Hi!

I have a search function here, where it will capture every keypress in the textbox and produce the results immediately in gridview (live search).

I am having problem to highlight the search results in the gridview.
Lets say, I type goo in the textbox ,google name will appear in gridview and only the word goo will be highlighted in the gridview.

Now,when I type the keyword in the textbox, then it will highlight the matching word but the word highlight gets disappeared.

Here is my aspx code :

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="HighlightTest1._Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<%@ Register Assembly="RealTimeSearch" Namespace="RealTimeSearch" TagPrefix="cc1" %>

        <asp:Label ID="Label1" runat="server" Text="Test Highlight 2"></asp:Label>


        </form>
</body>
</html>

Can anyone see any errors in this code? Any suggestion/modification to the code?
