语法

声明
Public Property IsInEditOrNavigateMode As Boolean
用法
Dim instance As DataGridTextBox
Dim value As Boolean

value = instance.IsInEditOrNavigateMode

instance.IsInEditOrNavigateMode = value

public bool IsInEditOrNavigateMode { get; set; }

public:
property bool IsInEditOrNavigateMode {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_IsInEditOrNavigateMode ()

/** @property */
public void set_IsInEditOrNavigateMode (boolean value)

public function get IsInEditOrNavigateMode () : boolean

public function set IsInEditOrNavigateMode (value : boolean)

属性值

如果控件处于导航模式，而且编辑还没有开始，则为 true；否则为 false。默认为 true。

备注

IsInEditOrNavigateMode 属性用在 ProcessKeyMessage 中来确定如何处理按键事件和检查 DataGridTextBox 的状态。例如，如果按下导航（箭头）键之一，则对应于该控件状态的操作必须发生。

' 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 'Button_ClickEvent

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

   if (myDataGridTextBox.IsInEditOrNavigateMode)

   }
   else

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