  Hi,

  I am using an infragistics UltraTree control in Windows Application.

  I added context menu to it. When I right clicked on any node, I want to get the node at that point to displya the relevent information of that node. So I wrote the below code for that

  Private Sub tvXML_MouseUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles tvXML.MouseUp

  Dim newTreeNode As UltraTreeNode

  newTreeNode = tvXML.GetChildAtPoint(

  New Point(e.X, e.Y))

  DisplayInfo(newTreeNode)

  End Sub

  But, GetChildAtPoint() function always returns Nothing. so, I get nothing displayed.

  Please let me know if the way I am doing is correct.

  Thanks in advance.

  Vijay

  I got the solution for this.

  I must use GetNodeFromPoint()  instead of GetChildAtPoint()

  Thanks,

  Vijay

  Well I know for the standard TreeView control you use the method 'GetNodeAt' to retrieve the node at a given point.  It also has a method 'GetChildAtPoint' but this retrieves child controls not nodes.  Perhaps the UltraTree works the same way.  I'd look for a method 'GetNodeAt'.  If you are in fact using the correct method then I'm not sure what to tell you.  The basic logic and code looks fine to me.  Perhaps it's a bug with there control.  You might be better off going to them for support.

  I was just a little late :)  Glad you got it figured out.
