Question

im having a problem passing a data to the controller in MVC3

I have a View that looks like this

@Ajax.ActionLink("MyController", "Myfunction", new {id =item.data},  
     new AjaxOptions
                    {
                      UpdateTargetId = "myDiv",
                      InsertionMode = InsertionMode.Replace,
                     })

<div id="myDiv"> </div>

And a controller that looks like this

       public ActionResult Myfunction(string data)
       {
              //some code
              return PartialView(chart);
       }

It all kinda works but the data dont get into the controller (its null when i set a breakpoint), when i hover over the link i see the data in the adressfield. do i have to make some adjustment in the routingtable?

Any input is appreciated.

Change this line:

@Ajax.ActionLink("MyController", "Myfunction", new {id=item.data},

to be:

@Ajax.ActionLink("MyController", "Myfunction", new {data =item.data},

The variable names declared in the POST need to match that captured by the server, in other words your Controller Action method is expecting a parameter data and its getting passed id
