Where is your menu coming from ? There's no menu built into ASP.NET AFAIK.

You can make changes to what appears in the menu at runtime by manipulating the nodes in the OnMenuItemDataBound event, however persisting changes to the web.sitemap file is not so easy as this file is cached and the changes will not be visible until the application restarts.

Use a Regular Expression Validator control and specify a regular expression that checks whether the input corresponds to the format of a valid email address. There are plenty of examples available of you search Google[^].

Sounds like you have css issues. Try running it on FireFox and see how bad it looks.
Seriously, getting your styling right for all browsers is a major undertaking.

Visual Studio Generates style tags when you drag drop any control, so just remove the style tags which are generated by the IDE.
Hope this will help you out

I have a template Header as below
<asp:templatefield headertext="Exclude Language">
...
</asp:templatefield>
How can I change the header text on Runtime. I want to do it with C#

Pavas

Use this line of code where you want to change the HeaderText
"Cell[0]" where0 is the index of the cell
GridView1.HeaderRow.Cells[0].Text = "Usman";

hi all
can anyone tell me what type of styles are used to show the color as glowing(like in yahoo front page)and also the color codes of the colors used in the yahoo front page.

If the color changes, it's being done with javascript, no style or color changes by itself.
