DevExpress XtraGrid网格控件示例二：利用快捷键删除行

本文的代码示例主要展示当终端用户按下Ctrl+Del 快捷键时，删除焦点行的操作。要处理按键事件，首先我们需要处理BaseView.KeyDown事件。然后通过调用ColumnView.DeleteRow 方法，删除焦点行。

C#

private void gridView1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e) {
if (e.KeyCode == Keys.Delete && e.Modifiers == Keys.Control) {
if (MessageBox.Show("Delete row?", "Confirmation", MessageBoxButtons.YesNo) != 
DialogResult.Yes)
return;
GridView view = sender as GridView; 
view.DeleteRow(view.FocusedRowHandle);
}
}

VB

Private Sub GridView1_KeyDown(ByVal sender As Object, _
ByVal e As System.Windows.Forms.KeyEventArgs) Handles GridView1.KeyDown
If (e.KeyCode = Keys.Delete And e.Modifiers = Keys.Control) Then
If (MessageBox.Show("Delete row?", "Confirmation", _
MessageBoxButtons.YesNo) <> DialogResult.Yes) Then Return
Dim view As GridView = CType(sender, GridView)
view.DeleteRow(view.FocusedRowHandle)
End If
End Sub
