The WebTree (gb.web.gui) doesnot show any content if it contains only one row. However the WebTree shows all its vontents properly if there are more than two rows


This example doesnot show content
  
  Dim pic1 As String

  WebTree1.Clear()
  WebTree1.Columns.Count = 1
  pic1 = "icon:/small/identity"
  WebTree1.Add("abc", "abcdef", pic1)
  

This example shows all contents


 Dim pic1 As String

  WebTree1.Clear()
  WebTree1.Columns.Count = 1
  pic1 = "icon:/small/identity"
  WebTree1.Add("abc", "abcdef", pic1)
  WebTree1.Add("def", "defghi", pic1)
