I am working on asp.net MVC 5 Referring to my question i want to take difference between each two points like this 2-1 3-2 4-3 5-4 and so on and then put them into my series data in chart Bellow is my controller code //Getting data from DB to view in charts SqlCommand Device_Id_command = new SqlCommand("Select Device_ID, Energy_kWh,Power_kW,Voltage_Phase_1,Data_Datetime,Voltage_Phase_2,Voltage_Phase_3,Current_Phase_1,Current_Phase_2,Current_Phase_3 from [ADS_Device_Data] where Device_Serial_Number=@serial_number AND Data_Datetime between'" + time.ToString(format) + "'AND'" + time2.ToString

So I have one document table and a ApplicationUser table. One user can upload multiple documents and a foreign key constraint has been applied accordingly using the code first approach. But the problem is, I am able to save the document without assigning the UserID foreign key id in the Documents table . What am I missing here? Below is my novice attempt. ApplicationUser Model: it's the standard model provided by the framework. Document Model: public class Document { public int Id { get; set; } [StringLength(255)] public string FileName { get; set; } [StringLength(100)] public string

I'm tring to fill a javascript array with lat longs that I can use to put markers on a map from my model but it's riddled with errors and I'm not sure why. <div id="map"></div> <script> var map, points = []; @foreach (var a in Model) { //Error: The name 'points' does not exist in the current context //Error: ) expected ; expected (at front and end brackets) points.push({ lat: @a.Lat, lng: @a.Lon }); } function initMap() { map = new google.maps.Map(document.getElementById('map'), { center: { lat: -34.397, lng: 150.644 }, zoom: 8 }); //Error: The name 'points' does not exist in the current

I want to exclude the time part in the DateTime Textbox, but I can't make it work the way I want. This is how I set up the field : @Html.TextBoxFor(m => m.DateFrom, "{0:dd/MM/yyyy}", new { @class = "datefrom" }) @Html.TextBoxFor(m => m.DateTo, "{0:dd/MM/yyyy}", new { @class = "dateto" }) Jquery script: $(function () { $(".datefrom").datepicker({ defaultDate: "+1w", changeMonth: true, numberOfMonths: 1, dateFormat: "dd/mm/yy", onClose: function (selectedDate) { $("#to").datepicker("option", "minDate", selectedDate); } }); $(".dateto").datepicker({ defaultDate: "+1w", changeMonth: true,

ASP.NET MVC5 I have a combobox in a grid (InLine Edit): columns.Bound(x=>x.AccountID).EditorTemplateName("MyTemplate") Where MyTemplate is in /Shared There are millions of Accounts. When I try to edit the combo box in a grid and choose a new value, the ID of the Account, not the name, appears. This is because of course the name of the account is not immediately present so in the Read().Data() of the ComboBox.Datasource I need to send additional data ; the AccountID.

I am replacing the (HttpContext.Current.User) IPrincipal with a custom version so I can store more information login and the user. I have done this before using the FormsAuthtenticationTicket, but those other ways were based on the Memberhipship and SimpleMembership providers.

The length of the string exceeds the value set on the maxJsonLength property. Parameter name: input To remedy this, I have tried a number of Web.Config solutions.
