DataGrid.Navigate 事件

在用户浏览到新表时发生。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Event Navigate As NavigateEventHandler
用法
Dim instance As DataGrid
Dim handler As NavigateEventHandler

AddHandler instance.Navigate, handler

public event NavigateEventHandler Navigate

public:
event NavigateEventHandler^ Navigate {
    void add (NavigateEventHandler^ value);
    void remove (NavigateEventHandler^ value);
}

/** @event */
public void add_Navigate (NavigateEventHandler value)

/** @event */
public void remove_Navigate (NavigateEventHandler value)

JScript 支持使用事件，但不支持进行新的声明。

备注

使用 Navigate 事件将单个列属性（如 width）重置为适合该表的值。

' Create an instance of the 'Navigate' NavigateEventHandler.
Private Sub CallNavigate()
   AddHandler myDataGrid.Navigate, AddressOf Grid_Navigate
End Sub 'CallNavigate


' Raise the event when navigating to another table.
 Private Sub Grid_Navigate(ByVal sender As Object, ByVal e As NavigateEventArgs)
     ' String variable used to show message.
     Dim myString As String = "Navigate event raised, moved to another table"
     ' Show the message when navigating to another table.
     MessageBox.Show(myString, "Table navigation information")
 End Sub 'Grid_Navigate

// Instantiate the 'Navigate' NavigateEventHandler.
private void CallNavigate()
{
   myDataGrid.Navigate += new NavigateEventHandler(Grid_Navigate);
}

// Raise the event when navigating to another table.
private void Grid_Navigate(object sender, NavigateEventArgs e)
{
   // String variable used to show message.
   string myString = "Navigate event raised, moved to another table";
   // Show the message when navigating to another table.
   MessageBox.Show(myString, "Table navigation information");
}

   // Instantiate the 'Navigate' NavigateEventHandler.
private:
   void CallNavigate()
   {
      myDataGrid->Navigate += gcnew NavigateEventHandler( this, &MyDataGrid::Grid_Navigate );
   }

   // Raise the event when navigating to another table.
private:
   void Grid_Navigate( Object^ /*sender*/, NavigateEventArgs^ /*e*/ )
   {
      // String variable used to show message.
      String^ myString = "Navigate event raised, moved to another table";
      
      // Show the message when navigating to another table.
      MessageBox::Show( myString, "Table navigation information" );
   }

// Instantiate the 'Navigate' NavigateEventHandler.
private void CallNavigate()
{
    myDataGrid.add_Navigate(new NavigateEventHandler(GridNavigate));
} //CallNavigate

// Raise the event when navigating to another table.
protected void GridNavigate(Object sender, NavigateEventArgs e)
{
    // String variable used to show message.
    String myString = "Navigate event raised, moved to another table";
