プロパティ値

属性

例外

このプロパティの設定時に指定した値が、有効な DataGridViewHeaderBorderStyle 値ではありません。The specified value when setting this property is not a valid DataGridViewHeaderBorderStyle value.

このプロパティの設定時に指定された値が Custom です。The specified value when setting this property is Custom.

次のコード例は、ColumnHeadersDefaultCellStyleAutoSizeRowsModeColumnHeadersBorderStyleCellBorderStyleGridColorBackgroundColorRowHeadersVisibleSelectionModeColumnCount、および MultiSelect の各プロパティを設定する方法を示しています。The following code example demonstrates how to set the ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, and MultiSelect properties. また、このコード例では、DataGridViewColumn.Name および DataGridViewColumn.DefaultCellStyle プロパティを設定する方法を示しています。In addition, the code example demonstrates how to set the DataGridViewColumn.Name and DataGridViewColumn.DefaultCellStyle properties. この例を実行するには、@ no__t-1 という名前の @no__t 0 を含むフォームにコードを貼り付けてから、フォームのコンストラクターまたは Load イベントハンドラーから @no__t の2つのメソッドを呼び出します。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. すべてのイベントがイベントハンドラーに関連付けられていることを確認します。Ensure all events are associated with their event handlers.

注釈

@No__t-0 プロパティが Single 以外の値に設定されている場合、GridColor プロパティはシステムカラーである必要があります。If the ColumnHeadersBorderStyle property is set to anything other than Single, the GridColor property must be a system color.

このプロパティを @no__t 0 の値に設定することはできません。この値は、AdvancedColumnHeadersBorderStyle プロパティを使用して境界線スタイルがカスタマイズされていることを示す読み取り専用の値です。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.

注意

@No__t-0 メソッドを使用してアプリケーションに対して visual スタイルが有効になっていて、EnableHeadersVisualStyles プロパティが true の場合、列ヘッダーは現在のテーマを使用して描画されます。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. この場合、テーマが適用されていない TopLeftHeaderCell を除くすべての列ヘッダーに対して、ColumnHeadersBorderStyle プロパティの値は無視されます。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.
