ColumnView.ColumnChanged Event

Fires when changing a column’s properties.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v19.1.dll

Declaration

C#

[DXCategory("Property Changed")]
public event EventHandler ColumnChanged

VB.NET

<DXCategory("Property Changed")>
Public Event ColumnChanged As EventHandler

Event Data

The ColumnChanged event's data class is EventArgs.

Remarks

The ColumnChanged event is raised when the properties affecting column data representation are changed. The column whose properties have changed is identified by the event’s sender parameter. The event is used internally by Views. Generally, you will have no need to handle it in your own application.

C#

private void gridView1_ColumnChanged(object sender, EventArgs e) {
    GridColumn column = sender as GridColumn;
    MessageBox.Show("The " + column.Caption + " column has changed");
}

VB.NET

Private Sub gridView1_ColumnChanged(ByVal sender As Object, ByVal e As EventArgs) _
    Handles gridView1.ColumnChanged
    Dim column As GridColumn = TryCast(sender, GridColumn)
    MessageBox.Show("The " & column.Caption & " column has changed")
End Sub

You may need to respond to sorting or grouping a View against specific column values. For this purpose, handle the ColumnView.EndSorting and ColumnView.EndGrouping events respectively.
