Przykłady

Poniższy przykład kodu demonstruje, jak ustawić ColumnHeadersDefaultCellStyle właściwości,,,,,,,, AutoSizeRowsMode ColumnHeadersBorderStyle CellBorderStyle GridColor BackgroundColor RowHeadersVisible SelectionMode ColumnCount i MultiSelect .The following code example demonstrates how to set the ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, and MultiSelect properties. Ponadto w przykładzie kodu pokazano, jak ustawić DataGridViewColumn.Name DataGridViewColumn.DefaultCellStyle właściwości i.In addition, the code example demonstrates how to set the DataGridViewColumn.Name and DataGridViewColumn.DefaultCellStyle properties. Aby uruchomić ten przykład, wklej kod do formularza, który zawiera DataGridView nazwę dataGridView1 , a następnie Wywołaj SetUpDataGridView metodę z konstruktora lub Load procedury obsługi zdarzeń.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. Upewnij się, że wszystkie zdarzenia są skojarzone z ich obsługą zdarzeń.Ensure all events are associated with their event handlers.

Uwagi

Jeśli ColumnHeadersBorderStyle Właściwość jest ustawiona na coś innego niż Single , GridColor Właściwość musi być kolorem systemu.If the ColumnHeadersBorderStyle property is set to anything other than Single, the GridColor property must be a system color.

Nie można ustawić tej właściwości na Custom wartość, która jest wartością tylko do odczytu wskazującą, że styl obramowania został dostosowany przy użyciu AdvancedColumnHeadersBorderStyle właściwości.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.

Uwaga

Jeśli style wizualizacji są włączone dla aplikacji za pośrednictwem Application.EnableVisualStyles metody, a EnableHeadersVisualStyles Właściwość jest true , nagłówki kolumn są rysowane przy użyciu bieżącego motywu.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. W takim przypadku wartość ColumnHeadersBorderStyle właściwości jest ignorowana dla wszystkich nagłówków kolumn z wyjątkiem TopLeftHeaderCell , do których motyw nie jest stosowany.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.
