Hi:

I have a Learning Management System that makes extensive use of Telerik Rad Ajax controls and in which I have invested a lot of time in developing the data component including the stored procedures.

I would like to be able to host and play lessons on mobile devices.  I've been looking at MVC and have managed to get myself quite confused.  It seems to me that if I make the transition to MVC - and then use the Kendo extensions on top of that, I loose much of my development in the data layer in my system.  However, I'm not sure that I understand MVC sufficiently to know if that's correct.

What do you suggest would be the most effective path for me to be able to concurrently deploy my LMS on both traditional Web and mobile devices - moving from a totally traditional .Net Web application.  What is the quickest way to make this transition?  What will be most cost-effective for long term support and maintenance of my system?

Any suggestions greatly appreciated.

I can't seem to work out how to populate the listview with jsonp data from PHP. I know there's a very good sample in the demos, but as I can't see the serverside, it's hard for me to know where it all goes wrong. 

If anyone could have a look at my source and give me some hints in the right direction I'd be forever grateful!

I have some problem with remote validation.

There is part of model

[DisplayName("For User ID")]
[Remote("CheckUserID", "User", ErrorMessage="Must be from list or Empty")]
public Nullable<System.Guid> ForUserID { get; set; }

View

@(Html.Kendo().ComboBoxFor(model => model.ForUserID)
            .HtmlAttributes(new { style = "width: 200px;" })
           //.Name("ForUserID")
           .Filter("contains")
           .Suggest(true)
           .Text("Select user")
           .Placeholder("Select name if necessary")
           .DataTextField("UserName")
           .DataValueField("UserId")
           .AutoBind(true)
           .DataSource(source =>
                           {
                               source.Read(read =>
                                               {
                                                   read.Action("GetUserWithId", "User"); //Set the Action and Controller name
                                               })
                                   .ServerFiltering(false); //If true the DataSource will not filter the data on the client.
                           })
             
           //.Events(e => { e.Select("userNameChange"); })
                   .Events(e => { e.Change("userNameChange"); })
          )

And action in Controller  UserController

[HttpGet]
public ActionResult CheckUserID(String userIdString)
{
    if (Request.IsAjaxRequest())
    {
           bool result = true; 
        JsonResult res = Json(result, JsonRequestBehavior.AllowGet);
        return res;
    }
    return RedirectToAction("Index", "AccountBoost");
}

All javaScripts for validation included into page, client validation works with Text Input that is also on this page. 

 I can get into action when typing in browser /User/CheckUserID .

But I never get into  CheckUserID action if I work with ComboBox.

Hello,

I have a grid using remote data vistualization connected to an OData datasource.  Everything is working correctly but if I add a filter, then call a datasource.read() and a grid.refresh(), the first records will be loaded but for some reason, the.count returned by the OData service seems to be ignored.

So if you have set the grid pageSize to 50, only the first 50 records will be requested to the server and then, no more call will be sent to the serveur (even if a count of 300 was returned by the jsonp response).

Can you confirm if this is a bug?

Best regards,

Simon

Hi,

I'm using Kendo Editor and I just noticed a strange behavior but only in Chrome.  It woks fine in IE and FF.

When I have the editor displayed on the page many buttons or links on the page just change their behavior to make the content scroll and also when I mouse over the button bar of the editor.

I found a work around by hovering the mouse over the text part of the editor from the side of the editor and then going up to hover over the button bar.

Does anybody knows of this and is there any way to circumvent?

Thanks

I am using comboboxes in a Kendo grid, and have not had any problem with the model binding working when the data is posted back to the server by the grid.  However, I just tried using a Kendo ComboBox in a traditional form that does a standard post (instead of an ajax post), and model binding does not work.  The reason is that the posted values don't match the MVC conventions for child properties.  

A quick example:

Let's say you have a combobox bound to an Employee property in your view model, and the Employee object has two child properties - EmployeeName and EmployeeId.

If you look at the ajax post of the data when this ComboBox is used in the grid it looks like this:

Employee.EmployeeId
Employee.EmpoyeeName

But when you put the the same ComboBox in a standard form, and post back to the server, the values are posted like this:

Employee
Employee_input 

This causes the form data not to be bound to the model accepted by the controller action method, since this naming standard does not follow the MVC binding conventions.  Why does this control behave differently in these two scenarios, and how can I make it start working in my forms?  Is there a Kendo model binder I need to register in my project?  This is a rather urgent issue, as we are getting ready to launch a Kendo Grid implementation, and this is breaking the existing forms now that they have been converted to use Kendo Comboboxes.  

I already created a support ticket for this, but thought I would try the forums as well, as I need to find a solution ASAP.

Thanks, DanO

My applicartion has a ListView which has a detail view similar to "Sushi" app.
 
I need to add an array of images instead of singe image in my detail view which is implemented as template similar to sushi app again.

Can you provide me a pointer how this can be implemented,
Btw, I tried to find a span(place holder) and replace html using jquery, but it did not work.

Thanks

Hi,

Can I get the current state of the Kendo UI GRID?

What i'm trying to do is allow my end users to change a grid according to their specifications(filtering, sorting, column reorder) using functionalities that come out of the box with Kendo UI. However, what I want to know is after the user does their specifications, is there any way for me to get a snapshot, a json/xml string or anything else that I can save and later load back onto the grid?

Hi all,

I couldn't find a solution into the forum.

How can I prevent from writing into the control box?

I'd like to allow the user to - only - set the date from the calendar panel.

Thanks a lot.
