Wartość właściwości

DataGridViewCellStyle

DataGridViewCellStyleReprezentuje styl domyślny stosowany do komórek nagłówka wiersza.The DataGridViewCellStyle that represents the default style applied to the row header cells.

Przykłady

Poniższy przykład kodu ilustruje sposób używania tej właściwości w DataGridView z kolorami niestandardowymi.The following code example illustrates how to use this property in a DataGridView with custom colors. Zwróć uwagę DataGridViewCellStyle.SelectionBackColor , jak właściwość jest ustawiona na Color.Empty tak, aby wartość była dziedziczona z DefaultCellStyle obiektu.Note how the DataGridViewCellStyle.SelectionBackColor property is set to Color.Empty so that the value is inherited from the DefaultCellStyle object.

Ten przykład jest częścią większego przykładu dostępnego w DataGridViewCellStyle przeglądzie klasy.This example is part of a larger example provided in the DataGridViewCellStyle class overview.

// Configures the appearance and behavior of a DataGridView control.

Uwagi

Wartość domyślna DataGridViewCellStyle zwracana przez tę właściwość ma następujące początkowe wartości właściwości.The default DataGridViewCellStyle returned by this property has the following initial property values.

Właściwość DataGridViewCellStyleDataGridViewCellStyle property Wartość domyślnaDefault value
BackColor Wartość SystemBrushes.Control właściwości.The value of the SystemBrushes.Control property.
ForeColor Wartość SystemBrushes.WindowText właściwości.The value of the SystemBrushes.WindowText property.
SelectionBackColor Wartość SystemBrushes.Highlight właściwości.The value of the SystemBrushes.Highlight property.
SelectionForeColor Wartość SystemBrushes.HighlightText właściwości.The value of the SystemBrushes.HighlightText property.
Font Wartość Font właściwości.The value of the Font property.
Alignment DataGridViewContentAlignment.MiddleLeft
WrapMode DataGridViewTriState.True

Te wartości automatycznie przesłaniają wartości ustawione za pomocą DefaultCellStyle właściwości.These values automatically override the values set through the DefaultCellStyle property. Aby wymusić, aby nagłówki wierszy dziedziczyły DefaultCellStyle wartości, musisz ustawić wartości domyślne w RowHeadersDefaultCellStyle obiekcie na wartość domyślną wskazywaną dla DataGridViewCellStyle klasy.To force row headers to inherit the DefaultCellStyle values, you must set the values in the RowHeadersDefaultCellStyle object to the default values indicated for the DataGridViewCellStyle class.
