Node OnClientNodeDropping to Grid

[Jason]

Hi,

I am trying to integrate a treeview and grid by dragging nodes to the grid to create records.  I have code working where I can drag a treenode to a grid and fire the code behind to insert a new record etc...

    Protected Sub ApplicationsTreeView_OnNodeDrop(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeDragDropEventArgs) Handles ApplicationsTreeView.NodeDrop

        If e.HtmlElementID = (ProjectApplicationsGrid.ClientID & "_GridData") Then

            Dim InsertRecordDataSource As SqlDataSource = ProjectApplicationsDataSource
            Dim Project_ID As Integer = CInt(Request.QueryString("Project_ID"))
            Dim Application_ID As Integer = CInt(e.SourceDragNode.Value)

            InsertRecordDataSource.InsertParameters("Project_ID").DefaultValue = Project_ID
            InsertRecordDataSource.InsertParameters("Application_ID").DefaultValue = Application_ID
            ProjectApplicationsDataSource.Insert()
            ProjectApplicationsGrid.Rebind()

        End If

The following function cancels the nodedrop postback if the node is dropped onto a treeview node.  But the postback also doesn't fire if the node is dropped onto a highlighted grid row.  I.e.  The code behind is only fired if I drag the treeview node onto a part of the grid that doesn't contain any rows.

        function ApplicationsTreeView_ClientNodeDropping(sender, args) {

            var dest = args.get_destNode();
            alert(dest);
            if (dest==null) { args.set_cancel(false); return; } else { args.set_cancel(true); return; } ;

        }

Hope you can help.

Thanks
Jase

Hello Jason,

Can you reproduce the problem on our online demo? I can drag a node from the first treeview to the grid with no problem?

Also, when you drag onto a highlighted row in the grid what is the value of the dest variable? Isn't it null?

All the best,
