DataGridTableStyle.RowHeadersVisible-Eigenschaft

Ruft einen Wert ab, der angibt, ob die Zeilenköpfe sichtbar sind, oder legt diesen fest.

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

Syntax

'Declaration
Public Property RowHeadersVisible As Boolean
'Usage
Dim instance As DataGridTableStyle
Dim value As Boolean

value = instance.RowHeadersVisible

instance.RowHeadersVisible = value

public bool RowHeadersVisible { get; set; }

public:
property bool RowHeadersVisible {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_RowHeadersVisible ()

/** @property */
public void set_RowHeadersVisible (boolean value)

public function get RowHeadersVisible () : boolean

public function set RowHeadersVisible (value : boolean)

Eigenschaftenwert

true, wenn die Zeilenköpfe sichtbar sind, andernfalls false. Der Standardwert ist true.

Hinweise

Wenn die Zeilenköpfe sichtbar sind, wird in jedem Zeilenkopf ein Pluszeichen angezeigt, wenn die zugrunde liegende DataTable eine verknüpfte untergeordnete Tabelle besitzt.

Diese Eigenschaft hat erst dann eine Funktion, wenn Sie der GridTableStylesCollectionDataGridTableStyle-Objekte hinzufügt haben. Vorher hat das Festlegen dieser Eigenschaft keine Auswirkungen.
