You can look at the code below. Hope this will solve your problem.

<br />
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > <br />
<br />
<html><br />
  <head><br />
    <title>Test</title><br />
    <meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1"><br />
    <meta name="CODE_LANGUAGE" Content="C#"><br />
    <meta name=vs_defaultClientScript content="JavaScript"><br />
    <meta name=vs_targetSchema content="http://schemas.microsoft.com/intellisense/ie5"><br />
		<script type="text/javascript"><br />
			<!--<br />
			function setValue()<br />
			{<br />
				document.getElementById("lblName").innerHTML = document.getElementById("txtName").value;<br />
			}<br />
			//--><br />
		</script><br />
  </head><br />
  <body><br />
	<br />
    <form id="Form1" method="post" runat="server"><br />
		<asp:TextBox ID="txtName" Runat="server" onkeyup="Javascript:setValue();"></asp:TextBox><br /><br />
		<asp:Label ID="lblName" Runat="server" /><br />
<br />
     </form><br />
	<br />
  </body><br />
</html><br />

Save this in a aspx file and then run. Note that it is not using any code-behind.

Thanks

For IE you can also use innerText. But it won't work in Mozilla. So using innerHTML is better.

How do you set the XMLDataSource property? in code-behind or in the web page? Are you sure that the value is not null by the time you set the property of the control?

I m setting through code behind and value is not null when i set it to XMLDataSource property. It assigns the value correctly because i have checked through debugging. I think there is some problem with declaring the control .. isnt it?

Ah yes, now I look at your sample code again and see the cause: You declare the control in the web page with the id UcMenu1, meanwhile you declare a new instance MyBar in code-behind, and I guess that you set the property of the second instance other than the first one. In this case, you can declare the control in code-behind like this: (in the version 2.0, you no need to this):

protected ucMenu UcMenu1;

I would suggest going to MSDN and working through some of the asp.net tutorials. Asp.net also does not use VB script directly - maybe you mean VB.net.

You can use asp.net validator controls and also you can use your own javascript to validate the text boxes in the datagrid. If you are using your own javascript then you have to call the javascript function on the click of the submit button and that you can attach in OnItemDataBound event of the datagrid.

you can access that textbox by something like Cells[1].Controls[1] and pass the ID to the javascript function.
