如何：根据 Windows 窗体 DataGridView 控件的单元格中的更改执行自定义操作

  • 项目

DataGridView 控件包含许多可用于检测 DataGridView 单元格状态更改的事件。 最常用的两个事件是 CellValueChanged 和 CellStateChanged 事件。

检测 DataGridView 单元格的值更改

  • 为 CellValueChanged 事件编写处理程序。

    private void dataGridView1_CellValueChanged(object sender,
    DataGridViewCellEventArgs e)
{
    string msg = String.Format(
        "Cell at row {0}, column {1} value changed",
        e.RowIndex, e.ColumnIndex);
    MessageBox.Show(msg, "Cell Value Changed");
}

    Private Sub dataGridView1_CellValueChanged(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.CellValueChanged

    Dim msg As String = String.Format( _
        "Cell at row {0}, column {1} value changed", _
        e.RowIndex, e.ColumnIndex)
    MessageBox.Show(msg, "Cell Value Changed")

End Sub

检测 DataGridView 单元格的状态更改

  • 为 CellStateChanged 事件编写处理程序。

    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
