HI Telerik,

We are coming over from the AJAX suite and have to say that the demos and documentation are horrible at best.

One of the greatest strength we have seen with Telerik has been your demos of almost every variation and sample most people could come by with news ones added quite often. If there wasn't a demo you were almost sure to find it in the Documentation.

The last place to look before contacting Telerik is the FORUMS but this is impossible with the way KendoUI forums use the search. It search ALL forums not just the current sub forum and pulls things back like Client Log-in pages etc.. The forum search needs to work more like the Main Telerik Forum site otherwise its impossible to use the forum unless you want to go through each forum page by page

The keno UI demos are geared towards just the client side. There is very little show how to do things with the server wrapper for MVC. It would also be nice to show the service code as well for things like the data source read, create, update and destroy events for widgets like the grid etc..

Here is a sample. http://demos.kendoui.com/web/grid/editing-custom.html
The demos shows the client side HTML version and if you choose the RAZOR syntax it is a completely different code than what is in the demo above.

The lack of documentation makes it very frustrating to use the KendoUI. New features are great but if there isn't adequate documentation to support how to implement then many features will go unused.

I hope you guys will take a serious look at the KendoUI Demo and documentation and consider making it an immediate priority to address.

Currently in Kendo UI if a user sorts a grid column and leaves the page, when they come back the sorting has been reverted. I think there should be a way to automatically save the grids sorting state (potentially in cookies) so that when a user leaves the page and comes back, the state is how they left it.

Similar functionality to the jQuery UI sortable feature.

Ability to take over the default sort and do a custom sort on the grid. This will be really helpful for formatted columns that requires a separate sort logic. 

It would be nice if you could add a disabled state for k-button.  That way, we don't have to hide the buttons from the users to force them to enter some information before clicking a button.

I would really like a ProgressBar control. The reason why I want a progressbar control in kendo ui is so that the look and feel of my application is consistent throughout.

I would suggest to enter the function menu script that is described in the following link. This is an interesting application that really makes it easy to navigate the menus user an.

Is integration with aerelia planned?

I created this suggestion in the forum, but I thought I echo the same info here for others to enter their vote.

Recently, the Telerik ASP.Net Ajax released their Q2 with a nice & powerful "Notification" control. This control can be very useful with 3 tier apps using pure Ajax to notify actions that take place on the server or web service. I suggest to consider this control for future development.

Integrate with breeze.js (www.breezejs.com/). Kendo UI needs better change tracking capabilities and unit of work support and automatic fix-up of navigation properties. Kendo UI's DataSource only deals with entities of a single type. Kendo UI's ObservableObject tracks whether an object is new or dirty, but not whether an object is deleted or detached. On removing items from Kendo UI's ObservableArray, items are not marked as deleted. Etc.. Breeze.js' entity manager deals with entities of all types, tracking their changes, fixing up their navigation properties, and submitting their changes in a single unit of work.

When we do some pages just like register, we need step by step, a smart wizard plugin will be useful.

This is a great framework that takes the best ideas of angular and react without being as difficult to learn as either of them.  Please consider it.

This would be great. It is kind of what I had in mind when I suggested this: http://kendo.uservoice.com/forums/127393-kendo-ui-feedback/suggestions/2662536-add-grid-column-filters. I currently use this type of filter where the filter is just a free text field and upon blur or enter, it runs the filter. having control over the type of filter syntax used would be great ... so that it is Linq, List, Oql, or custom string compatible. This is a common feature in the Telerik Grid when used in client mode...

For example; similar to http://www.highcharts.com/stock/demo/arearange

Having area 'scatter' support, such as 'scatterArea', and 'scatterAreaRange', like the existing 'scatterLine', is also desirable.

Grids correctly display aggregate information in a groupFooterTemplate, but it only shows this information when the section of the group-by is visible (not collapsed).

Is there a way to display the aggregate information in a template that shows when that section is collapsed?

Since now Google started doing it on Gmail, I believe that we'll need even more these features.

Excel export with image for grid

It would be a great help if there was a way to add a Trendline to a line chart in the DataViz collection.  This function is available in excel and other similar programs.  
The wiki page explains:

It would be great to have a true Timeline control for showing events overtime on a scrollable axis.
