Hi:

Yesterday I downloaded  Kendo UI for a trial.  I was able to install without any errors that I could see, but when I try to run the demo in VS2010 SP1 I  have the following issues:
 
1: Message at start: "Attaching the script debugger to process ... iexplore.exe on machine ... failed.  A debugger is already attached.  There are no other VS or Dev Server instances running.  This error is not crucial as I can proceed with the demos.

2. When I navigate to the Treeview with remote data demo, the only thing I see above the sources after delay is "Request Failed" with a retry button.

3.  It appears some of the sources are missing including these references from Index.cshtml:
<link href="@Url.Content("~/Content/shared/suite.css")" rel="stylesheet">v
<a href="@(Url.RouteUrl("RazorDefault", new { controller = "Suite", suite = "web" }))" class="imgPlate"><img src="@Url.Content("~/Content/shared/demos-web.png")" /></a>  (both the class and the png are missing.  In fact the Content folder is empty.)

4. In the grid binding to local data at line 3 in  c:\Program Files (x86)\Telerik\Kendo UI for ASP.NET MVC Q1 2013\wrappers\aspnetmvc\Examples\Areas\razor\Views\web\grid\local_data.cshtml, the code  @(Html.Kendo().Grid(Model)... gets a "The system cannot find the file specified" error.

Except for the first item, the errors are the same whether I start in VS or just click on the demo link in the  windows menus. 

The simpler examples mostly work, but what I need Kendo UI for is databinding against remote data, mostly with the grid and treeview, so I really need working examples of these,.  It appears that the demo that comes in the Kendo MVC MSI has not been properly QAed.  Or possibly there is some other cause on my machine.  Is there another source of these demos that I can try?  or can you help me resolve these issues?

Thanks,

Terry

Hi,

I have a dropdownlistfor that uses templates to display an image for each dropdown entry

I am having trouble retrieving the correct data.

   @(Html.Kendo().DropDownListFor(model => model.Image0Id)
                    .DataSource(source =>
                    {
                        source.Read(read =>
                        {
                            read.Action("GetImageIds", "Home");
                            read.Type(HttpVerbs.Post);
                        });
                    })
                    .Template("<img src='" + @Url.Action("GetImage", "Home", new { imageId = "#=data#"}) + "' width='128' height ='51'/>")
                    .OptionLabel("None")
                    .AutoBind(true)
                )

The #=data# is actually returning my ViewModel so when pass value to GetImage() I have a problem.
If I replace #=data# with say the number 2, the template works and fetches my image with id of 2.
If I insert some javascript #{alert(data)#} to alert me of the data values returned by GetImageIds() it returns the expected values.

I am using this in a similar scenario elsewhere where my template is as follows:
.Template("<img src='" + @Url.Content("~/Images/Banners/#=data#") + "' width='128' height ='51'/>")

This works perfectly.

Anybody have any ideas here?
 

Hi,

I have two kendo grids which needs to be placed side by side (Both the grids uses same controller method).

My requirements.

1. Have to load >50000 rows(shouldn't take much time to load).
2. Scrolling should be in sync.
3. Paging should not be applied.
4. Column width should be auto.
5. Row height should be same for both the grids so that scrolling make sense.

Please share a demo on this.

I'm creating a Kendo.Mvc.UI.Menu in a Html Helper.  If the current controller/action matches the menu item then i set Selected to true. However, when the menu gets rendered to the page the current menu item is not selected.  Is there an init or onload event that is ignoring or overriding the Selected property?  It seems to only effect the current controller/action, if i set other menu items to Selected = true, they will stay selected.


Sorry, still transitioning from Telerik.Mvc...

Thanks,
Chris

I can't seem to get remote validation to work in my popup edit window.  Normal validation ([Required] etc) seems to work fine, but the remote call to the JsonResult method isn't working.  In a plain MVC view for the same model the remote validator works as expected.

Here is the grid (most irrelevant columns removed)

Here is the controller JsonResult:


Here is the model (irrelevant fields removed):


This identical model works fine in a standard scaffold generated view.  Any ideas?

Hi,
I have put in a general error handling to handle exceptions and authorisation errors for all Ajax calls, both Kendo and my api. I send back status 500 of exception and 401, Forbidden, or 403, Unauthorized, for authorisation errors.

The problem is I do not seem to be able to prevent the dataSource from updating the display if I get a non-200, OK, response. Looking at the code in Chrome it does not call the function associated with 'databinding' on line 13 of the code below. Can you suggest what I have done wrong?

Thanks in advance.

I am migrating an application from release 2012.3.1114 to release 2013.1.319.  Previously, I was able to apply HtmlAttributes on columns in this manner: With release 2013.1.319, an "invalid template" error is generated from the above code.  If I change HtmlAttributes to HeaderHtmlAttributes, no errors are generated and the style is applied to the column header (i.e. the format of the HtmlAttributes isn't a problem).  I did verify that I could use HtmlAttibutes on a column with an @class parameter successfully, which is the correct way of applying styles.  I guess I'm wondering if this capability (local CSS styling via HtmlAttributes) was intentionally removed, or if I'm doing something wrong?

Note: Moved from Kendo UI Web forum.

I have read several tutorials and have a few basic questions regarding mobile development and Kendo.
1.  I am building mobile apps with MVC 4 and VS 2012.  Do I only need to use Kendo Mobile UI or do I also use Kendo UI Complete for ASP.Net MVC?  What is the difference?
2.  I also want to use OpenAccess ORM, but do not understand where this integrates with Kendo UI Mobile (is there any good samples)?
3. This will be hosted via Azure websites, is there any gotchas before I moved forward?

Thanks for the help, I must admit it is not very clear which toolset to use at this point.

I have a combobox with over 100000 records, but it's unusable, it makes the browser very slow and unresponsive.

I'm using it like this:
I've also tried setting Autobind(false), but when I try to open the combobox it becomes unusable.

I've tried limiting the number of records returned, but once it's databoud, it seems it won't call the server method again no matter what I type in the box.

Any help on how to make the combobox usable with huge number of records?

Hi,
I implemented Kendo Grid helper in a MVC 4 with WebApi application, but I don't know how can I set de column list to change dinamically the rows that it shows.
My code:
@(Html.Kendo().Grid<Bitacora.WebUI.Models.WhiteBoard.XXXGridModel>()
            .Name("Grid")
            .AutoBind(true)
            .EnableCustomBinding(true)
            //.BindTo(Model.xxxx.YYYList)
            .Columns(c =>
            {
                c.AutoGenerate(column =>
                {
                    //customize autogenereted column's settings                                                    
                    column.Width = "150px";
                    
                    //column.ClientTemplate = "<input type='checkbox' name='checkbox' />";

                });
            })
            .Scrollable(scrolling => scrolling.Enabled(true).Height("auto"))
            .Resizable(x => x.Columns(true))
            .Events(events => events.Change("searchCalls"))

                                                   .ServerOperation(true)) // Paging, sorting, filtering and grouping will be done server-side  
                                                //.ColumnMenu()

                                                                                            operators.ForNumber(strFilter => strFilter.Clear());
