示例

下面的代码示例演示如何使用此类型。The following code example illustrates the use of this type. 有关详细信息,请参阅如何:根据 Windows 窗体 DataGridView 控件中的单元格的更改执行自定义操作。For more information, see How to: Perform a Custom Action Based on Changes in a Cell of a Windows Forms DataGridView Control.

private void dataGridView1_CellStateChanged(object sender,
    DataGridViewCellStateChangedEventArgs e)
{
    DataGridViewElementStates state = e.StateChanged;
    string msg = String.Format("Row {0}, Column {1}, {2}",
        e.Cell.RowIndex, e.Cell.ColumnIndex, e.StateChanged);
    MessageBox.Show(msg, "Cell State Changed");
}
Private Sub dataGridView1_CellStateChanged(ByVal sender As Object, _
    ByVal e As DataGridViewCellStateChangedEventArgs) _
    Handles dataGridView1.CellStateChanged

    Dim state As DataGridViewElementStates = e.StateChanged
    Dim msg As String = String.Format( _
        "Row {0}, Column {1}, {2}", _
        e.Cell.RowIndex, e.Cell.ColumnIndex, e.StateChanged)

注解

尽管这些不同状态 (如冻结) 由 UI 强制执行, 但它们可以以编程方式无效。Although these different states, like Frozen, are enforced by the UI, they can be programmatically overruled.
