public:
 property bool RowHeadersVisible { bool get(); void set(bool value); };
public bool RowHeadersVisible { get; set; }
member this.RowHeadersVisible : bool with get, set
Public Property RowHeadersVisible As Boolean

Eigenschaftswert

true , wenn die Spalte angezeigt wird, die die Zeilenheader enthält, andernfalls false.true if the column that contains row headers is displayed; otherwise, false. Die Standardeinstellung ist true.The default is true.

Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie die ColumnHeadersDefaultCellStyleEigenschaften AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, und MultiSelect festgelegt werden.The following code example demonstrates how to set the ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, and MultiSelect properties. Außerdem wird im Codebeispiel veranschaulicht, wie die-Eigenschaft DataGridViewColumn.Name und DataGridViewColumn.DefaultCellStyle die-Eigenschaft festgelegt werden.In addition, the code example demonstrates how to set the DataGridViewColumn.Name and DataGridViewColumn.DefaultCellStyle properties. Um dieses Beispiel auszuführen, fügen Sie den Code in ein Formular ein, DataGridView das dataGridView1einen mit dem Namen enthält SetUpDataGridView , und dann die-Methode aus dem Load Konstruktor oder Ereignishandler des Formulars.To run this example, paste the code into a form that contains a DataGridView named dataGridView1, and then call the SetUpDataGridView method from the form's constructor or Load event handler. Stellen Sie sicher, dass alle Ereignisse ihren Ereignis Handlern zugeordnet sind.Ensure all events are associated with their event handlers.

Hinweise

Wenn die RowHeadersVisible -Eigenschaft falseist, kann die Resizable Größe einer Zeile, true deren-Eigenschaft auf festgelegt ist, in der Benutzeroberfläche immer noch geändert werden, indem Sie auf den Mauszeiger an einer beliebigen Stelle entlang des unteren Rands der Zeile klicken, um die Größe zu ändern.If the RowHeadersVisible property is false, a row whose Resizable property is set to true can still be resized in the user interface (UI) by clicking the mouse cursor anywhere along the bottom border of the row to be resized.
