datagridviewcombobox事件处理程序问题

我有一个问题的处理索引更改的事件为一个comboBox驻留在一个dataGridView。我写了一个方法来处理comboBox的选择变化使用委托:

ComboBox.SelectedIndexChanged -= delegate { ComboBoxIndexChanged(); };
ComboBox.SelectedIndexChanged += delegate { ComboBoxIndexChanged(); };

或eventandler:

comboBox.SelectedIndexChanged += new EventHandler(ComboBoxIndexChanged);

，但这两种方法都不像预期的那样工作。也就是说，当你点击你的选择在comboBox(包含在dataGridView)，它需要多次点击导致我的ComboBoxIndexChanged();方法的正确运作，如果它决定运作。什么是最好的方法来克服/去指定一个事件indexedChange的组合框在一个dataGridView?

我目前在上下文中使用的代码如下:

private void dataGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    try
    {
        if (this.dataGridView.CurrentCell.ColumnIndex == (int)Column.Col)
        {
            ComboBox comboBox = e.Control as ComboBox;
            if (comboBox != null)
            {
                comboBox.SelectedIndexChanged += new EventHandler(ComboBoxIndexChanged);
            }
        }
        return;
    }
    catch (Exception Ex)
    {
        Utils.ErrMsg(Ex.Message);
        return;
    }
}

和ComboBoxIndexChanged事件为:

private void ComboBoxIndexChanged(object sender, EventArgs e)
{
    // Do some amazing stuff...
}

我在StackOverFlow上读过一个类似的线程，其中指出以这种方式处理comboBox更改事件存在问题，但我无法得到解决方案。这篇文章可以在这里找到:SelectedIndexChanged"Datagridview上的ComboBoxColumn中的事件。它说:

"事情变得复杂，因为他们优化了DataGridView只有一个编辑控件的所有行。下面是我处理类似情况的方法:

首先连接一个委托到editcontrolshow事件:

myGrid.EditingControlShowing += new DataGridViewEditingControlShowingEventHandler(
                                Grid_EditingControlShowing);
...

然后在处理程序中，连接到EditControl的SelectedValueChanged事件:

void Grid_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    ComboBox combo = e.Control as ComboBox;
    if (combo != null)
    {
        // the event to handle combo changes
        EventHandler comboDelegate = new EventHandler(
          (cbSender, args) =>
            {
                DoSomeStuff();
            });
        // register the event with the editing control
        combo.SelectedValueChanged += comboDelegate;
        // since we don't want to add this event multiple times, when the 
        // editing control is hidden, we must remove the handler we added.
        EventHandler visibilityDelegate = null;
        visibilityDelegate = new EventHandler(
          (visSender, args) =>
            {
                // remove the handlers when the editing control is
                // no longer visible.
                if ((visSender as Control).Visible == false)
                {
                    combo.SelectedValueChanged -= comboDelegate;
                    visSender.VisibleChanged -= visibilityDelegate;
                }
            });
         (sender as DataGridView).EditingControl.VisibleChanged += 
           visibilityDelegate;
    }
}"

我遇到的这个问题是"VisSender"没有定义，因此事件"visblechanged"不能使用。

小伙子们的任何帮助，我总是非常感激。

// This event handler manually raises the CellValueChanged event
// by calling the CommitEdit method.
void dataGridView1_CurrentCellDirtyStateChanged(object sender,
    EventArgs e)
{
    if (dataGridView1.IsCurrentCellDirty)
    {
        dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
    }
}
