[Visual Basic, C#, C++] 以下示例通过 DefaultView 属性设置 DataTable 对象的 DataView 的属性。该示例还显示 DataGrid 控件与名为“Suppliers”的 DataTable 的绑定，DataTable 包括名为“CompanyName”的列。

[Visual Basic] Private Sub BindDataGrid()   Dim myDataTable As New DataTable   ' Insert code to populate a DataTable with data.   ' Bind DataGrid to DataTable   DataGrid1.DataSource = myDataTableEnd Sub Private Sub ChangeRowFilter()   Dim gridTable As DataTable = CType(dataGrid1.DataSource, DataTable)   ' Set the RowFilter to display a company names that begin with A through I.   gridTable.DefaultView.RowFilter = "CompanyName < 'I'"End Sub[C#] private void BindDataGrid(){   DataTable myDataTable = new DataTable();      // Insert code to populate a DataTable with data.   // Bind grid to DataTable.   dataGrid1.DataSource = myDataTable;}private void ChangeRowFilter(){   DataTable gridTable = (DataTable) dataGrid1.DataSource;   // Set the RowFilter to display a company names that begin with A through I..   gridTable.DefaultView.RowFilter = "CompanyName < 'I'";}[C++] private: void BindDataGrid(){    DataTable* myDataTable = new DataTable();        // Insert code to populate a DataTable with data.    // Bind grid to DataTable.    dataGrid1->DataSource = myDataTable; }  void ChangeRowFilter(){    DataTable* gridTable = dynamic_cast<DataTable*> (dataGrid1->DataSource);    // Set the RowFilter to display a company names that begin with A through I..    gridTable->DefaultView->RowFilter = S"CompanyName < 'I'"; }
