Hello Nagesh,

Check out the following code and see if it helps meet your requirement:
aspx:

    
            <telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" runat="server"> 
        
                <MasterTableView DataSourceID="SqlDataSource1"> 
        
                     <DetailTables> 
        
                          <telerik:GridTableView DataSourceID="SqlDataSource1" runat="server">                             
        
                             <Columns> 
        
                                 <telerik:GridTemplateColumn UniqueName="GridTemplateColumn1" HeaderText="Column1">  
        
                                      <ItemTemplate>   
        
                                              <telerik:RadComboBox ID="RadComboBox1" DataSourceID="SqlDataSource1" DataTextField="Category" DataValueField="Category" runat="server" AutoPostBack="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"></telerik:RadComboBox>                                   
        
                                      </ItemTemplate>   
        
                                 </telerik:GridTemplateColumn> 
        
                                 <telerik:GridTemplateColumn UniqueName="GridTemplateColumn2" HeaderText="Column2">                                   
        
                                      <ItemTemplate>   
        
                                              <telerik:RadComboBox ID="RadComboBox2" runat="server"></telerik:RadComboBox> 
        
                                      </ItemTemplate>   
        
                                 </telerik:GridTemplateColumn> 
        
                                   ....

c#:

    
            protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e) 
        
                { 
        
                    RadComboBox combo1 = (RadComboBox)o; 
        
                    GridDataItem dataItem = (GridDataItem)combo1.NamingContainer; 
        
                    RadComboBox combo2 = (RadComboBox)dataItem.FindControl("RadComboBox2"); 
        
                    if (combo1.Text == "Category1") 
        
                    { 
        
                        combo2.DataSourceID = "SqlDataSource2"; 
        
                        combo2.DataTextField = "Name";             
        
                    } 
        
                }

Hope this helps..
