您要触发或捕获事件?
顺便说一句，如果有帮助，它是onblur.

我们可以使用javascript进行相同操作，请尝试使用javascript.

我们可以使用__doPostBack函数将控制权从客户端更改为服务器端.

我们可以使用dopostback函数将参数传递给服务器端.
它在服务器端导致回发，在服务器端接受该参数，并根据条件进行绑定

在javascipt函数中
__doPostBack(''onfocusout'');


在页面加载中

字符串strText = System.Web.HttpContext.Current.Request.Params.Get("__ EVENTTARGET");
如果(strText.Equals("onfocusout"))
{
在这里做你的代码..........绑定..........
}

Hi,
We can do the same by using javascript,please try it using javascript.

we can change control from the client side to server side using __doPostBack function.

we can pass argument to the server side using dopostback function.
it causes postback in the server side ,accept that argument in server side and and do ur binding according with condition

in javascipt function
__doPostBack(''onfocusout'');


in pageload

string strText = System.Web.HttpContext.Current.Request.Params.Get("__EVENTTARGET");
if (strText.Equals("onfocusout"))
{
do your code here..........binding......................
}
