Exemples

L’exemple de code suivant montre comment définir les propriétés ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount et MultiSelect.The following code example demonstrates how to set the ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, and MultiSelect properties. En outre, l’exemple de code montre comment définir les propriétés DataGridViewColumn.Name et DataGridViewColumn.DefaultCellStyle.In addition, the code example demonstrates how to set the DataGridViewColumn.Name and DataGridViewColumn.DefaultCellStyle properties. Pour exécuter cet exemple, collez le code dans un formulaire qui contient un DataGridView nommé dataGridView1, puis appelez la méthode SetUpDataGridView à partir du constructeur du formulaire ou du gestionnaire d’événements Load.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. Vérifiez que tous les événements sont associés à leurs gestionnaires d’événements.Ensure all events are associated with their event handlers.

Remarques

Si la propriété ColumnHeadersBorderStyle a une valeur autre que Single, la propriété GridColor doit être une couleur système.If the ColumnHeadersBorderStyle property is set to anything other than Single, the GridColor property must be a system color.

Vous ne pouvez pas définir cette propriété sur la valeur Custom, qui est une valeur en lecture seule indiquant que le style de bordure a été personnalisé à l’aide de la propriété AdvancedColumnHeadersBorderStyle.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.

Notes

Si les styles visuels sont activés pour l’application à l’aide de la méthode Application.EnableVisualStyles et que la propriété EnableHeadersVisualStyles est true, les en-têtes de colonnes sont peints à l’aide du thème actuel.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. Dans ce cas, la valeur de la propriété ColumnHeadersBorderStyle est ignorée pour tous les en-têtes de colonne, à l’exception de la TopLeftHeaderCell, à laquelle le thème n’est pas appliqué.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.
