Can you check whether you've changed the default RadTreeView HorizontalAlignment
property value? If you haven't, then it is Stretch
, which means that the control will take up as much space as possible - actually it will take as much space as its container allows it to take.
And in your case, even if you apply an Auto Width
, as long as the HorizontalAlignment
of the control is Stretch
, the control will try to take all available space. Instead, if you set the HorizontalAlignment
, the control will take only as much space as it needs to display its children.
Having the above information in mind, please try setting HorizontalAlignment
and get back to us if that doesn't help.
