Hi,

You can do like this!

<asp:label runat="server" text="MyValue" ID="MyLabel"></asp:Label>

//At the end of the page
<script type="text/javascript">
var labelText = document.getElementByID("<%=MyLabel.ClientID%>").innerHTML;

//Perform substring operations
//...

//Finally update the value!
document.getElementByID("<%=MyLabel.ClientID%>").innerHTML = "Your value";

</script>

Hope it helps u...

Thanks & Regards

Its a bit complex one, u could use Expression Builders. Below link may help u

http://weblogs.asp.net/infinitiesloop/archive/2006/08/09/The-CodeExpressionBuilder.aspx

U have to do the following

1) Add the following class

using System.Web.Compilation;

[ExpressionPrefix("Code")]
public class CodeExpressionBuilder : ExpressionBuilder
{
    public override CodeExpression GetCodeExpression(BoundPropertyEntry entry,
        object parsedData, ExpressionBuilderContext context)
    {
        return new CodeSnippetExpression(entry.Expression);
    }
}

2) Add the following setting in ur web config

  <system.web>
    <compilation debug="true" targetFramework="4.0" >
      <expressionBuilders>
        <add expressionPrefix="Code" type="Namespace.CodeExpressionBuilder"/>
      </expressionBuilders>
    </compilation>

3) And alter ur label in markup as below

<asp:label ID = "lbl1" runat="server" Text= "<%$ Code: value.Substring(2,5)  %>" ></asp:label>

I reckon 'value' is defined in ur code behind as below

    public partial class WebForm1 : System.Web.UI.Page
    {
        public string value { get; set; }
