The ColumnPositionChanged event's data class is EventArgs.

The column whose position has been changed is specified by the event’s sender parameter. To get the column’s position among visible columns in the Column Header Panel, use the GridColumn.VisibleIndex property.

The ColumnPositionChanged event also fires in the following cases:

• a column is moved to/from/within the group panel
• a column is moved to/from the Customization Form

C#

using DevExpress.XtraGrid.Columns;

private void gridView1_ColumnPositionChanged(object sender, EventArgs e) {
    GridColumn column = sender as GridColumn;
    MessageBox.Show(column.VisibleIndex.ToString());
}

VB.NET

Imports DevExpress.XtraGrid.Columns

Private Sub gridView1_ColumnPositionChanged(ByVal sender As Object, ByVal e As EventArgs) _
    Handles gridView1.ColumnPositionChanged
    Dim column As GridColumn = TryCast(sender, GridColumn)
    MessageBox.Show(column.VisibleIndex.ToString())
End Sub

To identify the column’s position within the group panel, use the GridColumn.GroupIndex property.
