   {
      // Creates a DataSet named SuppliersProducts.
      DataSet^ SuppliersProducts = gcnew DataSet( "SuppliersProducts" );
      // Adds two DataTable objects, Suppliers and Products.
      SuppliersProducts->Tables->Add( gcnew DataTable( "Suppliers" ) );
      SuppliersProducts->Tables->Add( gcnew DataTable( "Products" ) );
      // Insert code to add DataColumn objects.
      // Insert code to fill tables with columns and data.
      // Binds the DataGrid to the DataSet, displaying the Suppliers table.
      dataGrid1->SetDataBinding( SuppliersProducts, "Suppliers" );
   }

private void BindControls(){
    // Creates a DataSet named SuppliersProducts.
    DataSet SuppliersProducts = new DataSet("SuppliersProducts");
    // Adds two DataTable objects, Suppliers and Products.
    SuppliersProducts.Tables.Add(new DataTable("Suppliers"));
    SuppliersProducts.Tables.Add(new DataTable("Products"));
    // Insert code to add DataColumn objects.
    // Insert code to fill tables with columns and data.
    // Binds the DataGrid to the DataSet, displaying the Suppliers table.
    dataGrid1.SetDataBinding(SuppliersProducts, "Suppliers");
 }

Private Sub BindControls()
    ' Create a DataSet named SuppliersProducts.
    Dim SuppliersProducts As New DataSet("SuppliersProducts")
    ' Adds two DataTable objects, Suppliers and Products.
    SuppliersProducts.Tables.Add(New DataTable("Suppliers"))
    SuppliersProducts.Tables.Add(New DataTable("Products"))
    ' Insert code to add DataColumn objects.
    ' Insert code to fill tables with columns and data.
    ' Binds the DataGrid to the DataSet, displaying the Suppliers table.
    dataGrid1.SetDataBinding(SuppliersProducts, "Suppliers")
End Sub

Remarks

You must use the SetDataBinding method at run time to reset the DataSource property.

See the DataSource property for more details about setting a valid data source.

You can create a grid that enables users to edit data but prevents them from adding new rows by using a DataView as the data source and setting the AllowNew property to false. When the DataSource is a DataView or DataTable, set the DataMember to an empty string ("").
