You can use the following page mathod for this

suppose you have link button with id "lnktest"

C#

string ctrlname = Page.Request.Params["__EVENTTARGET"];
           if (ctrlname.Contains("lnktest"))

Hi , Check on the ctrlname if it's null because it well be null
string ctrlname = Page.Request.Params["__EVENTTARGET"];
if (ctrlname != null)
{
if (ctrlname.Contains("LinkButton1"))
{
////////////////place your activities
}
else
{
////////////////place your activities
}
}
