That is impossible to answer in a forum like this. Things change so rapidly now that 5 years worth of changes means you have a lot to catch up on. The best place to start would be the ASP.NET website[^].

MVC is a big addition from 2011. You can still do WebForms (I am) but I think many would argue that MVC is the current way to go. Many use angular.js with MVC.
There is also the Entity Framework which you may have not used. I don't care for it but that may be because I don't use it properly.
Lambda and LINQ are probably new to you but are not ASP.Net specific but can be very useful.
If you didn't use jQuery that has become very big.
Good luck. Lots of good articles on this site.

What the others said. 
However, you should consider your own situation. WebForms still works fine. MVC is "cooler" but the transition from WebForms to MVC.NET is not easy.
If you used the AJAX Toolbox (or whatever it was called): it's been abandoned. Instead, MS chose to support the community behind jQuery.
So if you're just updating an existing site, perhaps you would get by simply making things nicer with jQuery. If on the other hand you would like to be more up to date, you should probably look into MVC.NET (and perhas some of the other things mentioned in these replies).
The problem with web development is that things move so fast that as soon as you get the hang of a language or framework, it's almost obsolete, especially if you're not working with web development on a daily basis.

In a vb.net 2010 web form application, I have a request from the user to be able to insert,update, and/or delete a row
in a single table. Thus I have the following questions to ask:
1. I am trying to decide if I should use a detailsviews, formview, gridview, and/or a different control for this purpose.
Thus would you tell me what control you would recommend and why you would recommend that particular control?
2. For the different options for insert, update, and delete, would I use the buttons that are on the control that you
recommend? If not would I use, new buttons that I place on the webform page?
3. For the control that you recommend that I use, should I place the sql 'embedded' in the sqldatasource, the control
you recommend and/or access the sql from a different location(vb.net code in a new location)?
Would you tell me , show me with pictures, and/or point to me to links (urls) that will show me how to accomplish
this

The traditional way of solving this is using a master/detail scenario:
1. Drag a gridview to the site, and bind it to the database's table. Rightclick it and choose to have a Select field shown.
2. Drag a details view to the page, and bind it as well. In its bidning window, you can graphically set a WHERE statement. Set your statement to Control, then chose your gridview as the control. Also click the advanced button to enable DELETE, UPDATE, and INSERT.
If done right, this means that when a user clicks the Select button for a particular row in the gridview, this row's data will appear in the detailsview. Then it can be updated or deleted, and more data can be inserted from the detailsview.
I don't know how much you know about binding to a database, but be sure you stay out of SQL injection trouble.
Note that searching for master/detail, gridview and detailsview you should be able to fond a lot of info on how to do this.
Good luck!

Hello. I have a side panel that is layed out like this:
<div class="panel panel-default">
<div class="panel-heading">
<h4>To Do</h4>
</div>
<ul class="list-group">
<asp:Repeater runat="server" ID="rptToDo">
<ItemTemplate>
<li class="list-group-item"><a href="Landing.aspx?Don=<%# Eval("ID") %>">X</a> <a href="Details.aspx?ID=<%# Eval("ID") %>"><%# Eval("ItemName") %></a></li>
</ItemTemplate>
</asp:Repeater>
<li class="list-group-item">
<asp:Panel runat="server" DefaultButton="btnAddToDo">
<input type="text" runat="server" id="txtAddToDo" class="form-control" placeholder="Add Item" />
<asp:Button runat="server" ID="btnAddToDo" Style="visibility: hidden;" OnClick="btnAddToDo_Click"></asp:Button>
</asp:Panel>
</li>
</ul>
</div>
Instead of having that text box at the bottom to add new records to, I'd like to put a good button or link of some sort to the right of my title , but still inside the gray area. I can't quite seem to get it to line up. Any help would be greatly appreciated.

It's looks like your using bootstrap with webforms. I haven't seen anybody do that yet. Interesting.
You would have to divide the title using the row and grid that bootstrap provides, because grids can only be childs of row.
<div class="panel-heading">
<div class="row">
<div class="col-sm-8">
<h4>To Do</h4>
</div>
<div class="col-sm-4">
<button class="btn btn-primary" type="button">Add +</button>
</div>
</div>
</div>

I gave it a shot over a month ago. Core is way different.
I think you have to use VS2015 to do core, and add the DotNetCore Development Kit to it.
Then you can open a new core project. I wasn't able to upgrade a project to core, but had to start a new project and build it piece by piece. I found that most of my classes were not compatible with core and had to be partially rewritten.
Plus you have to add Docker, so you can test the core and run it. Docker can be Mac, Linux and Windows based, doesn't matter.
After that, you just post the core to a server with Docker, and off you go!
I ended up postponing core development, to finish my project first, and then go to core. Maybe next year.
It's the way to go, but too much for me to chew on one time. I just adopted Node.js and Gulp, plus Sass for CSS and Bootstrap so I have my hands full at the moment.

I have an MSChart control on a web form that displays numerous line graphs. But I am unable to apply a text annotation. Nothing works thus far. I tried to add with VS 2013 community in both the designer and run-time code. Nothing shows up. But no errors are shown, either. Any suggestions?
Nothing from Microsoft was helpful. Or elsewhere in my search, although I noted lots of difficulties with this control.
|
|
|
|
|
what you want to do exactly with text annotation, MSCHART support shape, text, group annotation, which one you want to use ?
try with following simple snippet, see if it works
using System.Web.UI.DataVisualization.Charting;
...
LineAnnotation myLine = new LineAnnotation();
myLine.Name = "myLine";
myLine.X = 3;
myLine.Y = 3;
Chart1.Annotations.Add(myLine);

i have class User and my object have id
user.ID = 555
the user model have property
[ForeignKey("ID")]
public virtual IList<post> PostNames { get; set; }
i have class post :
public int IdUser { get; set; }
[ForeignKey("IdUser")]
public virtual User users { get; set; }
i get user.PostName - count = 0
and i know i have something in my database in post table.
What am I doing wrong ??
|
|
|
|
|
user.PostName - count = 0
Simple question. How can you substract a number from a string.
?????
|
|
|
|
|
Since you're using attributed mapping, you need to declare the type that you're mapping to. Your Post class is correct, but you need to change:
[ForeignKey("ID")]
public virtual IList PostNames { get; set; }
to
[ForeignKey("ID")]
public virtual ICollection<Post> PostNames { get; set; }

I am planning to automate a website (which is used to file tax). I think it is better to implement using asp.net. I am new to website automation. My questions are as follows,
1. How to make user to fill details in my asp page (User will enter details in my local server , and I will send those details to main website)
2. How to make user to enter captcha by showing him only image from main website in local page and later I will send that value to main website?
3. How to control child window from main window and vise versa using asp.net ?.

For this when user fills the details,you can make an HTTP POST to your main website.In this ,you can parse the parameters in your main website via an http post from your button click event handler when one clicks on the button after entering the details.

Hello,
I have a form in which users can select "yes-full time", "yes-part time", "No" or "Retired"
In the code behind, I am trying to turn off validation for three textboxes and one radiobuttonlist if the user selects "No" or "Retired"

Hello,
Thanks for the quick reply.
I am trying to have three textboxes and one radiobuttonlist have its requiredfieldvalidators disabled based on a previous radiobuttonlist.
My code behind is as follows:
------------
protected void rbCurrentlyEmployed_SelectedIndexChanged(object sender, EventArgs e)
{
if (rbCurrentlyEmployed.SelectedValue == "No" || rbCurrentlyEmployed.SelectedValue == "Retired" )
((RequiredFieldValidator)txtEmployer.FindControl("RFV_Employment_Employer")).Enabled = false;
((RequiredFieldValidator)txtJobTitle.FindControl("RFV_Employment_JobTitle")).Enabled = false;
((RequiredFieldValidator)txtWorkPhone.FindControl("RFV_Employment_WorkPhone")).Enabled = false;
((RequiredFieldValidator)rbgrantsmatchingfunds.FindControl("RFV_Employment_MatchingFunds")).Enabled = false;
else
{
((RequiredFieldValidator)txtEmployer.FindControl("RFV_Employment_Employer")).Enabled = true;
((RequiredFieldValidator)txtJobTitle.FindControl("RFV_Employment_JobTitle")).Enabled = true;
((RequiredFieldValidator)txtWorkPhone.FindControl("RFV_Employment_WorkPhone")).Enabled = true;
((RequiredFieldValidator)rbgrantsmatchingfunds.FindControl("RFV_Employment_MatchingFunds")).Enabled = true;
}
}
-----------------
I seem to be getting an error in the syntax of the 'else' statement.
ANY help would be greatly appreciated

You're missing the braces around the content of the if branch. As a result, only the first statement is considered part of the if branch - as if you had written:
if (rbCurrentlyEmployed.SelectedValue == "No" || rbCurrentlyEmployed.SelectedValue == "Retired" )
{
((RequiredFieldValidator)txtEmployer.FindControl("RFV_Employment_Employer")).Enabled = false;
}
((RequiredFieldValidator)txtJobTitle.FindControl("RFV_Employment_JobTitle")).Enabled = false;
((RequiredFieldValidator)txtWorkPhone.FindControl("RFV_Employment_WorkPhone")).Enabled = false;
((RequiredFieldValidator)rbgrantsmatchingfunds.FindControl("RFV_Employment_MatchingFunds")).Enabled = false;
else
{
((RequiredFieldValidator)txtEmployer.FindControl("RFV_Employment_Employer")).Enabled = true;
((RequiredFieldValidator)txtJobTitle.FindControl("RFV_Employment_JobTitle")).Enabled = true;
((RequiredFieldValidator)txtWorkPhone.FindControl("RFV_Employment_WorkPhone")).Enabled = true;
((RequiredFieldValidator)rbgrantsmatchingfunds.FindControl("RFV_Employment_MatchingFunds")).Enabled = true;
}
Add the braces, and the syntax error will go away:
if (rbCurrentlyEmployed.SelectedValue == "No" || rbCurrentlyEmployed.SelectedValue == "Retired" )
{
((RequiredFieldValidator)txtEmployer.FindControl("RFV_Employment_Employer")).Enabled = false;
((RequiredFieldValidator)txtJobTitle.FindControl("RFV_Employment_JobTitle")).Enabled = false;
((RequiredFieldValidator)txtWorkPhone.FindControl("RFV_Employment_WorkPhone")).Enabled = false;
((RequiredFieldValidator)rbgrantsmatchingfunds.FindControl("RFV_Employment_MatchingFunds")).Enabled = false;
}
else
{
((RequiredFieldValidator)txtEmployer.FindControl("RFV_Employment_Employer")).Enabled = true;
((RequiredFieldValidator)txtJobTitle.FindControl("RFV_Employment_JobTitle")).Enabled = true;
((RequiredFieldValidator)txtWorkPhone.FindControl("RFV_Employment_WorkPhone")).Enabled = true;
((RequiredFieldValidator)rbgrantsmatchingfunds.FindControl("RFV_Employment_MatchingFunds")).Enabled = true;
}
