Hi Mahesh,

Please try the below code snippet to bind a RadComboBox in filter template.

ASPX:

<telerik:GridBoundColumn UniqueName="ContactTitle" DataField="ContactTitle" HeaderText="Contact title"                       HeaderStyle-Width="200px">
  <FilterTemplate>
    <telerik:RadComboBox ID="RadComboBox1" runat="server"></telerik:RadComboBox>
  </FilterTemplate>
</telerik:GridBoundColumn>

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
   {
       if (e.Item is GridFilteringItem)
      {
          GridFilteringItem item = (GridFilteringItem)e.Item;
          RadComboBox combo = (RadComboBox)item.FindControl("RadCombobox1");
          combo.DataSourceID = "SqlDataSource2";
          combo.DataTextField="ContactTitle";
          combo.DataValueField = "ContactTitle";
      }
   }

Thanks,
