Örnekler

Aşağıdaki kod örneği,, TrueValue FalseValue ve NullValue özelliklerini ayarlar DataGridBoolColumn .The following code example sets the TrueValue, FalseValue, and NullValue properties of a DataGridBoolColumn.

private:

   void SetBoolColumnValues()
   {
      DataGridBoolColumn^ myGridColumn;
      
      // Get the DataGridBoolColumn you are setting.
      myGridColumn = dynamic_cast<DataGridBoolColumn^>(myDataGrid->TableStyles[ "Customers" ]->GridColumnStyles[ "Current" ]);
      
      // Set TrueValue, FalseValue, and NullValue.
      myGridColumn->TrueValue = true;
      myGridColumn->FalseValue = false;
      myGridColumn->NullValue = Convert::DBNull;
   }

private void SetBoolColumnValues(){
   DataGridBoolColumn myGridColumn;
   // Get the DataGridBoolColumn you are setting.
   myGridColumn = (DataGridBoolColumn) myDataGrid.
   TableStyles["Customers"].GridColumnStyles["Current"];
   // Set TrueValue, FalseValue, and NullValue.
   myGridColumn.TrueValue = true;
   myGridColumn.FalseValue = false;
   myGridColumn.NullValue = Convert.DBNull;
}

Private Sub SetBoolColumnValues()
   Dim myGridColumn As DataGridBoolColumn 
   ' Get the DataGridBoolColumn you are setting.
   myGridColumn = CType(myDataGrid.TableStyles _
