We are aware of the described issue regarding the ColumnDefinition.Width
not updating its value when changed (via resizing for example). It is logged it in our Feedback Portal where you can track its progress:
If you wish to extract the width of the column definitions, I can only suggest finding the column header containers that are children of the RadGanttView
and get their ActualWidth
property. I've prepared a sample project demonstrating this - you can find it attached.
