检测form内，数据变动

[gadev]

可以一个一个判断textchanged,
有没简单一点的方法检测form内，数据变动, 包括datagridview控件

请教
谢谢

把所有需要监测的控件属性CausesValidation设置为true.
然后挂接Form.Validating事件.........

Sorry, it does not work to sink to the form's Validating event.
There is a thread on http://bytes.com/groups/net-vb/362101-how-does-validation-work-winforms discussing the firing of form's Validating event, however, no conlusion was get there.

My next solution would be something like below, however, it's poor anyway, waiting for gurus...

protected override void OnLoad(EventArgs e) {
            base.OnLoad(e);
            foreach (Control control in Controls) {
                if(control.CausesValidation) {
                    control.Validating += new CancelEventHandler(control_Validating);
                }
            }
        }

        void control_Validating(object sender, CancelEventArgs e)
        {
            Console.WriteLine(sender);
        }

定义一个对象 保存副本 将对象与控件数据源绑定 控件数据发生异动后 将对象与副本对比
