Property	Description
Column	Gets the column being processed.

Remarks

This event occurs in the following cases:

• an end-user has dragged a column’s right edge, and thus modified its width;
• a column’s width has been modified via the GridColumn.Resize method.

C#

private void gridView1_ColumnWidthChanged(object sender, DevExpress.XtraGrid.Views.Base.ColumnEventArgs e) {
    e.Column.Width = Math.Min(e.Column.Width, colAddress.Width);
}

VB.NET

Private Sub gridView1_ColumnWidthChanged(ByVal sender As Object, ByVal e As DevExpress.XtraGrid.Views.Base.ColumnEventArgs) _
    Handles gridView1.ColumnWidthChanged
    e.Column.Width = Math.Min(e.Column.Width, colAddress.Width)
End Sub

The ColumnWidthChanged event isn’t fired when a column’s width is changed via the GridColumn.Width property.

This event also isn’t fired when the following conditions are met:

• the GridOptionsView.ColumnAutoWidth option is set to true
• a column’s width is changed as a result of modifying the View’s width.
