.ready()(function({
if (x==y)
alert("Hi");
});
But this doesn't work, more than once maybe because it can not work if document.ready is loaded multiple times.
Thanks,
Abdul Aleem

I'm sort of confused now on what your trying to create. remember I'm not there with ya and can't see what your doing.
Document Ready is a signal indicating that the Dom is loaded, so you can execute client script automatically. Don't use it.
And write a new external file, don't write it on the view page.
I would imagine that your Document Ready would be empty, and when the dropdown changes value, then you call a independent JQuery Ajax function to load the partial view by calling a controller action and returning the HTML generated by the server.
You can wrap the partial view HTML in a wrapper with a known ID, so you can call $("#KnownID").empty() to dump the partial view and $("#KnownID").html(data.partialview); to load the partial view.

Yeah I can understand my friend, you are confused, and yes you are not with me to see and help directly, even doing this much is really really great - I think you live in LA, CA right? If you are travelling to Sacramento, CA, please please let me know I want to personally see you, meet you and thank you, if you don't mind give you a treat.
Because even helping this much to a person who you speak just online is great - you must be a great human.
And your imagination is right, there are two partial views I am loading, 1 I am loading with load method:
var url = '../Admin/GetLookupTableCode';
$("#divLookupTable").load(url, { LookupTableId: $("#drpLookup").data("kendoDropDownList").value() });
the other one I am loading with with Kendo popup:
.ToolBar(toolbar =>
{
toolbar.Create().Text("Add New");//.HtmlAttributes(new { @class = "k-button" });
})//.HtmlAttributes(new { @class = "btn btn-primary" })
.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("_EditLookupCode"))
Somehow I need to clean these two Partial Views once I am done, , can you please let me know the syntax for how to wrap partial view within some known id and empty partial view after I am done or finished with it?
The first Popup that's being loaded with load method on the div "divLookupTable" just calls url with action method, loads within the same page, that contains a Kendo grid, which when clicked on Add New or Edit on a row, opens up partial view _EditLookupCode as a popup.
But if I have written the document.ready only in the main page and tried to retrieve the TextBox, that is placed in the Popup (of Partial View _EditLookupCode), I am not able to retrieve, if I kept my document.ready in the _EditLookupCode partial view itself, its giving me error after second run, but if I write any if else conditions withing this _EditLookupCode.cshtml partial view within script tasks, still its not executing.
Is there anyway I can retrieve the elements that are there on the _EditLookupCode.cshtml, note that this is the second partial view which opens up from click of a button on another partial view.
Thanks,
Abdul Aleem

I haven't been up in Northern California in a long time. I stopped there for gas on the way on from Seattle about 10 years ago.
I'd be glad to meet you!
I'm been following this on the thought that it's a single page application with no http postbacks.
just pure manipulation of the DOM using client script. I suspect the postbacks are messing you up and confusing me.
I can't write anything, and I think you have a flawed design in general and need to step back and rethink it.
I beginning to think that your trying to postback the Kendo Grid, or a textbox value depending on the dropdown selection.
You should be able to have both objects available, and just show and hide them. Then on the postback, check the dropdown value in the controller or page postback event, and use a switch to execute updating the selected section.

Thanks my friend, sure we will try to meet for a lunch or something when you are travelling here or when I am travelling in Orange County.
It seems there is something problem in it, I am very basic in jQuery and client script.

hi Buddy,
I could able to do it by writing a function in the main page and calling that function multiple times in the popup whenever it loads, but another thing remaining is just putting numerical and text restrictions on the page depending upon the drop down selection.
Yes you were right I had flaw that I was trying to create function in the popup as it loads multiple times, we can't have function definition multiple times hence it was throwing error.
thanks a lot buddy.
Thanks,

Well I started doing some optimization such as image compression and cache headers, and stumbled upon the fact that I just can't drop these files into the root of wwwroot and expect them to serve. I get the 404 error and redirect to my 404 page.
I ran across one article that says I need middleware for the favicon.
I'm not sure about the site map and robots.txt.
I keep searching but perhaps I'm just not asking the right question, can't find anything.

I got it now.
I used the Startup.cs, UseStaticFiles and polished it more for Favicon.ico and Google Verification, ServeUnknownFileTypes
Then added a Package and controller for Sitemap, and wrote a controller action for Robots.txt.
I added this, not sure if I need it, most likely not.
app.UseFileServer(new FileServerOptions() {
EnableDefaultFiles = false

First check that i is set to the correct id value you expect.
Second why not get the entire record in the first query and test if the object is null.

MessageBox.Show will not work in an ASP.NET application. It might appear to work when you're debugging in Visual Studio; but that's only because the server and client are the same computer in that scenario. As soon as you deploy your code to a real server, it will break.
In the best-case scenario, you'll get an exception telling you that you can't display a messagebox from a non-interactive application. In the worst-case, the message will appear on the server, where nobody will ever see it, and your code will hang waiting for a response.

Well I was going to post a question on Reactjs and why it converted my model class to lowercase which crashed the page. Talk about a head scratchier, trying to figure out if my packages are not setup right, an error in my JSX file, or Bable.
<script>ReactDOM.hydrate(React.createElement(CommentBox, {"initialData":[{"id":1,"author":"Daniel Lo Nigro","text":"Hello ReactJS.NET World!"},{"id":2,"author":"Pete Hunt","text":"This is one comment"},{"id":3,"author":"Jordan Walke","text":"This is *another* comment"}],"url":"/comments","submitUrl":"/comments/new","pollInterval":2000}), document.getElementById("react_0HLF3D2L0PCGB"));
But I figured it out

</script>
Just had to change the NewtonSoft ContractResolver From CamelCase to DefaultContractResolver in in Startup.cs.
At any rate, I have just completed porting my app over, and it was really hard to learn all of these new concepts, while expanding on subjects I never bothered to look deeper into like HttpContext, Session and Cookie.
But what I ended up with is a very clean project with no clutter that is coded without evil bad habits.
I dumped some of the Razor elements for just tags and asp-....., which I might go farther with. Not sure if this is the death or Razor for me, or if I still need to use it.
I'm very happy with .Net Core 2.1 and I dig it. Seems really fast. Now I need to figure out what middleware is, and learn more about the details. Hopefully I server this up on my production web server.
I feel good about this!

How to use angular along with ASP.NET mvc project?
Aren't Angular and ASP.NET MVC mutually exclusive?
I mean angular is totally different than asp.net mvc,
here(asp.net) code executes on server and in another(angular) js code executes on client side.
asp.net view and angular view are totally different
