MVC parameter from JQuery null

MVC parameter from JQuery null

I am trying to implement sorting on a custom grid I am working on and
having an issue with jQuery to MVC parameter binding.
I have a Jquery request like the one shown below
// Javascript
var dataobj =
{
test: 3,
sortInfo: self.sortInfo,
pagingInfo: {
TotalItems: 34,
//headercontainer.attr("data-pagingInfo-TotalItems"),
ItemsPerPage:
headercontainer.attr("data-pagingInfo-ItemsPerPage"),
CurrentPage:
headercontainer.attr("data-pagingInfo-CurrentPage")
}
};
$.ajax({
url: self.viewModel.GenericGridHeaderModel.SortingCallbackUrl,
type: 'POST',
data: dataobj,
dataType: "json",
success: function (html) {...}
});
// C#
public PartialViewResult GenericGridSort(int test, SortInfo sortInfo,
PagingInfo pagingInfo){
...
}
At the moment I have non null values in sortInfo object in Javascript and
I see that the values are posted correctly however inside the action
method the values are not getting bound correctly. All I see is default
values for the sortInfo and pagingInfo parameters. In fact the test
parameter is getting the value 3 correctly.
For clarity here is my sortInfo model
public enum SortDirection
{
None = 0,
Ascending = 1,
Descending = 2
}
public class SortInfo
{
public int FieldIndex { get; set; }
public string FeildName { get; set; }
public SortDirection SortDirection { get; set; }
}
Can anyone tell me what am I missing here ?
Thanks all !
