DataGrid.DataSourceChanged 事件

在 DataSource 属性值更改后发生。

**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 DataSourceChanged As EventHandler
用法
Dim instance As DataGrid
Dim handler As EventHandler

AddHandler instance.DataSourceChanged, handler

public event EventHandler DataSourceChanged

public:
event EventHandler^ DataSourceChanged {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}

/** @event */
public void add_DataSourceChanged (EventHandler value)

/** @event */
public void remove_DataSourceChanged (EventHandler value)

JScript 支持使用事件，但不支持进行新的声明。

备注

DataSourceChanged 事件发生在 DataMember 值发生更改或当 DataGrid 的 BindingContext 发生更改时。

示例

Private dataGrid1 As System.Windows.Forms.DataGrid


Private Sub CreateDataGrid()
    dataGrid1 = New DataGrid()
    ' Add the handler for the DataSourceChanged event.
    AddHandler dataGrid1.DataSourceChanged, AddressOf DataGrid1_DataSourceChanged
End Sub 'CreateDataGrid
 

Private Sub DataGrid1_DataSourceChanged(sender As Object, e As EventArgs)
    Dim thisGrid As DataGrid = CType(sender, DataGrid)
End Sub 'DataGrid1_DataSourceChanged

private System.Windows.Forms.DataGrid dataGrid1;
 
 private void CreateDataGrid()
 {
    dataGrid1 = new DataGrid();
    // Add the handler for the DataSourceChanged event.
    dataGrid1.DataSourceChanged += new EventHandler(DataGrid1_DataSourceChanged);
 
 }
 
 private void DataGrid1_DataSourceChanged(object sender, EventArgs e)
 {
    DataGrid thisGrid = (DataGrid) sender;
 }
    

private:
   System::Windows::Forms::DataGrid^ dataGrid1;

   void CreateDataGrid()
   {
      dataGrid1 = gcnew DataGrid;
      // Add the handler for the DataSourceChanged event.
      dataGrid1->DataSourceChanged += gcnew EventHandler(
         this, &Form1::DataGrid1_DataSourceChanged );
   }

   void DataGrid1_DataSourceChanged( Object^ sender, EventArgs^ /*e*/ )
   {
      DataGrid^ thisGrid = dynamic_cast<DataGrid^>(sender);
   }

private System.Windows.Forms.DataGrid dataGrid1;
private void CreateDataGrid()
{
    dataGrid1 = new DataGrid();
    // Add the handler for the DataSourceChanged event.
    dataGrid1.add_DataSourceChanged(
        new EventHandler(dataGrid1_DataSourceChanged));
} //CreateDataGrid

private void dataGrid1_DataSourceChanged(Object sender, EventArgs e)
{
    DataGrid thisGrid = (DataGrid)(sender);
} //dataGrid1_DataSourceChanged
