the invocation bindpersonaluserslogdatatable method in c# file. within bindpersonaluserslogdatatable, code determine if logged in user admin or plain user.

if logged in user plain user, want dynamically make of columns in jquery datatable invisible.

could please tell me changes need make in order aforementioned code desired functionality?

you can use column().visible() or columns().visible() api methods dynamically show/hide single column or set of columns.

"success": function (msg) {    var api = $('#personaluserslogtable').datatable();     var json = jquery.parsejson(msg.d);     // enable/disable columns based on user type                if(json.isadminuser){       api.columns([2,3]).visible(true);    } else {       api.columns([2,3]).visible(false);    }     fncallback(json); },
