Autosizing left column width

Hi,

 The first time I set the grid's SelectedObject to something, the left column width sizes to fit the longest property name.  But from then on, the left column width does not change size as I select other objects.  Is there a way to command the grid to always auto size the left column to fit the longest property name?

 Thanks

Hi Tom,

We don't currently have that feature but will add it to the wishlist.  I'm afraid I don't have any great ideas for a workaround either unfortunately.  Here is my best suggestion (untested!):

The columns are defined in the PropertyGrid default template, which is implemented as a TreeListView.  To get at this TreeListView, you need to derive from PropertyGrid; this is necessary to call the protected method GetTemplateChild.  So create a derived class with an "autosize now" method.  In that method, call GetTemplateChild("PART_Grid").  If this returns a TreeListView (which it will in the default template), set TreeListView.Columns[0].Width to Double.NaN (the magic number for autosize).

As warned, I haven't tried this so no promises I'm afraid.  Also, we don't expose a SelectedObjectChanged event or overridable method that you could hook, so you would need to call the "autosize now" method from code.

Setting TreeListView.Columns[0].Width in the derived class method does change the column width, but  the value Double.NaN doesn't seem to have any effect.

So I call TextRenderer.MeasureText() on all the nodes and set the column to the width of the longest human name I find.  It works well.

 Thanks.
