Hey, I found answer. It is as follows:

function checkBoxselectedornot() {         var frm=document.forms['aspnetForm'];        var flag=false;        for(var i=0;i<document.forms[0].length;i++)        {            if(document.forms[0].elements[i].id.indexOf('chkDownloadSelectedEvent')!=-1)            {                  if(document.forms[0].elements[i].checked)                  {                       flag=true                  }              }        }        if (flag==true)       {         return true       }else       {         alert('Please select at least one Event.')         return false       }  }
