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 dasdataGridView1einen 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 nameddataGridView1, 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 ColumnHeadersBorderStyle -Eigenschaft auf einen anderen Wert als Singlefestgelegt GridColor ist, muss die-Eigenschaft eine System Farbe sein.If the ColumnHeadersBorderStyle property is set to anything other than Single, the GridColor property must be a system color.

Diese Eigenschaft kann nicht auf den Custom Wert festgelegt werden. dabei handelt es sich um einen schreibgeschützten Wert, der angibt, dass die Rahmenart durch die Verwendung AdvancedColumnHeadersBorderStyle der-Eigenschaft angepasst wurde.You cannot set this property to the Custom value, which is a read-only value indicating that the border style has been customized through the use of the AdvancedColumnHeadersBorderStyle property.

Hinweis

Wenn visuelle Stile für die Anwendung über die Application.EnableVisualStyles -Methode aktiviert sind und die EnableHeadersVisualStyles - trueEigenschaft ist, werden die Spaltenheader mit dem aktuellen Design gezeichnet.If visual styles are enabled for the application through the Application.EnableVisualStyles method and the EnableHeadersVisualStyles property is true, the column headers are painted using the current theme. In diesem Fall wird der Wert der ColumnHeadersBorderStyle -Eigenschaft für alle Spaltenheader außer der TopLeftHeaderCellignoriert, auf die das Design nicht angewendet wird.In this case, the value of the ColumnHeadersBorderStyle property is ignored for all column headers except the TopLeftHeaderCell, to which the theme is not applied.
