Dear All

I added a textbox control in my ABC.aspx, the code is like this

<input id="txtSessionKey" name="txtSessionKey" type="text" value=""/>

Then I tried to give it a value in the ABC,aspx.cs, the code is

txtSessionKey.Value = "123";

However, when I compiled, I got this error:

Error 2 The name 'txtSessionKey' does not exist in the current context

I am quite new in .NET area.

please help me if anyone has solved this problem before.

Thank you

Hi
if you write like below it only availabe on client browser means u can call this control by using client script(javascript/jQuery) but not in C# .cs file

but if you want to access the control from C# .cs file u have to use runat attribute . if you runat="SERVER"

thanks

In order for any item in your aspx file to be visible to the code behind you have to tag it with runat="server" and recompile. It should be all you need to do.
