DataGridTextBoxColumn-Konstruktor (PropertyDescriptor)

Initialisiert eine neue Instanz einer DataGridTextBoxColumn mit einem angegebenen PropertyDescriptor.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

Syntax

'Declaration
Public Sub New ( _
    prop As PropertyDescriptor _
)
'Usage
Dim prop As PropertyDescriptor

Dim instance As New DataGridTextBoxColumn(prop)

public DataGridTextBoxColumn (
    PropertyDescriptor prop
)

public:
DataGridTextBoxColumn (
    PropertyDescriptor^ prop
)

public DataGridTextBoxColumn (
    PropertyDescriptor prop
)

public function DataGridTextBoxColumn (
    prop : PropertyDescriptor
)

Parameter

Hinweise

Der DataGridColumnStyle verwendet einen PropertyDescriptor, um den Typ der Daten zu bestimmen, die in der Spalte angezeigt werden. Verwenden Sie die GetItemProperties-Methode der BindingManagerBase-Klasse, um eine PropertyDescriptorCollection zurückzugeben.

Beispiel

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

Private Sub AddColumn(myTable As DataTable)
    ' Add a new DataColumn to the DataTable.
    Dim myColumn As New DataColumn("myTextBoxColumn")
    myColumn.DataType = GetType(String)
    myColumn.DefaultValue = "default string"
    myTable.Columns.Add(myColumn)
    ' Get the ListManager for the DataTable.
    Dim cm As CurrencyManager = CType(Me.BindingContext(myTable), CurrencyManager)
    ' Use the ListManager to get the PropertyDescriptor for the new column.
    Dim pd As PropertyDescriptor = cm.GetItemProperties()("myTextBoxColumn")
    ' Create a new DataTimeFormat object.
    Dim fmt As New DateTimeFormatInfo()
    ' Insert code to set format.
    Dim myColumnTextColumn As DataGridTextBoxColumn
    ' Create the DataGridTextBoxColumn with the PropertyDescriptor and Format.
    myColumnTextColumn = New DataGridTextBoxColumn(pd, fmt.SortableDateTimePattern)
    ' Add the new DataGridColumnStyle to the GridColumnsCollection.
    dataGrid1.TableStyles(0).GridColumnStyles.Add(myColumnTextColumn)
End Sub 'AddColumn

private void AddColumn(DataTable myTable){
    // Add a new DataColumn to the DataTable.
    DataColumn myColumn = new DataColumn("myTextBoxColumn");

    // Get the ListManager for the DataTable.
    CurrencyManager cm = (CurrencyManager)this.BindingContext[myTable];
    // Use the ListManager to get the PropertyDescriptor for the new column.

   }
