   {
      if ( myDataGridTextBox->IsInEditOrNavigateMode )
      {
         // DataGridTextBox has not been edited.
         MessageBox::Show( "Editing of DataGridTextBox not begun, IsInEditOrNavigateMode = True" );
      }
      else
      {         
         // DataGridTextBox has been edited.
         MessageBox::Show( "Editing of DataGridTextBox begun, IsInEditOrNavigateMode = False" );
      }
   }

// Handle event to show the state of 'IsInEditOrNavigateMode'.
private void Button_ClickEvent(object sender, EventArgs e)
{

   if (myDataGridTextBox.IsInEditOrNavigateMode)
   {
      // DataGridTextBox has not been edited.
      MessageBox.Show("Editing of DataGridTextBox not begun, IsInEditOrNavigateMode = True");
   }
   else
   {
      // DataGridTextBox has been edited.
      MessageBox.Show("Editing of DataGridTextBox begun, IsInEditOrNavigateMode = False");
   }
}

' Handle event to show the state of 'IsInEditOrNavigateMode'.
Private Sub Button_ClickEvent(sender As Object, e As EventArgs)
   
   If myDataGridTextBox.IsInEditOrNavigateMode Then
      ' DataGridTextBox has not been edited.
      MessageBox.Show("Editing of DataGridTextBox not begun,IsInEditOrNavigateMode = True")
   Else
      ' DataGridTextBox has been edited.
      MessageBox.Show("Editing of DataGridTextBox begun,IsInEditOrNavigateMode = False")
   End If
End Sub

注解

属性 IsInEditOrNavigateMode 用于 ProcessKeyMessage 确定如何处理键按下事件，以检查状态 DataGridTextBox。 例如，如果按下其中一个导航 (箭头) 键，则必须对控件的状态执行相应的操作。
