This is my c# method
public async Task<ItemResponse<ActivityModel>> InsertActivityWithNote(ActivityModel model, string note)
I have send data in model but (note without model so how to send note field by ajax call)
note = $(".newnote-textarea").val().trim(); var data = new FormData(); data.CreatedOn = strDate; data.CreatedBy = userids; data.UserID = userids; data.ModifiedOn = strDate; data.ModifiedBy = userids; data.isActive = true; data.ActivityID = 3; data.PublisherID = 5000; data.OrganizationContactID = publisherData.organization.organizationId; $.ajax({ type: "POST", url: apiurl, dataType: "json", contentType: "application/json", data: JSON.stringify(data, note = note),
