Simple ASP/ASP.NET question. Getting a value from an HTML text box

I have this in my ASPX page:

<input id="MY_LAST_FOCUS" name="MY_LAST_FOCUS" type="text" runat="server" />

In the Form Load of my VB.NET code behind I have this:

Dim s as String = Request("MY_LAST_FOCUS")

Why is s always empty even though the MY_LAST_FOCUS HTML text box has text in it?

Its empty because you seem to be grabbing from the Request object for something named what your input is, and not grabbing the contents of your input itself.

I agree with Jack, but if you want to keep it a plain old HTML input box, you could just get the value of it:

Dim s As String = MY_LAST_FOCUS.Value

This only works as long as you keep runat="server" on it though. And like Jack points out, you probably should just use an ASP.NET TextBox control instead.

Dim s as String = Request.Form(MY_LAST_FOCUS)

This works for me.

I agree with @Jack Marchetti though.

If you want to access directly from the request, then use the UniqueID of the control:

Request.Form[MY_LAST_FOCUS.UniqueID]

Why don't you use:

<asp:Textbox ID="MY_LAST_FOCUS" runat="server">

then in your code_behind you can access:

Dim s as String = MY_LAST_FOCUS.Text
