Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie die ColumnHeadersDefaultCellStyleEigenschaften , AutoSizeRowsMode, , ColumnHeadersBorderStyle, BackgroundColorGridColorRowHeadersVisibleCellBorderStyle, SelectionModeund ColumnCountMultiSelect Eigenschaften festgelegt werden. Darüber hinaus veranschaulicht das Codebeispiel, wie die DataGridViewColumn.Name Eigenschaften festgelegt werden DataGridViewColumn.DefaultCellStyle . Zum Ausführen dieses Beispiels fügen Sie den Code in ein Formular ein, das einen DataGridView benannten dataGridView1Namen enthält, und rufen Sie dann die SetUpDataGridView Methode aus dem Konstruktor oder Load Ereignishandler des Formulars auf. Stellen Sie sicher, dass alle Ereignisse ihren Ereignishandlern zugeordnet sind.

   style->Font = gcnew System::Drawing::Font( dataGridView1->Font,FontStyle::Bold );

   dataGridView1->Name = "dataGridView1";
   dataGridView1->Location = Point(8,8);
