Winforms组合框-直接设置值

我了解了如何在datagrid视图中将事件添加到我的组合框中：

    private void dataGridViewCaseObjects_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        var combo = e.Control as ComboBox;
        if (combo != null)
        {
            combo.SelectedIndexChanged -= ComboBox_SelectedIndexChanged;
            combo.SelectedIndexChanged += ComboBox_SelectedIndexChanged;
        }
    }

    private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
    {
        // Actually commit the selected string to combobox 
    }

---

如何从此时开始强制提交到组合框？

强制提交？如果您在indexchanged方法中检查combobox的值，您将获得所选字符串。请清楚地描述您想要的内容。是否要将所选文本发送到其他位置，例如另一个控件？
