ContextMenu in Hierarchical RadGrid

[Steve]

I have a RadGrid where the MasterTableView has a single DetailTable.  When right-clicking on a row in a DetailTable, a ContextMenu is displayed to perform various operations on the row.

I've successfully grabbed the index of the DetailTable row that was clicked on in the client-side event handler "OnRowContextMenu" and put it in a hidden field, so I can access it in the RadMenu.OnItemClick event handler.  That works just fine; I can grab the value from the hidden field.

What I need to do is get a handle on the GridDataItem associated with the row, and (more importantly) the GridDataItem of the DetailTable row's parent.  How do I do this?  It seems like a pretty common thing someone might need to do when using the ContextMenu with RadGrid.  REALLY need help on this one.  Thanks.

Hi,

You can easily get the dataItem of the parent in the context menu item click of the child table:

  protected void RadMenu1_ItemClick(object sender, RadMenuEventArgs e)
    {
int radGridClickedRowIndex;
        string UId;

        string[] indices = Request.Form["radGridClickedRowIndex"].Split('_');
        radGridClickedRowIndex = Convert.ToInt32(indices[indices.Length - 1]);
        UId = Request.Form["radGridClickedTableId"];

        GridTableView tableView;

        switch (e.Item.Text)
        {
            case "Select":
                tableView = this.Page.FindControl(UId) as GridTableView;
                GridDataItem item = (GridDataItem)tableView.ParentItem;
                item.BackColor=System.Drawing.Color.Red;
    }

    }

Thanks,

How do you get the the ID of the DetailTable in the client-side handler for "OnRowContextMenu"?

Hello Steve,

I assumed that you had retrieved the index of of the DetailTable row. Here is the code to access the DetailTable ID on the client side.
cs:

 <script type="text/javascript">
                function RowContextMenu(sender, eventArgs)
                {
                     var menu = $find("<%=RadMenu1.ClientID %>");
                     menu.show(eventArgs.get_domEvent());

                     document.getElementById("radGridClickedRowIndex").value = eventArgs.get_itemIndexHierarchical();
                     var ownerTable = eventArgs.get_tableView();

                     document.getElementById("radGridClickedTableId").value = ownerTable._data.UniqueID;
                }
                </script>

Regards,
Princy.

I had retrieved the row but wasn't sure how to get the table ID.  Thanks so much for your help.  I'll give it a try.
