Hi,
is it possible to authenticate a kendo ui for asp.net mvc app? i mean the same way we use [Authorize] for plain asp.net mvc 4.

Thanks in advance and i look forward to your kind responses

Hi,
I am new to Kendo and started working with the trial version. I have a scenario where in a Grid User should have the ability to drag value from one cell in grid to another cell and also drag one cell value from one grid to another. I have tried searching but cudn't finad any such demo. I have used this demo http://jsfiddle.net/JBeQn/ 
I tried changing the source but it is not working. Currently when i drag and drop in the grid in demo value of two columns are dragged i just need that only one value , say only value of text column should be dragged. 
I surely think I can get lots of input on this here.
Thanks

hi, I'm working around KendoUI Wrappers for ASP.NET MVC 4 .

Now, I'm having some problems with my Cascading DropdownList when I reload Parent data.

for example:
1. I have a dropdown list like this: Level 1 > Level 2 (Level 2 cascades from Level 1).
If i reload data from Level 1.
=> Level 2 will reload data from server too.
but:  if (Level 2 Old Values == Level 2 New Values) => Level 2 doesn't reset to default value anymore.

2. The second issue that:  When i have a Dropdown List with more than 3 levels.
Ex : Level 1 > Level 2 > Level 3 > Level 4>Level n.

I reload data from Level 1 
=> It resets Level 2 , Level 3 to default Values .
=> but it can't reset Level 4 and level n...

So, how can i resolve these problems :-s ...
and This is my code:

The detail records that are found and returned by the function HierarchyBinding_RegulatoryReference are not being shown. I have verified that the StudyID is being correctly sent in and that the LINQ returns records but they are not shown. It shows that there are 0 detail records.

Here is the view:

    @(Html.Kendo().Grid<StudyViewModel>()
        .Name("StudyGrid")
        .Columns(columns =>
            {
                columns.Bound(item => item.StudyID);
                columns.Bound(item => item.StudyName);
                columns.Bound(item => item.StudyDirectorName);
                columns.ForeignKey(p => p.NatureOfStudy, (IEnumerable<LRRI.QAM.ViewModels.NatureOfStudyWithIDViewModel>)ViewData["NatureOfStudyList"], "NatureOfStudyID", "NatureOfStudy");
                columns.ForeignKey(p => p.Status, (IEnumerable<LRRI.QAM.ViewModels.StudyStatusWithIDViewModel>)ViewData["StudyStatusList"], "StudyStatusID", "StudyStatus");
                columns.ForeignKey(p => p.Active, (IEnumerable)ViewData["ActiveList"], "ActiveID", "Active"); 
            })
            .ClientDetailTemplateId("studyRegulatoryReferenceTemplate")
            .DataSource(ds => ds
                .Ajax()
                .Model(model =>
                {
                    model.Id(m => m.StudyID);
                })
                .Sort(sort =>
                {
                    // Sort by Name in descending order
                    sort.Add(m => m.StudyName).Ascending();
                })
                .Read(read => read.Action("StudyDataSource", "Study"))
            )
        .Pageable()
        .Sortable()
        .Filterable()
          )
    <script id="studyRegulatoryReferenceTemplate" type="text/kendo-tmpl">
        @(Html.Kendo().Grid<LRRI.QAM.Models.StudyRegulatoryReference>()
                .Name("RegRef_#=StudyID#")
                .Columns(columns =>
                {
                    columns.Bound(o => o.RegulatoryReferenceID);
                    columns.Bound(o => o.RegulatoryReference);
                })
                .DataSource(dataSource => dataSource
                    .Ajax()
                    .Read(read => read.Action("HierarchyBinding_RegulatoryReference", "Study", new { studyID = "#=StudyID#" }))
                )
                .Sortable()
                .ToClientTemplate()
        )  
    </script>

Here is the controller:

        public ActionResult StudyDataSource([DataSourceRequest] DataSourceRequest request)
        {

            var listValues = (from l in _context.Studies
                              orderby l.StudyName
                              select new QAM.ViewModels.StudyViewModel()
                              {
                                  StudyID = l.StudyID,
                                  StudyName = l.StudyName,
                                  ProtocolNumber = l.Protocol.ProtocolNumber,
                                  StudyDirectorFirst = l.StudyDirectorFirst,
                                  StudyDirectorLast= l.StudyDirectorLast,
                                  StudyDirectorName = l.StudyDirectorFirst + " " + l.StudyDirectorLast,
                                  NatureOfStudy = l.NatureOfStudy,
                                  RouteOfAdmin = l.RouteOfAdmin,
                                  Status = l.Status,
                                  StudyType = l.StudyType,
                                  GLP = (((Boolean?)l.GLP ?? false) ? 1 : 0),
                                  Active = (((Boolean?)l.Active ?? false) ? 1 : 0)
                              });
            return Json(listValues.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);
        }
        public ActionResult HierarchyBinding_RegulatoryReference(int studyID, [DataSourceRequest] DataSourceRequest request)
        {
            var listValues =
                _context.StudyRegulatoryReferences.Where(l => (l.StudyID == studyID))
                        .OrderBy(l => l.RegulatoryReference);
            return Json(listValues.ToDataSourceResult(request));
        }

I have this line of code
However I keep getting an invalid Template error. How can I format this to display only the time (12 or 24hr). Thanks

Hi here,

I'm building a web application with ASP.NET MVC4 and everything runs quite well so far. No I wanted to integrate Kendo UI to my _Layout.cshtml file in order to use some widgets. So I followed these steps (here) to include the neccessary scripts and styles, but when I run the project, it throws a JavaScript exception:

Unbehandelte Ausnahme in Zeile 17, Spalte 14133 in http://localhost:54430/Scripts/KendoUI/js/kendo.all.min.js
0x800a138f - Laufzeitfehler in JavaScript: Die Eigenschaft "msie" eines undefinierten oder Nullverweises kann nicht abgerufen werden.

When I comment out the reference to kendo.all.min.js everything works flawlessly. What can I do? I'm having a hard time telling my Boss that it actually was a good idea to spend more than thousand bucks on a bunch of tools that do not work. Please help me wih that!

Regards,
Rob

Here's my code:

(PS: I also tried adding a reference to kendo.aspnetmvc.min.js (one time before Kendo.all.min.js, another time behind it), but it didn't help.)

Error 5 'System.Web.Mvc.HtmlHelper<System.Collections.Generic.List<SOH.Common.Model.Patient>>' does not contain a definition for 'Kendo' and no extension method 'Kendo' accepting a first argument of type 'System.Web.Mvc.HtmlHelper<System.Collections.Generic.List<SOH.Common.Model.Patient>>' could be found (are you missing a using directive or an assembly reference?) c:\VSProjects\SOH.Orthodontics\SOH.Orthodontics.Web.UI\Views\Patient\PatientResult.cshtml 5 8 SOH.Orthodontics.Web.UI

Really struggling with this error.  Please help!  Html.Kendo() in the razor view just is not recognised!  Argh!!

Added a reference to the dll and also added namespace to BOTH web.config files.  Sections below from both files.

I have an ajax grid with several pages of data that I allow users to perform CRUD operations on using the InCell edit mode. However, if I change pages or ordering or manipulate the page in any way after making a change the default behavior is to discard changes. I've noticed that if I set .ServerOperations(false), I can navigate without losing my changes but I also lose the 'dirty mark' indicating that there have been changes. This is likely to cause users to navigate away from the page and lose those changes with no feedback from the page. While that can still happen with a dirty mark, the client has decided that they would prefer that any changes be saved prior to changing pages or filtering (basically, any of the _Read events).

What is the best way to enable a save operation prior to losing data in such a grid? 

Hi,

I have to say, I wasted now really a lot of time in figuring out how the css styles are applied to the grid edit controls:

I did two tests:
1) Use the Kendo Grid with Javascript configuration
2) Use the grid with MVC Wrapper configuration

And I get different styles for the editors (e.g string editors) when doing that! After research, probably that's what explained here: 
http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/editor-templates

In Version 1), the text boxes get the class "k.input k-textbox". Fine, that's what I want
In Version 2), the tet boxes get the class "text-box single-line". Why the difference?

Do I really have to declare editor templates now for every data type I want to edit? In that case, I could probably go on with the free Kendo edition and do not use the server wrappers. Why does it cause additional effort when I use them? Can someone explain?

Thanks!

Is it possible to have forced list matching similar to the ComboBox in the non-Kendo controls (http://demos.telerik.com/aspnet-mvc/razor/combobox/clientsidebinding) in the Kendo ComboBox? It seems there is no way to prevent the user from typing whatever they like into the input box.

This functionality also exists in the ASP.NET Ajax Combobox (http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/autocompleteclientside/defaultcs.aspx)
