DataGridView.CellLeave 事件

定義

儲存格失去輸入焦點且不再是目前儲存格時發生。Occurs when a cell loses input focus and is no longer the current cell.

public:
 event System::Windows::Forms::DataGridViewCellEventHandler ^ CellLeave;
public event System.Windows.Forms.DataGridViewCellEventHandler CellLeave;
member this.CellLeave : System.Windows.Forms.DataGridViewCellEventHandler 
Public Custom Event CellLeave As DataGridViewCellEventHandler 

範例

下列程式碼範例說明如何處理這個事件,以變更目前儲存格的 SelectionBackColor 屬性。The following code example illustrates how to handle this event to change the SelectionBackColor property of the current cell. 在此範例中,選取範圍背景色彩會在 CellEnter 事件中設定,然後在 CellLeave 事件上重設為 EmptyIn this example the selection background color is set in the CellEnter event, then reset to Empty on the CellLeave event. 若要執行此範例,請將程式碼貼入包含名為 dataGridView1DataGridView 的表單中,並確定所有事件都與事件處理常式相關聯。To run this example, paste the code into a form that contains a DataGridView named dataGridView1 and ensure that all events are associated with their event handlers.

private void dataGridView1_CellEnter(object sender, 
    DataGridViewCellEventArgs e)
{
    dataGridView1[e.ColumnIndex, e.RowIndex].Style
        .SelectionBackColor = Color.Blue;
}

private void dataGridView1_CellLeave(object sender, 
    DataGridViewCellEventArgs e)
{
    dataGridView1[e.ColumnIndex, e.RowIndex].Style
        .SelectionBackColor = Color.Empty;
}
Private Sub dataGridView1_CellEnter(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.CellEnter

    dataGridView1(e.ColumnIndex, e.RowIndex).Style _
        .SelectionBackColor = Color.Blue

End Sub

Private Sub dataGridView1_CellLeave(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.CellLeave

    dataGridView1(e.ColumnIndex, e.RowIndex).Style _
        .SelectionBackColor = Color.Empty

End Sub
