C#数据绑定Windows窗体控件不保留值,除非您离开该字段

但这并不能完全回答我的问题.我有同样的情况.在ToolStrip_click上,我看过我的所有控件,并强制执行“WriteValue()”,但是在保存之前仍会恢复到之前的值.任何人都可以建议我如何解决这个问题？我是否执行不正确？

(请参阅当前(非工作)解决方案的代码.)

private void menuStrip1_ItemClicked(object sender,ToolStripItemClickedEventArgs e)
{
    // Make sure that all items have updated databindings.
    foreach (Control C in this.Controls)
    {
        foreach (Binding b in C.DataBindings)
        {
            // Help: this doesn't seem to be working.
            b.WriteValue();
        }
    }
}

该代码现在要简单得多,但这是一个相当的黑客.我会很高兴知道是否有更“正确”的解决方案.

private void menuStrip1_ItemClicked(object sender,ToolStripItemClickedEventArgs e)
{
    // Make sure that all text fields have updated by forcing everything
    // to lose focus except this lonely little label.
    label44.Focus();
}
