Return Value

true if the collection contains the DataGridColumnStyle; otherwise, false.

Use the Contains method to determine if a particular DataGridColumnStyle exists before invoking the Remove method to remove the item. If you need to know the index of a particular DataGridColumnStyle, use the IndexOf method.

The following code example uses the Contains method to determine if a GridColumnStylesCollection contains a specific DataGridColumnStyle.

Private Sub ContainsThisDataCol()
   Dim myGridColumnCol As GridColumnStylesCollection
   myGridColumnCol = dataGrid1.TableStyles(0).GridColumnStyles
   ' Get the CurrencyManager for the table you want to add a column to.
   Dim myCurrencyManager As CurrencyManager = _
   CType(Me.BindingContext(ds.Tables("Suppliers")), CurrencyManager)
   ' Get the PropertyDescriptor for the DataColumn of the new column.
   Dim pd As PropertyDescriptor = _
   Dim myColumn As New DataGridTextBoxColumn()
   myColumn.PropertyDescriptor = pd
   ' Test to see if the present columns contains the new object.
   Console.WriteLine(DataGrid1.TableStyles(0).GridColumnStyles. _
End Sub
