I am populating a treeview control from a database. I want to allow the user to drag and drop nodes to arrange the nodes in a sort order. I was trying to use the DragEnded event to get the new position in the tree and update the new position in the database. I thought I could use the IndexOf to get the new position in the tree the node is located. If I drag a root node the Items.IndexOf for the dragged node returns the correct position, lower level nodes return -1. The code I am using is as follows:

    
                Private Sub RadTreeView1_DragEnded(ByVal sender As Object, ByVal e As Telerik.Windows.Controls.RadTreeViewDragEndedEventArgs) Handles RadTreeView1.DragEnded  
        
                    Dim newSortOrder As Integer 
        
                    Dim parentId As Integer 
        
                    Dim draggedItem As RadTreeViewItem = e.DraggedItems(0)  
        
                    Dim eStore As eStoreDataDataContext = New eStoreDataDataContext  
        
                    If IsNothing(draggedItem.ParentItem) Then 
        
                        ' no parent then item is root node  
        
                        parentId = 0  
        
                    Else 
        
                        parentId = draggedItem.ParentItem.Tag.ToString  
        
                    End If 
        
                    newSortOrder = RadTreeView1.Items.IndexOf(draggedItem)  
        
                    MsgBox("parentId = " & parentId.ToString)  
        
                    MsgBox("newSortOrder = " & newSortOrder.ToString)  
        
                End Sub

I am using the tag property to identify the parentId value in my database table. Does anyone know why the Items.IndexOf returns a number corresponding to the order the item is displayed in the tree for root node items and -1 for all other nodes?

Thanks.

[Solved] Scrolling a cell into view

I see there's an API to scroll a record into view:

RadGridView.ItemsControl.BringRecordIntoView

But I also need the ability to insure that a specific cell is also in view (if the grid has horizontal scroll bars), but I see no public API to do this.

[Solved] How Complex Can I Get?

I am reviewing the Telerik RadGridView for WPF. I've seen the demos and like what I see; however, the demos are quite simplistic. How innovative will I be able to get with the grid? Are there more examples out there?

My Needs:
I would like to have a nested grid within a cell.

Or, I may want the ability to have different custom lookups within the same column for different rows depending on a given type. For example, row 1 may identify product A so column A may need a date lookup in Column 5. However, row 2 may be for a different product and column 5 may need a card layout lookup for that row.

Are these possible?

Thank You.

It keeps timing out the download right at the end - tried in a couple of different browsers. Is it just really busy right now?

I guess I'm getting what I paid for... :)
