Assembly: System.Windows.Forms (in system.windows.forms.dll)

Syntax

'Declaration
Public Event DataSourceChanged As EventHandler
'Usage
Dim instance As DataGrid
Dim handler As EventHandler

AddHandler instance.DataSourceChanged, handler

public event EventHandler DataSourceChanged

public:
event EventHandler^ DataSourceChanged {

Das DataSourceChanged-Ereignis tritt ein, wenn der DataMember-Wert geändert oder der BindingContext des DataGrid gewechselt wird.

Weitere Informationen zum Behandeln von Ereignissen finden Sie unter Behandeln von Ereignissen.

Beispiel

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
