Webmethod is not called in asp.net C#

var obj = new FormData();

var files = '';

 

files = $("#imgUploadPromition").get(0).files;

 

 

// Add the uploaded image content to the form data collection

if (files.length > 0) { 

obj.append(fName, fileData); 

}

else {

alert('Please Select File');

return;

}

$.ajax({

type: "POST",

url: "Content_New.aspx/UploadFiles",

data: obj,

processData: false,

contentType: false,

//dataType: "json",

success: function (result) { alert("successful!"); },

//async: true

})

I see that the UploadFIles method does not accept any argument but you are passing it in the ajax request. I think something is wrong there. Maybe you should modify the UploadFIles signature to accept a HttpPostedFileBase object. Also, I think you don't have to specify json type for the request.
