RadGrid Filter not working

[prasadsa01]

I have two filter columns in my grid; however, only one filter (Status) is working. The second filter (Classification) is not working ( alone or in combination with first). I followed Demo example from https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/filter-templates/defaultvb.aspx

 

 <telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" Width="100%"   AllowFilteringByColumn="True"
            AllowSorting="True" AllowPaging="True" PageSize="7" runat="server" AutoGenerateColumns="False"
            ShowStatusBar="true" EnableLinqExpressions="false">
            <MasterTableView DataKeyNames="InstitutionID" TableLayout="Fixed">

Hello,

The code seems fine and there is nothing obviously wrong with it. Can you confirm there are no errors thrown and that the data in the column is strings that can be compared against the current string? Also, can you confirm you are providing the same data source to the grid every time: https://www.telerik.com/support/kb/aspnet-ajax/grid/details/how-to-bind-radgrid-properly-on-server-side? I am also attaching below an example I built on top of the provided code that seems to work fine for me. You can use it as for a comparison against the problematic code to find the origin of the problem. If you are still unable to resolve it, I would recommend opening a support ticket so you can send us a runnable example that reproduces the grid issue so we can investigate.
