DataGridView.CellLeave 事件

定义

单元格失去输入焦点并且不再是当前单元格时发生。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 

示例

下面的代码示例演示如何处理此事件以更改当前单元格的 SelectionBackColor 属性。The following code example illustrates how to handle this event to change the SelectionBackColor property of the current cell. 在此示例中,将在 CellEnter 事件中设置选择背景颜色,然后重置为 CellLeave 事件 EmptyIn this example the selection background color is set in the CellEnter event, then reset to Empty on the CellLeave event. 若要运行此示例,请将代码粘贴到包含名为 dataGridView1DataGridView 的窗体中,并确保所有事件都与它们的事件处理程序相关联。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
