I need to pass a json data to the controller. hence i have created a ajax post. But it is not calling the action method.

$.ajax({
    url: '@Url.Action("DeleteGridRow","Project")',
    type: 'POST',
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    async: false,
    data: JSON.stringify(postData),
    success: function (data) {

});

}

My Actionmethod

 [HttpPost]
    public JsonResult DeleteGridRow(string postData)
    {
        return Json(null);
    }

Please help

If you have separated your javascript file from your cshtml or vbhtml page, then this is not going to work. Your URL would be interpreted wrongly. You should pass URL where you are submitting to your function DeleteRow. Something like this:

$("#myForm").submit(function() {
    var url = $(this).attr("action");
    var data = Use your method to collect data or $(this).serialize();

    DeleteRow(url, data);
});

function DeleteRow(url, postData) {  
    $.ajax({  
        url: url,  
        type: 'POST',  
        dataType: "json",  
        contentType: "application/json; charset=utf-8",  
        async: false,  
        data: JSON.stringify(postData),  
        success: function (data) {  

    }  
});

Something like this should work.
