u can validate once the user has typed the value and tabs / focus out of the textbox using onblur event. write a function in javascript to which u pass the textbox and fetch the value inside, validate and return if it contains other than numeric values.
u can add this fn using attributes.add method to the textbox.

function NumberOnly()<br />
{<br />
<br />
if ((window.event.keyCode >= 48 && window.event.keyCode <=57)) <br />
return true;<br />
else<br />
<br />
return false;<br />
<br />
}
And use
<asp:textbox id="txtNo" runat="server" width="170px" onkeypress="javascript:return NumberOnly()></asp:TextBox></code></pre>

What about backspace, delete, arrow keys, tab and all the other control keys that you should allow?

Strictly speaking, the subject does say "restrict text box to take only numbers". Don't introduce feature creep at this late stage.

I have a pop up page and on it there is a button im using to save data, but after saving i want to refresh the main page(which is working fine) but after that i want to close the pop up page as well(which aint happening-the problem). My problem is if i have both of these statements/functions under one control only the first one works. im running these lines from c# under the click event of the save button.
Does anyone know what the problem is.
string scriptString2 = " window.opener.document.forms(0).submit(); ";
if (!Page.ClientScript.IsClientScriptBlockRegistered(scriptString2))
{
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "submitScript", scriptString2);
}
string scriptString = " window.close(); ";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "submitScript", scriptString);

Submit both the scripts at once. You can concatenate the secound script to scriptString2.

How do i force a page postpage using a button. say i want to make a control on a page invisible when i click a button- note setting to invisible requires a postback on the page
Thank you

server side buttons generally post backs... if you have made that button inside one updatepanel use PostBackTrigger.
