i want to ask about the post by ashish chaudhary, in which we are suppose to fill the datagrid and then export it to excel file. I am using the same code, but i am getting the error in the given below line.
"string Path = "D:\\DataListWebsite\\myexcelfile_" + DateTime.Now.ToString() + "_" + DateTime.Now.Month.ToString() + ".xls";
All the code is as it is..... No issue . Please help....
|
|
|
|
|
Should the quote in front of string be there?
|
|
|
|
|
Why not ask ashish chaudhary (whoever he/she is)?

First of all, like Richard said: Ask this question under their post because do not know the context that you are working under. So we cannot help you.
Finally, if the problem is with saving only you need to understand that you cannot have special symbols in filenames (":" for instance). DataTime object will hold these, for the time values, which causes the problem. That can be one of the problems here.

By writing a lot of code. Where are you stuck? I'm sure there are examples online you could follow. Ask Google, she knows everything.

I want to show required validator when Contract is selected on this toggle.
<label for="exampleNASAControlNumber">Is this a Contract or Solicitation?:</label>
<label class="switch2">
<input class="switch-input2" type="checkbox" id="contractselection" name="contractselection" runat="server"/>
</label>
The validation should work for this only when contract is selected:
<label for="exampleStartDate" style="position:relative; right:17px;">Contract Start Period:<span style="color:red">*</span>:</label>
<div class="bootstrap-iso">
<div class="row">
<div class=" zero-padding-left">
<div class="input-group">
<div class="input-group-addon">
</div>
<input class="form-control" id="contractstartdate" name="contractstartdate" runat="server" placeholder="MM/DD/YYYY" type="text" style="width:240px;"/>
</div>
<asp:RequiredFieldValidator ID="RequiredFieldValidator6" ForeColor="Red" runat="server" ControlToValidate ="contractstartdate" ErrorMessage="Please select a Contract Start Period">
</asp:RequiredFieldValidator>
and disabled for this validator:
<label for="exampleStartDate" style="position:relative; right:15px;">Solicitation Start Period:<span style="color:red">*</span>:</label>
<%----%>
<div class="bootstrap-iso">
<div class="input-group" style="position:relative; right:15px; width:296px;">
<div class="input-group-addon">
</div>
<input class="form-control" id="solicitationstartdate" name="solicitationstartdate" runat="server" placeholder="MM/DD/YYYY" type="text"/>
</div>
<asp:RequiredFieldValidator ID="RequiredFieldValidator8" ForeColor="Red" runat="server" ControlToValidate ="solicitationstartdate" ErrorMessage="Please select a Solicitation Start Period">
</asp:RequiredFieldValidator>
The reverse of this when Solicitation is selected, the Contract Start Date validator should be disable and the Solicitation Start Date validator is enabled.
How do I do this?

I did it using manual validation and jQuery.Validator.js. for MVC
I never used the validator for WebForms.
But I would remove your validators and go manual.
I wrote a jquery script called load_cc_validator and called it when I toggled the form module in jquery.
So I wrote the HTML in Razor and manually assigned the values
<h4>Card information</h4>
<div class="form-group">
@Html.Label("Edit_CC_FirstName", "First name on card", new { @class = "control-label" })
<div class="input-group">
@Html.TextBox("Edit_CC_FirstName", "", new { @class = "form-control", data_val = "true", data_val_required = "Card first name required", placeholder = "First name on card" })
@Html.ValidationMessage("Edit_CC_FirstName", new { @class = "field-validation-valid", data_valmsg_replace = "true" })
</div>
</div>
<div class="cxo-paymentForms-creditCard-submit right">
@Html.Hidden("Edit_CC_PaymentID")
@Html.Hidden("Edit_CC_Brand")
<button class="btn btn-default btn-lg mobile" type="button" onclick="return editPayment_cancel()">Cancel</button>
<button class="btn checkout pull-right mobile" type="button" onclick="return submit_eCC()">Save</button>
</div>
submit_eCC is just a $ajax call to the controller to update the database, and has nothing to do with validation.
editPayment_cancel just clears the form and hides the form module.
Since I'm using $ajax, I set the Submit Form Handler to false to not submit a post back of the form.
And then wrote the script and called it. This example reflects the whole module, and would take too much time to condense
function load_eCC_validate() {
var $cC_form = $("#Edit_CreditCard"),
$cC_location = $("#Edit_CC_LocationName"),
$cC_fName = $("#Edit_CC_FirstName"),
$cC_lName = $("#Edit_CC_LastName"),
$cC_code = $("#Edit_CC_Code"),
$cC_phone = $("#Edit_CC_Phone");
$bA_streetAddress1 = $("#Edit_CC_StreetAddress1"),
$bA_city = $("#Edit_CC_City"),
$bA_stateCode = $("#Edit_CC_StateCode"),
$bA_postalCode = $("#Edit_CC_PostalCode"),
$bA_countryCode = $("#Edit_CC_CountryCode");
$cC_form.validate({<br />
errorClass: 'form-control input-validation-error',
validClass: 'form-control',
errorElement: 'span',
success: "valid",
rules: {
"Edit_CC_LocationName": {
required: true
},
"Edit_CC_FirstName": {
required: true
},
"Edit_CC_LastName": {
required: true
},
"Edit_CC_ExpMonth": {
required: true,
valueNotEquals: ""
},
"Edit_CC_ExpYear": {
required: true,
valueNotEquals: ""
},
"#Edit_CC_Code": {
required: true
},
"Edit_CC_Phone": {
required: true,
phoneUS: true
},
"Edit_CC_StreetAddress1": {
required: true
},
"Edit_CC_City": {
required: true
},
"Edit_CC_StateCode": {
required: true
},
"Edit_CC_PostalCode": {
required: true,
zipcodeUS: true
},
"Edit_CC_CountryCode": {
required: true
}
},
messages: {
"Edit_CC_LocationName": "Unique name is required",
"Edit_CC_FirstName": "Card first name required",
"Edit_CC_LastName": "Card last name required",
"Edit_CC_Code": "Card Security code required",
"Edit_CC_ExpMonth": "Card exp month required",
"Edit_CC_ExpYear": "Card exp year required",
"Edit_CC_Phone": "Phone number required",
"Edit_CC_StreetAddress1": "Billing street address required",
"Edit_CC_City": "Billing city required",
"Edit_CC_StateCode": "Please select your state",
"Edit_CC_PostalCode": "Postal/zip code required",
"Edit_CC_CountryCode": "Please select your country"
},
submitHandler: function (form) {
return false;<br />
},
invalidHandler: function (event, validator) {
var errors = validator.numberOfInvalids();<br />
},
errorPlacement: function (error, element) {
$(element).parent().next('span').html(error);
}
});
}
This works exactly like assigning required to the model, only I didn't assign required to the model.
Hope this makes sense to you, can't really explain it in more detail. But the HTML I posted is exactly what is needed to make it work.
Note, you may be able to disable validation using jquery by changing one of the attr in the validator. You have to look at the HTML that is generated to see which attr to change in the elements.

Perhaps Specifying Validation Groups may be what you need?

ValidationGroup won't work. I only have one button on my form.

Is it possible to call a javascript function in a cshtml, in the @{} section, and the javascript function is defined in the script section of the cshtml.
Thanks
|
|
|
|
|
No, your cshtml is compiled and executed as .net code on the server, the result is that it generates html, that html is then sent to the client browser to be executed and the client browser can interpret and execute javascript. So you can't run javascript in your views as the javascript doesn't yet technically exist.
|
|
|
|
|
I have a list passed on to the view from the controller through a viewbag. so if the viewbag has the list, then execute a javascript function that is defined in the script section of the page. what is the other option?
|
|
|
|
|
<script type="text/javascript">
function myFunc() {
alert('Hello');
}
</script>
@if (ViewBag.MyList != null)
{
<script>myFunc();</script>
}
Note the order is important, js is interpreted in order so you can't call functions that have not yet been defined.

Hi,
I created a mvc web project with scaffolding that displays well in the Index page. When I edit, I do not want any of the fields in the edit page to edit. Instead, I added a textbox whose value I calculate and save the rest of the fields to the database. I cannot get this to work, as the model in the HttpPost is null. Please help.
Thanks

Have you looked into any tutorials about doing CRUD in ASP.NET MVC? You should be able get more references in the web. The idea is to send back the model to your action method if your action requires the model on POST request. I would really recommend you to read the basics on how MVC arch works before jumping into the limbo.
Here's an article that may help you understand the basic of ASP.NET MVC: ASP.NET MVC 5: Building Your First Web Application - Part 1[^]

There's a problem somewhere in your secret code. You should fix that.
If you want someone else to help you fix it, then you'll need to share the relevant parts of your code.

Did you wrap the textboxes and submit button in a form tag or element?, so the input elements post back to the controller.
