  With a fixed width treeview column, is there a setting for a CustomContentPresenter for a text item that would re-wordwrap the text if:

  1. the user resizes the column
  2. the item is a child of the the node
     
     If I set both AutoWidth and AutoHeight properties for the TextElement and the RowPanel it sits in, the parent node renders correctly but the child cuts off part of the text.
     
     

  Thanks

  Oh and to add another question, is there a way to test if the C1TreeView vertical and/or horizontal scrollbars are visible?

  Hi Kingman!

  I found workaround for this case:

  
  if (c1TreeView1.IsHandleCreated)
              {
                  int wndStyle = GetWindowLong(c1TreeView1.Handle, GWL_STYLE);
  
                  bool vsVisible = (wndStyle & WS_VSCROLL) != 0;
                  System.Diagnostics.Debug.WriteLine("VSCROLL " + vsVisible);
  
                  bool hsVisible = (wndStyle & WS_HSCROLL) != 0;
                  System.Diagnostics.Debug.WriteLine("HSCROLL " + hsVisible);
              }
  
   internal const int
              WS_VSCROLL = 0x00200000,
              WS_HSCROLL = 0x00100000,
              GWL_STYLE = -16;
  
          [DllImport("user32.dll")]
          static private extern int GetWindowLong(IntPtr hWnd, int nIndex);

  Kingman,

  about first question, try set Style.WorWrap property of TextElement as true.

  var e = new TextElement();
  e.Style = new Style();
  e.Style.WordWrap = true;
