I need to make a cascading combobox with server filtering but I'm having trouble setting the initial value.The dropdownlist on which the combobox depends looks like this:

Where:

• model.SelectedCompany is a string
• Name attribute is set because I need that in the combobox (I've read on the Kendo UI forums I'm not supposed to specify it, but I don't know how to do the cascading combobox without it)
• Model.CompanyList is a List<string>

Hello,

I am using a Kendo Grid popup which displays a Kendo editor to modify the content of the field. The field is configured on the MVC server side with the annotation to validate length to be 500 characters as follows:

[AllowHtml]
[StringLength(500, ErrorMessageResourceName = "ActionMaxLength", ErrorMessageResourceType = typeof(Resources.Messages))]
public string Action { get; set; }

If the user enters more than 500 characters in the Kendo editor this validation works. However, our users reported that when they added more formatting (tables, bullet lists) the validation pops up even if the visible character count is not 500. I understand from a technical perspective the character count being validated includes the behind-the-scenes html formatting tags, however this is not intuitive to the end user.

My question is, is there any alternative or built in approach to validate just the html-stripped character count of the Kendo editor validation?

Regards,

I am currently trying to add custom markers to a map in MVC C#.
Is there anyway of creating a different shape/image in MapMarkersShape to display it on the map?
My current code is as follows:

@(Html.Kendo().Map()
    .Name("map")
    .Center(30.268107, -97.744821)
    .Zoom(3)
    .Layers(layers =>
    {
        layers.Add()
            .Type(MapLayerType.Bing)
            .Shape(MapMarkersShape.Pin) // -< this line
            .Key("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"); 
    })
)

Thanks

I have a View with multiple dropdowns(15-20). Currently I implemented server binding for all of these by creating ViewData for every dropdown before loading the View. Is this the best way for implementing multiple dropdowns(server binding)?
Note: Don't want to use AJAX binding.

Hi,
 
I have used Kendo UI in an MVC web application. Of late I have been experiencing slowness in IE8 browser.
While the same code loads the screen in less than 2 secs in Chrome/IE10, it takes more than 5-6 seconds to load in IE8 browser.
Kendo widgets used in the screen includes Dropdowns, Treeview and Kendo Tabstrip.
I have tried replacing the kendo dropdowns with normal ones. This gave me a slight improvement of about 1 sec.
The kendo dropdown is a part of my cshtml page and not initialized by the jquery. Is this the best way to implement kendo widgets?
Is there any other way which will provide me with a better performance?

So I am using the latest build at the time of writing this "2014.2.909" and I have some "info" tooltips that the contents will dynamically change based on a combobox selection.

The tooltip is set up like this: 


Now I am using a template like this:

 

(You can hopefully see I am using bootstrap theme here as well) 

The current tooltipReset function I have created functions like this: 



On top of this I have had to override the current styling to make sure my bootstrap panel appears as I want it without the black surround: 



Now this shows a mini panel that floats as I require but I can't seem to get the size to dynamically expand/ contract based on the content being supplied. I tried setting the width to "auto" but this didn't seem to expand the right hand side so the text was either touching or overlapping the panel contents. 

So is there a better way of doing what I want? 


On top of that is there a better way to restyle the tool tips as the changes I have put in have affected other tool tips I have. These are not related to this like graph tool tips etc. 

Thanks in advance.

I'm using VS2012 and MVC5. I dowloaded the telerik.ui.for.aspnetmvc.2014.2.903.trial and followed the below steps

Added the Kendo.Mvc.dll reference to my project. (got Kendo.Mvc.dll from telerik.ui.for.aspnetmvc.2014.2.903.trial\wrappers\aspnetmvc\Binaries\Mvc5)
Copied the JS and Style folders from telerik.ui.for.aspnetmvc.2014.2.903.trial
Created BundleConfig.cs as per the telerik website tutorial
added the reference link _Layout.cshtml and did the web.config settings as suggested

when i run the application i'm getting javascript runtime error in the following debugger code

jQuery(function(){jQuery("#datepicker").kendoDatePicker({"format":"M/d/yyyy","min":new Date(1900,0,1,0,0,0,0),"max":new Date(2099,11,31,0,0,0,0)});});

can please help to resolve my issue.

I am re-wiring a grid from traditional MVC to use a Telerik Grid and have a grid that appears not to be requesting data from the controller:


Controller:

GIven this is non-Ajax I'd expect the Grid to 'read' the datasource upon initial rendering, but a breakpoint in the first line of 'UserRolesRead' is never hit and the Grid is rendered empty.

Anyone any ideas?
Thanks
