You want to fire or catch event?
By the way it is onblur, if it helps.

Google[^] to know how to catch it on serverside.

My 5. I would recommend doing it on the client side only as the latency would kill performance -- this event is way too frequent to post back and wait for response.

OnBlur is right thing to handle. OP wants to handle on server side but -- see my comment to the answer by Prerak. My 5 for this one.

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......................
}

regards ,
