Hi Jeff,

Please update the forum if you would like to discuss this case further.

Hi,

I have implemented a project using your code, the WebGrid uses 500 records. I have  tested using IE8 and I am not able to reproduce the issue.  Since you have set sorting on the client the first time it sorts will take time.  Sorting after that doesn't take 2-3 seconds for 500 records. We can do a live meeting to look at the issue further. You can also set sorting on the server and test. Or use XmlLoadOnDemand or the new Aikido control the WebDataGrid.

Please send  me regarding any questions.

Your samples don't include an UltraWebGrid.

All my grids exhibit the issue in ie8 and not ie7 and are defined similar to the following:

            <igtbl:UltraWebGrid ID="dgAssets" runat="server" DataMember="Default" DataSourceID="dsAssets"
                Width="1000px" OnDeleteRow="dgAssets_DeleteRow" OnClickCellButton="dgAssets_ClickCellButton"
