DataGridView.RowLeave 事件

定義

資料列失去輸入焦點且不再是目前資料列時發生。Occurs when a row loses input focus and is no longer the current row.

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

範例

下列程式碼範例說明如何處理這個事件,以變更目前資料列中儲存格的 BackColor 屬性。The following code example illustrates how to handle this event to change the BackColor property of the cells in the current row. 在此範例中,背景色彩會在 RowEnter 事件中設定,然後在 RowLeave 事件上重設為 EmptyIn this example, the background color is set in the RowEnter event, then reset to Empty on the RowLeave 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_RowEnter(object sender, 
    DataGridViewCellEventArgs e)
{
    for (int i = 0; i < dataGridView1.Rows[e.RowIndex].Cells.Count; i++)
    {
        dataGridView1[i, e.RowIndex].Style.BackColor = Color.Yellow;
    }
}

private void dataGridView1_RowLeave(object sender, 
    DataGridViewCellEventArgs e)
{
    for (int i = 0; i < dataGridView1.Rows[e.RowIndex].Cells.Count; i++)
    {
        dataGridView1[i, e.RowIndex].Style.BackColor = Color.Empty;
    }
}
Private Sub dataGridView1_RowEnter(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.RowEnter

    Dim i As Integer
    For i = 0 To dataGridView1.Rows(e.RowIndex).Cells.Count - 1
        dataGridView1(i, e.RowIndex).Style _
            .BackColor = Color.Yellow
    Next i

End Sub

Private Sub dataGridView1_RowLeave(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.RowLeave

    Dim i As Integer
    For i = 0 To dataGridView1.Rows(e.RowIndex).Cells.Count - 1
        dataGridView1(i, e.RowIndex).Style _
            .BackColor = Color.Empty
    Next i

End Sub
