DataGridView.CellEndEdit 事件

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

当前选定单元格的编辑模式停止时发生。

public:
 event System::Windows::Forms::DataGridViewCellEventHandler ^ CellEndEdit;

public event System.Windows.Forms.DataGridViewCellEventHandler CellEndEdit;

member this.CellEndEdit : System.Windows.Forms.DataGridViewCellEventHandler 

Public Custom Event CellEndEdit As DataGridViewCellEventHandler 

事件类型

DataGridViewCellEventHandler

示例

下面的代码示例演示了如何处理此事件以清除行 DataGridViewRow.ErrorText 属性，以防它以前由 CellValidating 事件处理程序设置。 CellValidating当新单元格值满足验证条件时，事件处理程序可以清除错误文本，但当用户通过按 ESC 还原到旧单元格值时，CellValidating事件不会发生。 此示例是演练：验证 Windows 窗体 DataGridView 控件中的数据中提供的更大示例的一部分。

private void dataGridView1_CellValidating(object sender,
    DataGridViewCellValidatingEventArgs e)
{
    string headerText = 
        dataGridView1.Columns[e.ColumnIndex].HeaderText;

    // Abort validation if cell is not in the CompanyName column.
    if (!headerText.Equals("CompanyName")) return;

    // Confirm that the cell is not empty.
    if (string.IsNullOrEmpty(e.FormattedValue.ToString()))
    {
        dataGridView1.Rows[e.RowIndex].ErrorText =
            "Company Name must not be empty";
        e.Cancel = true;
    }
}

void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    // Clear the row error in case the user presses ESC.   
    dataGridView1.Rows[e.RowIndex].ErrorText = String.Empty;
}

Private Sub dataGridView1_CellValidating(ByVal sender As Object, _
    ByVal e As DataGridViewCellValidatingEventArgs) _
    Handles dataGridView1.CellValidating

    Dim headerText As String = _
        dataGridView1.Columns(e.ColumnIndex).HeaderText

    ' Abort validation if cell is not in the CompanyName column.
    If Not headerText.Equals("CompanyName") Then Return

    ' Confirm that the cell is not empty.
    If (String.IsNullOrEmpty(e.FormattedValue.ToString())) Then
        dataGridView1.Rows(e.RowIndex).ErrorText = _
            "Company Name must not be empty"
        e.Cancel = True
    End If
End Sub

Private Sub dataGridView1_CellEndEdit(ByVal sender As Object, _
    ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
    Handles dataGridView1.CellEndEdit

    ' Clear the row error in case the user presses ESC.   
    dataGridView1.Rows(e.RowIndex).ErrorText = String.Empty

End Sub
