Examples

The following code example prints information about each DataGridColumnStyle in a 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
   
      ' Iterate through the collection and print each 
      ' object's type and width.
      For Each dgCol in myColumns
         Console.WriteLine(dgCol.MappingName)
         Console.WriteLine(dgCol.GetType.ToString())
         Console.WriteLine(dgCol.Width)
      Next
   Next
End Sub

Remarks

On the DataGridTableStyle, you access the GridColumnStylesCollection through the GridColumnStyles property.

The GridColumnStylesCollection uses standard Add and Remove methods to manipulate the collection.

Use the Contains method to determine if a specific property value exists in the collection. Additionally, use the IndexOf method to determine the index of any DataGridColumnStyle object within the collection.

Caution

Always create DataGridColumnStyle objects and add them to the GridColumnStylesCollection before adding DataGridTableStyle objects to the GridTableStylesCollection. When you add an empty DataGridTableStyle with a valid MappingName value to the collection, DataGridColumnStyle objects are automatically generated for you. Consequently, an exception will be thrown if you try to add new DataGridColumnStyle objects with duplicate MappingName values to the GridColumnStylesCollection.

Properties

Count	Gets the total number of elements in the collection. (Inherited from BaseCollection)
IsReadOnly	Gets a value indicating whether the collection is read-only. (Inherited from BaseCollection)
IsSynchronized	Gets a value indicating whether access to the ICollection is synchronized. (Inherited from BaseCollection)
Item[Int32]	Gets the DataGridColumnStyle at a specified index.
Item[PropertyDescriptor]	Gets the DataGridColumnStyle associated with the specified PropertyDescriptor.
Item[String]	Gets the DataGridColumnStyle with the specified name.
List	Gets the list of items in the collection.
SyncRoot	Gets an object that can be used to synchronize access to the BaseCollection. (Inherited from BaseCollection)

Methods

GetType()	Gets the Type of the current instance. (Inherited from Object)
IndexOf(DataGridColumnStyle)	Gets the index of a specified DataGridColumnStyle.
InitializeLifetimeService()	Obsolete. Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject)
OnCollectionChanged(CollectionChangeEventArgs)	Raises the CollectionChanged event.
