Bug - ColumnWidthChanged has incorrect values.

[Rob]

In the ColumnWidthChangedEventArgs object received by the ColumnWidthChanged event the "e.NewValue" does not contain the complete new column settings.  In particular, I am trying to get the pixel size of the column that has been set to "Auto" by double clicking the drag handle.

Hi Rob,

 

ColumnWidthChanged is fired once user tries to resize or double click on the resizer. As you have found out it contains information about the original and the current column width. When user resizes  the column using drag the current width can be measured in absolute units (pixels). However, if the user double-clicks the width become auto (fit to contents) and thus it cannot be measured in absolute units until the measures finishes.

If we need to acquire the absolute width of the column after the measure is complete I can suggest using code similar to the one below:

if(e.NewWidth.IsAuto)
{
      this.radGridView.Dispatcher.BeginInvoke((Action)(()=>YourMethodHere(e.Column.ActualWidth)));
}

All the best,
