  I am trying to implment the ability for another control to drag and drop onto tabs in a radTabStrip.  I have been able to implment most of it, but am having difficulty determining which tab the user dropped on. 
  
  I would have thought I could put the following code in the DragDrop event of the TabStrip, but the GetItemByPoint always returns nothing, even when tabs were dropped on.
  
  

  Dim tab As Telerik.WinControls.UI.TabItem

  tab = radTabStrip.TabStripElement.GetItemByPoint(New Point(e.X, e.Y))

  If tab IsNot Nothing Then

  MsgBox(tab.Name)

  End If

  
  Any help would be appreciated.
  
  I am using VB.NET in VS2008
  
  Thank you -- controls are still fantastic

  Hi Marc,
  
  Thanks for writing.
  You can get a reference to the tab you are dropping on by iterating over the Items collection of the RadTabStrip and checking if its Bounds property contains the point that you clicked on. A somewhat subtle detail is that you have to convert the Bounds rectangle to screen coordinates since e.X and e.Y are in screen coordinates.
  Here is the code:
  

  Private Sub RadTabStrip1_DragDrop(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles RadTabStrip1.DragDrop

  Dim i As Integer

  Dim p As Point

  p.X = e.X

  p.Y = e.Y

  For i = 0 To RadTabStrip1.Items.Count - 1

  If RadTabStrip1.Items(i).RectangleToScreen(RadTabStrip1.Items(i).Bounds).Contains(p) Then

  MessageBox.Show("Found tab item! This is " + RadTabStrip1.Items(i).Text)

  RadTabStrip1.Items(i).Text = e.Data.GetData(GetType(String)).ToString()

  RadTabStrip1.Items(i).ForeColor = Color.Red

  End If

  Next

  End Sub

  Please do write again if you have more questions.
  
  All the best,
