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 @no__t。The following code example illustrates how to handle this event to change the SelectionBackColor property of the current cell. 在此示例中,选择背景色在 CellEnter 事件中设置,然后重置为 CellLeave 事件上的 @no__t。In 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 @no__t 的 @no__t 0 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
