It would be nice if Kendo offered an online tool that could produce a custom, minified JavaScript download with only the JavaScript code for specifically selected features.

In addition to Line and Bar chart types, it would be nice to have support for the Pie chart type.

I would like to request, for the following controls: Rich Editor, Data Filter, Masked Input for building business apps.

[Edited to remove tools already included in beta.]

In Chrome, you can type into the Editor's fontName tool to select a font. In IE, however, you can't type in a font, but rather can only select one using the dropdown. It would be good to be able to give the user a consistent experience across browsers. Ideally that would mean allowing them to type in a font in IE, but if that is not possible it would be good to be able to configure/turn off the ability to type in the control in Chrome and other browsers.

Inserting a new table in the editor in IE ignores the current cursor position and adds the table as the first element. If you add a new table, this will be added in the first cell of the first table.

The .value() function on the Editor control strips out some elements from the Editor HTML. For instance, tables created in the Editor have a BR tag inside the table cells, but those BR tags are removed from the string returned by .value().

In order to display HTML exactly the same as it appears in the Editor, it would be useful to have an additional function, perhaps call it .rawValue(), that does not strip out these elements. For instance, with the BR example, if a row does not have any content the row will collapse without the BRs, so it would be nice to have an additional function that leaves them in.

Mobile Date & Time Pickers would allow much easier use for inputting dates and times into a mobile ui.  The web date & time pickers use a drop down that is not the best solution for mobile use.

This is quite important especially in finance where we would want to overlay graphs with other graphs data for analysis.

Also would be good to enhance the controls to have more functionality such as min\max lines etc.

I need to create this ...

        ''' <summary>
        ''' Gets all categories
        ''' </summary>
        ''' <param name="categoryName">Category name</param>
        ''' <param name="pageIndex">Page index</param>
        ''' <param name="pageSize">Page size</param>
        ''' <param name="showHidden">A value indicating whether to show hidden records</param>
        ''' <returns>Categories</returns>
        Public Overridable Function GetCategories(Optional categoryName As String = "", Optional pageIndex As Integer = 0, Optional pageSize As Integer = Integer.MaxValue, Optional showHidden As Boolean = False) As IPagedList(Of Category) Implements ICategoryService.GetCategories
            Dim query = _categoryRepository.SelectOne
            If Not showHidden Then
                query = query.Where(Function(c) c.Published)
            End If
            If Not [String].IsNullOrWhiteSpace(categoryName) Then
                query = query.Where(Function(c) c.Name.Contains(categoryName))
            End If
            query = query.Where(Function(c) Not c.Deleted)
            query = query.OrderBy(Function(c) c.ParentCategoryId).ThenBy(Function(c) c.DisplayOrder)

            If Not showHidden Then
                'ACL (access control list)
                Dim allowedRolesIds = Ctx.CurrentUser.Roles.Where(Function(cr) cr.Active).[Select](Function(cr) cr.EntityId).ToList()
				query = From c In query Join acl In _aclRepository.SelectOne On _
				    New With { _
					 .c1 = c.EntityId, _
					 .c2 = "Category" _
				 Equals acl Select Var = acl
				} = New With { _
					 .c1 = acl.EntityId, _
					 .c2 = acl.EntityName _
				} Into c_acl From acl In c_acl.DefaultIfEmpty() Where Not c.SubjectToAcl OrElse allowedRolesIds.Contains(acl.RoleId) Select c

                'Store mapping
                Dim currentStoreId = _storeContext.CurrentStore.EntityId
				query = From c In query Join sm In _storeMappingRepository.SelectOne On _
				    New With { _
					 .c1 = c.EntityId, _
					 .c2 = "Category" _

					 .c1 = sm.EntityId, _
					 .c2 = sm.EntityName _
				} Into c_sm From sm In c_sm.DefaultIfEmpty() Where Not c.LimitedToStores OrElse currentStoreId = sm.StoreId Select c

                'only distinct categories (group by ID)
				query = From cGroup In From c In query Group c By c.EntityId  Into cGroup.Key cGroup.FirstOrDefault()
                query = query.OrderBy(Function(c) c.ParentCategoryId).ThenBy(Function(c) c.DisplayOrder)
            End If

            Dim unsortedCategories = query.ToList()

            'sort categories
            Dim sortedCategories = unsortedCategories.SortCategoriesForTree()

How do I get in VB.net

Your Kendo UI demos are useful, however they lack a basic overview to orientate new comers as to the specifics.  More importantly I would find it useful, and it would be more thorough, to provide examples in both Razor and JavaScript Syntaxes.

The Kendo UI Forums have limited usefulness, do not seem to be consistently monitored for new questions, there isn't a useful tagging or categorization structure.  The search engine does a poor job of identifying similar questions / answers.  There is no easy way to link Questions together and/or mark duplicates.  The Forum site goes down from time to time, given the extremely limited documentation, this leaves developers without reliable information readily available.

All of these shortcomings (which are more than adequately addressed by Stack Overflow) result in a fractured support and documentation infrastructure for Kendo UI.  

Migrating all unpaid support away from the forums to Stackoverflow will dramatically improve the experience.

If I only have 3 items in a grid then it should only be as tall as it needs to be to show them, but if I have 100 items then I want it to be tall enough for 10 items or for say 300 pixels and turn on scrolling. If it's shorter than the threshold I don't want the scrollbar shown at all.

We need the ability to get the next occurrence of a recurring event given a start date. This has nothing to do with the scheduler widget but a function that can take a recurring event and start date and return the next occurrence instance (not all the occurrence). We need this to tell the user when they have their next appointment.

Currently in data bound mode of the ScrollView doesn't allow filtering of the datasource.

I'd like to suggest the support of animated scrolling for the scrollTo() method of Kendo UI mobile scroller

Right now, the scrollbars of the scrollwrapper widget only show up if the user actually starts scrolling.

However, there are circumstances where the user might not be aware that the content is actually scrollable.

Two examples:

The content of the scrollwrapper contains a lot of whitespace/background such that the user sees whitespace at the end of the scrollwrapper box and is not aware of overflowing content.

The scrollwrapper does not contain continuous text but a list and the visible content ends right after a list item -- the user might not be aware that there are subsequent list items hidden in the overflow.

Thus I suggest to add a configuration option to the scrollwrapper widget which makes both/the horizontal/the vertical scrollbar permanently visible to inform the user about overflowing content.

Lets say I invoke a view like /view.html?id=123

On the "show" event of "view" I pull the data from the server based on "id", and some loading and layout stuff.

On this "view" I have a button that navigates to another view that is a "picklist", or "settings" or "help". Upon going to this second view and then going back, then the "show" event of "view" is fired again, pulling data from server and re-running all that was inside the show event again.

On some situations it is important to conserve the visual state of the view after coming back to it. For example, if user is filling a form.

The same problem is faced when you want to implement a wizard (step by step) form: pressing back will wipe out all data and reload, loosing previous screen state.

There must be a way to prevent this. I have tried the e.view._back flag of the show(e) event, but it is not always reliable. By having such flag, all the scenarios mentioned can be handled by code, by knowing when it's a fresh-show or a back-show.

I would like to see a robust data-grid for tablets.  Bring over as many features from your desktop grid into the mobile world.

Element scrolling on Android 2 devices is jerky. As a workaround it would be good to have ability revert to native page scrolling. 
I've successfully implement this with css, but this only works on non-touch devices. Touch devices "highjack" the touch events of body.

If we have a flow of 3 steps. A1 -> A2 -> A3 -> B1 I want to be able to hit back and go to A1. This is currently not allowed and we must construct flows based upon views that have to be linear forward and back. I want to be linear forward but go back differently.
