Add client-side filter method that automatically updates the filter menu options (dropdowns and values) according to the filters described in the filter expression.

Please render the text labels and checkboxes with the valid markup so that selecting the text gives focus to the related checkbox.

ie.
<span class="editor-field">
  <input type="checkbox" id="treeItem1" value="1">
</span>
<span class="editor-label">
  <label for="treeItem1">Tree Item 1</label>
</span>

ForeignKey coloumn failed to validation if option label value ("Select value") is selected.

Kendo UI layout is not working correctly in IE 7

Enhance the RTL support because if you check list view control at demo page and click RTL u will see that the pager still not switched rtl 

While KendoUI Mobile has a nice and customizable iOS switch component, based on CSS and fonts, I want to suggest including to the framework also a language independent generic graphical switch component, where the ON state has an 'I' symbol and the OFF state has a 'O' symbol. This could be used as an alternative to the current CSS-version. Purely graphical version would ensure the native looks, which you can see in my forum post attachement here:

We are using the kendo dropdown widget and noticed that the performance degrades quite drastically if it contains more than 100 items. Can you investigate performance improvements even for larger item sets?

Is there any way to implement checkbox list using kendo web?

I moved from Silverlight to HTML/KendoUI for building RIAs. One feature I am accustomed to using is the template selector. 

For instance I currently have a situation where I display an editable list of policy holders using KendoUI. However a policy holder could be a person or a business and different fields/labels should be shown depending on the source object. 

As a workaround I have conditional logic in the template itself, but it isn't pretty.

Please add template selectors for all list controls so that it is easier to style items.

This bug is visible in your demo at http://demos.kendoui.com/web/grid/editing.html.

When using a scrollable, editable grid in IE (9 or below):
•	Scroll down so that the first row of the grid is no longer visible.
•	Click on any row.
•	The grid jumps back up to the original "unscrolled" position. (In your demo, on my screen, this means that only the first 10 rows are visible.)
The result is that I am unable to edit any row outside the first 10, unless I use the keyboard to navigate.
This does not occur in Firefox, Chrome, Opera, or Safari - only in IE.

Kendo grid has default filter option .How can i integrate the grid with filtered value in chart

Please provide a way to display multi-line labels in the chart controls such as the bar chart category axis.  The need is detailed in this post:
http://stackoverflow.com/questions/13247577/line-break-in-category-label-of-kendo-ui-chart

Something similar to this: http://ui.ajax.org/#demos/elements.flowchart

Fix issued described in support ticket 634770 

It would be a great idea if the kendo ui grid has the ability to freeze numbers of columns and rows when scrolling. 

This will allow the user to have the ability to keep for example total etc to be always shown. Those frozen columns will probably not included in the sort. 

It would be nice if you added an option to actually use combobox in mvvm scenario.

Input Mask is very  basic requirment but Kendo UI dont have such Mask Controls.

The validation framework validates an input element and applies "k-invalid" class when its value is not valid to the hidden input. For such widgets like the ComboBox, DropDownList or NumericTextBox the applied k-invalid class is not applying to html-tags visible to user.

Any update on this?

By enabling the drilldown feature on charts, clicking the charts should take the user to the next level.
