Beispiel

Im folgenden Beispiel wird eine DataGridTextBoxColumn erstellt und der GridColumnStylesCollection hinzugefügt.

Private Sub AddColumn()
    Dim myTable As New DataTable()
    
    ' Add a new DataColumn to the DataTable.
    Dim myColumn As New DataColumn("myTextBoxColumn")
    myColumn.DataType = System.Type.GetType("System.String")
    myColumn.DefaultValue = "default string"
    myTable.Columns.Add(myColumn)
    ' Get the CurrencyManager for the DataTable.
    Dim cm As CurrencyManager = CType(Me.BindingContext(myTable), CurrencyManager)
    ' Use the CurrencyManager to get the PropertyDescriptor for the new column.
