Accessing DataKeyValues of DetailTable in standard Function

[marbleblue]

I have 3 levels of details tables within a rad grid.

The bottom details table contains a GridTemplateColumn with an image button which is linked to a RadToolTipManager.

On click, a Modal tooltip is displayed, but I need to access the datakeyvalues of the grid to send values to the Tooltip.

I can do this easily at a top level RadGrid table, but I cant seem to do it from a details table.

 

<DetailTables>
<telerik:GridTableView Name="gtv_account2" runat="server" DataKeyNames="InvoiceNumber, InvoiceDate, Outstanding">
.
<telerik:GridTemplateColumn UniqueName="gtv_account2_buttons">
<ItemTemplate>
<asp:ImageButton ID="Invoice_Query" CommandName="Invoice_Query" ImageUrl="~/Images/Icons/invoice_query.gif" runat="server" AlternateText="Click to query invoice" CausesValidation="false" />
.
.
.
<telerik:RadToolTipManager ID="RadToolTipManager_Query_Invoice" HideEvent="ManualClose" Modal="true" runat="server" OnAjaxUpdate="OnAjaxUpdate_Query_Invoice" RelativeTo="BrowserWindow">

</telerik:RadToolTipManager>

 

Clicking the image button launches the tooltip, and the function in the definition above it hit (OnAjaxUpdate_Query_Invoice).

How can I access the datakeyvalues in the following function?  

 

Protected Sub OnAjaxUpdate_Query_Invoice(ByVal sender As Object, ByVal args As ToolTipUpdateEventArgs)
.
End Sub

The following didn't work:

value = RadGrid1.MasterTableView.DetailTables(0).DataKeyValues(args.Value)("InvoiceNumber")

Thanks for any help!

Hello Kushel,

Try the following approach in RadToolTipManager's OnAjaxUpdate event:

((Page.FindControl(args.TargetControlID) as ImageButton).NamingContainer as GridDataItem).OwnerTableView.DataKeyValues(0);

This is, try to reference the ImageButton from inside the event. Once you reference the button, its NamingContainer is a reference to the parent GridDataItem from which you can access the OwnerTableView and its DataKeyValues.

Kind regards,
