How to update controls[DataGrid,TextBoxes and Label] based on a row selection made in DataGrid that resideds in a updatePanel?

Question

I have got a grid[Grid1] that build its dataRows when a button[search] is clicked, I managed to Ajaxify it by placing it in an UpdatePanel and it worked fine. Before Ajaxifying Grid 1, another grid[Grid2] and some other controls[Text and Labels] used to get populated/updated when a row in Grid 1 was clicked .

The Grid2 and other controls used to get populated/updated on the OnItemCommand Event of Grid 1.Its the code in the OnItemCommand that binds the related data to Grid2 and other controls.

After I placed the Grid 1 in the update panel,they stopped updating. It will work fine if I place Grid2 and other controls in the same Update Panel but the page is designed in a way that I cant have those controls in the same UpdatePanel as the first Grid nor I dont intend to use another Update Panel.

I hope I'm making some sense. I'm a newbie in .Net so please excuse. Please find the code below.

 <asp:ScriptManager EnablePartialRendering="true" ID="ScriptManager1" runat="server"></asp:ScriptManager>
     <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers ="True">
      <ContentTemplate>
       <asp:DataGrid ID="grdJobs" runat="server" AllowPaging="true" 
        AlternatingItemStyle-CssClass="gridAltItemStyle"
        AutoGenerateColumns="False" CellPadding="0" 
        DataKeyField="code"
        CssClass="datagridBox" 
        GridLines="horizontal" 
        PagerStyle-Mode="NumericPages"
        HeaderStyle-CssClass="gridHeaderStyle" 
        ItemStyle-CssClass="gridItemStyle"
        PagerStyle-CssClass="gridPagerStyle" 
        Width="445px" OnPageIndexChanged="grdJobs_PageIndexChanged" OnItemCreated="grdJobs_ItemCreated" OnItemCommand="grdJobs_ItemCommand"             OnItemDataBound="grdJobs_ItemDataBound">
         <Columns>
          <asp:BoundColumn  DataField="J_ID" HeaderText="Job"></asp:BoundColumn>
          <asp:BoundColumn  DataField="Contract" HeaderText="Contract" ReadOnly="True"></asp:BoundColumn>
          <asp:BoundColumn  DataField="J_Fault_Line1" HeaderText="Fault" ReadOnly="True"></asp:BoundColumn>
          <asp:BoundColumn  DataField="j_p_id" HeaderText="Fault" Visible="false" ></asp:BoundColumn>
          <asp:ButtonColumn Text="<img src=images/addFeedback.gif style=border: 0px; alt=Add Feedback>" ButtonType="LinkButton"  HeaderText="Add"                   CommandName="Load" ItemStyle-cssClass="Col_9_Item_2"></asp:ButtonColumn>
         </Columns>
        </asp:DataGrid>
       <asp:ImageButton ID="cmdLkp"  ImageUrl="Images/search.gif" runat="server" OnClick="cmdLkp_Click" />

       </ContentTemplate>
      </asp:UpdatePanel>

The code below in the code behind stopped working

protected void grdJobs_ItemCommand(object source, DataGridCommandEventArgs e)
    {

        if (e.CommandName == "Load")
        {
            functionToBindDataToGrid2();
            functionToBindDataToOtherControls();
        }
}

 protected void grdJobs_ItemDataBound(object sender, DataGridItemEventArgs e)
    {
      e.Item.Attributes.Add("onclick", "javascript:__doPostBack('grdJobs$ctl" + ((Convert.ToInt32(e.Item.ItemIndex + 3).ToString("00"))) + "$ctl00','')");
     }

Answer 1

In the properties for the UpdatePanel, set the update mode to "Conditional" and ChildrenAsTriggers to "true".

Another option would be to move the button inside the update panel so that you wouldn't have to have the trigger.
