I think it would be more helpful if the Kendo UI Documentation is structured similarly to other Telerik Product Documentations where each control (widget) provides a complete overview, visual structure, getting started, and a how-to section (which I'm guessing is a compiled list of frequently asked scenarios).  I'm struggling/spending too much time having to research how to do (what should be) the simplest things with these widgets.  It seems that' I'm having to revert to the Demo's and online threads more than the documentation.. that' can't be good!

The Multiselect control hardcodes the style of the Placeholder to Arial, 13px. Please make this either have HtmlAttributes or put a style on it, that can be overwritten.

It´s the only missing pice of this great framework. I really hope for it in a near feature.

I am using Kendo Scheduler to show the appointments. I have appointment creation/edition screen. I want to redirect it to that page whenever user tries to add/modify an appointment/ Recurring  appointment  from Scheduler. I want to hide the Edit Recurring Item popup message in KendoUI Scheduler while editing recurring appointment as I want to edit the whole series instead of editing single occurrence. So whenever user tries to edit recurring appointment, i want to redirect it to appointment editing screen with all the details without showing any message.

There is No Model Binding feature available for DataTable.ToDataSourceResult() Function, Implementation of this feature makes Kendo UI much interesting.

Create a breadcrumb trail like horizontal navigation on top of web page below headers which will provide a hierarchical site structure.

Typical breadcrumbs looks like:
Home page > Section page > Subsection page

Hi
It is possible to create a form layout with navigation toolbar to navigate between records?

In windows application you can use textbox and other controls and bind this controls to datasource and use navigation toolbar to navigate between records.
Also this form layout can design for master-detail layouts with grid widget or other widgets.

Presently, there's no way to pass a parameter to the Deferred function. If i have a need to make the control deferred depending on a condition, i have to write the code this way:

@{
    var treeView = Html.Kendo().TreeView()
        .Name("aName");
        
    if (this.IsAjax)
    {
        treeView.Deferred();
    }
    
    treeView.Render();
}

It would be great if we could pass a parameter that way:

@(
    Html.Kendo().TreeView()
        .Name("aName")
        .Deferred(this.IsAjax)
)

In the ASP.NET MVC Wrappers for kendoWindow there is a Visible(bool) option which the docs suggest is to stop the window displaying on page load.  

However, setting it to true or false and the generated javascript is always the same and the window opens on page load.

I'm now creating them manually in javascript myself to get round that but would be nice to use the MVC wrappers as they are intended.

Please suggest me any control available of kendo UI to display multi level relational database with add,edit and delete exclude Treeview

We all know that the default JavascriptSerializer built into ASP.NET leaves much to be desired, which is why developers are swapping out the built in one from ASP.NET for others such as JSON.NET and ServiceStack.

The issue that a lot of developers encounter when working with the MVC Wrappers is that it appears to be using the build in JavascriptSerializer, which is miserably slow and hard to work with when trying to take data from an ORM (with navigation properties) and display it on the Grid. Most of our grids closely represent a table in our database, but because the JavascriptSerializer doesn't support any type of navigation properties, we are always forced to write some DTO that flattens the object out to contain just simple datatype properties.

If we could REPLACE the JavascriptSerializer with our own framework - such as JSON.NET or ServiceStack, then we would be able to get our job done a lot faster without the extra plumbing.

This feature would mean that this "known issue" could be resolved by people simply swapping the JavascriptSerializer for a better one:

To have a consistent look in grids toolbar, it should be possible to add an icon class to custom buttons. Not possible through .HtmlAttributes() because those gets applied to the wrapper link and kendo icons are displayed via inner span tag.

.ToolBar(toolbar =>
    {
        toolbar.Create(); // Has [+]-Icon
        toolbar.Custom().Text("My Custom Button"); // Does not have an icon
    }

Would be nice to have an option like

toolbar.Custom().Text("Reset Grid Settings").Icon("k-i-funnel-clear");

which results in 

<a href="/Tarife" class="k-button k-button-icontext">
    <span class="k-icon k-i-funnel-clear"></span>
    Reset Grid Settings
</a>

OData support for Kendo UI ASP.NET MVC Server Wrappers

I want to load a particular ViewModel into a treeview but using the MVC wrappers does not allow for setting what field will be the Id, and the hasChildren property. The model information can be set via the JavaScript configuration though.

It would also be nice to mark additional data on the model that should be sent to the Read action along with the Id from my item.

Kendo UI Menu currently supports only mouse over on child/sub menu items.

Root items are configurable to open only if moust is clicked.

But actually child items also should have the same type of configuration.

In my organisation people simply clicking everytime on menu items, they dont wait for the mouse to open its child items. And when the child menu items opened they press mouse button by mistake and the menu gets closed that gets them irritating.

I need configure in my Razor View, with my Multiselect helper, the maxselectedItems property (like others properties: MinLength, Filter,etc)

Currently for the Window and Tooltip controls (possibly others, but those are the ones that I'm working with), the Height and Width properties are both integer properties which set the height and width in pixels.  I would like the ability to be able to enter Height and Width in 'em' units, much like can be done with the grid column widths. 

Most of the time DefaultValue isn't known.  Allow us to enter null or don't require it.

Include an x.js as well as x.min.js files in the upgrades. MVC's bundle config by default does not include the .min file in debug mode.
