事件被触发之前，我如何确定DataGrid是否已排序或分页？ [英] How can I determine if a DataGrid has been sorted or paged, prior to the events being triggered?

问题描述

我有一个 DataGrid 具有绑定到 SortCommand 和 PageIndexChanged 。如何确定这些事件处理程序是否即将被调用，比如page_load？

I have a DataGrid that has event handlers bound to SortCommand and PageIndexChanged. How can I determine if those event handlers are about to be called, say on page_load?

这些事件在page_load之后会很好地启动，但是我想知道page_load如果它们被触发。

These events will fire just fine after page_load, but I'd like to know at page_load if they are to be fired.

推荐答案

Request.Form [__ EVENTTARGET] 和 Request.Form [__ EVENTARGUMENT] 将给出导致返回的对象和事件参数。如果数据网格不会导致回发，那么在帖子中可能会有一个值。使用Fiddler查看点击按钮时发送的请求。

Request.Form["__EVENTTARGET"] and Request.Form["__EVENTARGUMENT"] will give the object causing the post back and the event argument. If the data grid does not cause the postback, then there is likely a value somewhere in the post. Use Fiddler to look at the request being sent when the button is clicked.
