[Solved] Access GridDataItem containing RadToolBar in RadGrid

[The Wire]

I have a RadToolBar (tbActions) within a GridTemplateColumn in a RadGrid.  When I click a button in tbActions, I want to access the ID column of the GridDataItem row that contains the tbActions that I just clicked in.  How can I get that reference?

<rad:RadGrid ...>

        <MasterTableView ...>

            <Columns>

                <rad:GridBoundColumn DataField="ID" UniqueName="ID" />
                <!--...more columns...-->

                <rad:GridTemplateColumn UniqueName="Actions">

                    <ItemTemplate>

                        <rad:RadToolBar ID="tbActions" Orientation="Horizontal" runat="server"

                            OnButtonClick="tbActions_OnButtonClick" >

                            <Items>

                                <rad:RadToolBarButton ImageUrl="images/button1.png" Value="1" />

                                <rad:RadToolBarButton ImageUrl="images/button2.png" Value="2" />

                                <rad:RadToolBarButton ImageUrl="images/button3.png" Value="3" />

                            </Items>

                        </rad:RadToolBar>

                    </ItemTemplate>

                </rad:GridTemplateColumn>

            </Columns>

            <DetailTables>

                ...            

            </DetailTables>

        </MasterTableView>

    </rad:RadGrid>

protected void tbActions_OnButtonClick(object sender, RadToolBarEventArgs e)

{

    //How can I get a reference to the GridDataItem that contains the toolbar

    //of the button that I just clicked?

    //this is not working:

    GridDataItem item = (GridDataItem)e.Item.ToolBar.Parent.Parent;

         string id;

    if (e.Item.Value == "1")

    {

          id = item["ID"].Text;
          //more code here, use ID for db update 

    }

    else if (e.Item.Value == "2")

    {

          id = item["ID"].Text;
          //more code here, use ID for db update
    }

    else if (e.Item.Value == "3")

    {

          id = item["ID"].Text;
          //more code here, use ID for db update


    }

}

I don't see a problem with your code. I tried your code myself as was able to get the GridDataItem object and retrieve the ID column's text.

Is your code failing at that point?

My mistake.  I had thought that line was the problem, but I found the problem in my "//more code here, use ID for db update" section.  I was trying to assign a value to sqldatasource parameter using the wrong parameter name.  I guess I just needed a lunch break to clear out my mind :)

Thanks!

Ok, how can I do this client side?

So far I have

function tbActionsClick(sender, args) {
  var item = args.get_item();
  if (item.get_value() == "1") {
    var tb = item.get_toolBar();
    //now if it's like server side, i need 2 calls to get_parent() to get the row
    var cell = tb.get_parent();
    var row = cell.get_parent();
    var grid = row.get_masterTableView();
    var id = grid.getCellByColumnUniqueName(row, "ID");
  }
}

I don't think I'm getting the objects I expect when I assign row and cell.

I have a workaround that is fine for me, although I still am curious to know how to do what I was originally trying to do.

My workaround was to, in the server-side RadGrid OnItemDataBound event, assign attributes to the toolbar button.  These attributes included the ID value I wanted.

protected void RadGrid_OnItemDataBound(object sender, GridItemEventArgs e)
{
  GridDataItem item = (GridDataItem)e.Item;
  RadToolBar tbActions = (RadToolBar)item["Toolbar"].FindControl("tbActions");

  tbActions.Items[0].Attributes["ID"] = item["ID"].Text;
}

Then in client-side, I referenced the attributes collection of the button:

function tbActionsClick(sender, args) {
  var item = args.get_item();
  if (item.get_value() == "1") {
    var id = item.get_attributes().getAttribute("ID");
  }
}
