};

.Cs File

        {           
            return "Hello"+ PHYID;
        }

pls help me as soon as possible....

It would probably go a little something like this. You would have to rewrite some stuff because you cannot directly return the result of an ajax request in a JS function. This is because it's an asynchronous call, so you'll need a callbck.

Code:

---

tooltip_text = function(start, end, event) {   
      EHR.GetPhysicianName("Test", {
            success: function(result) {
                // do whatever you want here, the string returned from the server is inside the var 'result'.
            ;}
      });
};
 
.Cs File
 
[DirectMethod]
        public static string GetPhysicianName(string PHYID)
        {           
            return "Hello"+ PHYID;
        }

But here i want return type.how to return the result.
EX:

SetPhysician=function("Test")
{
EHR.GetPhysicianName("Test", {
success: function(result) {
// do whatever you want here, the string returned from the server is inside the var 'result'.
;}
});
return result;
}

here SetPhysician Function is returning the result(i.e is Server side function return string).pls help me

Try this one

.cs

Code:

---

[DirectMethod]
public static string GetPhysicianName(string PHYID)
  {         
        return "Hello"+ PHYID;
  }

---

Js

Code:

---

function getPName(data){

 EHR.GetPhysicianName(data,onSucc);

}

function onSucc(args){

    //to check the value
    alert(args);

}

---

Its not working.
.CS
[DirectMethod]
public static string GetPhysicianName(string PHYID)
{
return "Hello"+ PHYID;
}
.JS
scheduler.templates.tooltip_text = function(start, end, event) {
var PhysisianName="";
PhysisianName= DirectMethod.GetPhysicianName("Name");
return "<b>Patient:</b> " + event.text + "<br/><b>Physician Name:</b> " + PhysisianName ;
};


The above code i am using to call the serverside return type function, it returns var variable(physicianName), That return value is concatinating to mainfunction( scheduler.templates.tooltip_text in .js).

But the above code is retuning the undefined value?????
Please do some help , is any idea!!!!!

you cant call the directmethod directly, you need a callback..

how to create the callback give me related example..
