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)
MessageBox.Show(msg, "Cell State Changed")
End Sub
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.
