RadGrid Filtering

[nisha]

Hi,

I have enabled filtering for the radgrid but its not working. I'm not sure what might be the reason for this. Also I want to enable filtering only for a particular column. Below is the  aspx code i'm using. Please let me how what should be modified in order to make the filtering option to work.

<telerik:RadTabStrip ID="RadTabStrip1" runat="server"
       Skin="Web20"
       ClickSelectedTab="True"
       PerTabScrolling="True"
       MultiPageID="RadMultiPage1"
       ReorderTabsOnSelect="True"
       ScrollChildren="True"
       SelectedIndex="0"
       ShowBaseLine="True">
       <Tabs>
           <telerik:RadTab runat="server" Text="test1" Selected="True">
           </telerik:RadTab>
           <telerik:RadTab runat="server" Text="test2" >
           </telerik:RadTab>

Hello Nisha.

From you code, I can see that you have not attached the NeedDataSource event or used DataSourceID for the grid. I am assuming that you are using Simple data-binding technique through the DataBind() method which can be used in simple scenarios which does not require complex operations like insert/delete/update, grouping, hierarchy relations, etc.

So, in your case I would suggest you to use Advanced Data-binding (using NeedDataSource event) to populate the grid. Here you can find more information about AdvancedDataBinding.
