Hello Siva,

The following sample code shows how you can achieve this in server side. Attach SelectedIndexChanged event to DropDownList and using NamingContainer property of DropDownList access the grid item. Then find out corresponding control which you want to change using FindControl method and update its value.

ASPX:

<Columns>
   <telerik:GridTemplateColumn>
        <ItemTemplate>
            <asp:DropDownList ID="DropDownList1" runat="server"
              DataSourceID="SqlDataSource1" DataTextField="EmployeeID"
              DataValueField="EmployeeID" AutoPostBack="True"
              OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
            </asp:DropDownList>
        </ItemTemplate>
    </telerik:GridTemplateColumn>
    <telerik:GridTemplateColumn>
        <ItemTemplate>
            <asp:Label ID="Label1" runat="server" Text='<%#Eval("FirstName") %>'></asp:Label>
        </ItemTemplate>
    </telerik:GridTemplateColumn>
</Columns>

C#:

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
   {
       DropDownList list = (DropDownList)sender;
       GridDataItem item = (GridDataItem)list.NamingContainer;
       Label lb = (Label)item.FindControl("Label1");
       lb.Text = "new value";
   }

If you want to achieve this in client side, attach 'onChange' client event to DropDownList by passing item index to event handler. In that event handler identify the corresponding row using this index value and find out the control in that row that you wants to update.

Java Script:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
      if (e.Item is GridDataItem)
       {
           GridDataItem item = (GridDataItem)e.Item;
           DropDownList list = (DropDownList)item.FindControl("DropDownList1");
           list.Attributes.Add("onChange","OnSelectedIndexChange('"+item.ItemIndex+"');");
       }
    }

Java Script:

<script type="text/javascript">
   function OnSelectedIndexChange(rowindex) {
        var grid = $find("<%=RadGrid1.ClientID %>");
        var MasterTable = grid.get_masterTableView();
        var row = MasterTable.get_dataItems()[rowindex];
        row.findElement("Label1").innerHTML = "new value";
    }
</script>

Thanks,
Princy.
