Esempio

Nell'esempio di codice seguente viene stampata informazioni su ognuna DataGridColumnStyle di esse in un oggetto GridColumnStylesCollection.

void PrintColumnInformation( DataGrid^ grid )
{
   Console::WriteLine( "Count: {0}", grid->TableStyles->Count );
   GridColumnStylesCollection^ myColumns;
   DataGridTableStyle^ myTableStyle;
   for ( __int32 i = 0; i < grid->TableStyles->Count; i++ )
   {
      myTableStyle = grid->TableStyles[ i ];
      myColumns = myTableStyle->GridColumnStyles;
      
      /* Iterate through the collection and print each 
               object's type and width. */
      DataGridColumnStyle^ dgCol;
      for ( __int32 j = 0; j < myColumns->Count; j++ )
      {
         dgCol = myColumns[ j ];
         Console::WriteLine( dgCol->MappingName );
         Console::WriteLine( dgCol->GetType()->ToString() );
         Console::WriteLine( dgCol->Width );

      }

   }
}

private void PrintColumnInformation(DataGrid grid){
   Console.WriteLine("Count: " + grid.TableStyles.Count);
   GridColumnStylesCollection myColumns;   
   foreach(DataGridTableStyle myTableStyle in grid.TableStyles){

      myColumns = myTableStyle.GridColumnStyles;

      /* Iterate through the collection and print each 
      object's type and width. */
      foreach (DataGridColumnStyle dgCol in myColumns){
         Console.WriteLine(dgCol.MappingName);
         Console.WriteLine(dgCol.GetType().ToString());
         Console.WriteLine(dgCol.Width);
      }
   }

Private Sub PrintColumnInformation(grid as DataGrid)
   Console.WriteLine("Count: " & grid.TableStyles.Count)
   Dim myTableStyle As DataGridTableStyle
   Dim myColumns As GridColumnStylesCollection
   Dim dgCol As DataGridColumnStyle
   For Each myTableStyle in grid.TableStyles
      myColumns = myTableStyle.GridColumnStyles

      ' object's type and width.
      For Each dgCol in myColumns
