範例

下列程式碼範例示範如何設定 ColumnHeadersDefaultCellStyleAutoSizeRowsModeColumnHeadersBorderStyleCellBorderStyleGridColorBackgroundColorRowHeadersVisibleSelectionModeColumnCountMultiSelect 屬性。The following code example demonstrates how to set the ColumnHeadersDefaultCellStyle, AutoSizeRowsMode, ColumnHeadersBorderStyle, CellBorderStyle, GridColor, BackgroundColor, RowHeadersVisible, SelectionMode, ColumnCount, and MultiSelect properties. 此外,此程式碼範例會示範如何設定 DataGridViewColumn.Name 和 @no__t 1 屬性。In addition, the code example demonstrates how to set the DataGridViewColumn.Name and DataGridViewColumn.DefaultCellStyle properties. 若要執行此範例,請將程式碼貼入包含名為 @no__t 的 @no__t 0 的表單中,然後從表單的程式碼,或 Load 事件處理常式中呼叫 SetUpDataGridView 方法。To run this example, paste the code into a form that contains a DataGridView named dataGridView1, and then call the SetUpDataGridView method from the form's constructor or Load event handler. 請確定所有事件都與事件處理常式相關聯。Ensure all events are associated with their event handlers.
