ColumnView.FocusedRowChanged Event

Fires when row focus moves from one row to another.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v19.2.dll

Declaration

C#

[DXCategory("Property Changed")]
public event FocusedRowChangedEventHandler FocusedRowChanged

VB.NET

<DXCategory("Property Changed")>
Public Event FocusedRowChanged As FocusedRowChangedEventHandler

Event Data

The FocusedRowChanged event's data class is FocusedRowChangedEventArgs. The following properties provide information specific to this event:

Property	Description
FocusedRowHandle	Gets the handle of the currently focused row.
PrevFocusedRowHandle	Gets the handle of the previously focused row.

Remarks

The FocusedRowChanged event is raised when the ColumnView.FocusedRowHandle property value changes.

Note

When the focus moves between Views, the FocusedRowChanged event is not raised. The grid control’s GridControl.FocusedViewChanged event is raised instead.

See ColumnView.FocusedRowObjectChanged to learn more.

Example

This example expands a collapsed group row and vice versa when this row receives focus.

C#

using DevExpress.XtraGrid.Views.Grid;
using DevExpress.XtraGrid.Views.Base;

private void gridView1_FocusedRowChanged(object sender, FocusedRowChangedEventArgs e) {
     GridView view = sender as GridView;
     if (view == null) return;
     if (view.IsGroupRow(e.FocusedRowHandle)) {
        bool expanded = view.GetRowExpanded(e.FocusedRowHandle);
        view.SetRowExpanded(e.FocusedRowHandle, !expanded);
     }
}

VB.NET

Imports DevExpress.XtraGrid.Views.Grid
Imports DevExpress.XtraGrid.Views.Base

Private Sub GridView1_FocusedRowChanged(ByVal sender As System.Object, _
  ByVal e As FocusedRowChangedEventArgs) Handles GridView1.FocusedRowChanged
   Dim view As GridView = sender
   If view Is Nothing Then
       Return
   End If
   If view.IsGroupRow(e.FocusedRowHandle) Then
      Dim expanded As Boolean = view.GetRowExpanded(e.FocusedRowHandle)
      view.SetRowExpanded(e.FocusedRowHandle, Not expanded)
   End If
End Sub
