When the user enters a filter, the list is filtered. But if the user deletes the filter by clicking on the X in the filter box, the list remains filtered. It does not revert to the full, unfiltered list. 

To get back to the full list, the user must delete the filter by backspacing or pressing the delete key on the keyboard.

This behavior is confusing some users, who have used the mouse to delete the filter in IE11.  There's no longer a filter string there, but the list is still filtered.

Can  the dropdownlist listen for the click that clears the filter string from the textbox?

Currently it is not possible to show the filter row until some data has been received and the dropdown is visible.

Please enhance/change the DropDownList widget so that it will be possible the enter a filter expression before any data is queried.

Currently multiselect increases its height to accommodate all selected values. Can you please provide a way where it reverts back to its height after selecting all values and shows 1 value and count for rest of the values selected?

Here is a screenshot:

Currently, the AutoComplete widget supports only a single separator value. It would be desirable to be able to fire an autocomplete action after multiple separators, which can be suplied as an array in the separator property of the configuration object.

Make up/down arrow keydown events fire a DropDownList change event when in the expanded state.

When a user clicks on the DropDownList, the list gets expanded. There is no change event fired for up/down arrow keydown events. I currently have to intercept the up/down keydown events manually. Having up/down arrow keydown events fire a change event would make the widget more intuitive and helpful for user interactions.

Currently when a combo box is used on an edit form, when the combo box first loads, the value property it is bound to (e.g. an int id) is displayed as the text until the databound event fires, and the text value associated with that value can be loaded.  It gives the combo boxes an unprofessional look, as they briefly display a number until they are done loading.  It also creates some other problems when you have a custom filter function, as described here:

I recognize that you would not want to change the default behavior since it would be a breaking change, but could you add a flag to toggle this behavior off.  You could add a property called "DefaultTextToValue" which is set to True by default, and if you set to false, the display would remain blank until the text value was set by the databound event.

to have Accent Folding support for kendo combo box. We are using generic html/Jquery to do this now. Is there a work around or and any suggestions.

Currently multiselect control has a change event only which is supposed to take care of add/remove event.
Please add proper events or pass info in the change event about what changed, so that developers doesn't have to write the same JS again and again.

Add a way to check if the current AutoComplete value would be in the suggestions. Since the widget already searched for the value to see if it is in suggestions I would prefer to be able to check the result of that search. Something like calling kendoAutoComplete.search() but not have it affect the UI - just tell me if it was found or not. Is that possible?

I want to be able to alter the UI if the user has entered a value that is not detected in the suggestions to let them know it is not a valid value, and it seems silly to have to manually see if the value is in the datasource (and handle the filter variants 'startsWith' and 'contains') when that is already being done by the widget. So, I'm just looking to detect whether the search done by the widget found the value in suggestions or not.

The option to allow new items to be added to the list, as opposed to items exclusively in the datasource.

For example see this: http://jsbin.com/iXEtonO/4/edit, only built in

When using IE10/11, it natively supports the clearing of input element so essentially when hovering over a Kendo ComboBox with a selected value, this is the end result:

http://i1256.photobucket.com/albums/ii484/vobreshkov/KendoComboBox_IE.png?t=1376577876

I am constantly getting requests to have such way (or adding an extra menu item) to my combo boxes to allow users to click on something and clear the selection. Please consider extending similar functionality to the combo box that is available on all browsers.

Create the ability to customize tag templates on the combobox and autocomplete widgets just like the tag template functionality on the multiselect widget

It would allow selected items(Tags) to be displayed as well as add new ones or select ones from an autocomplete dropdown.

Now autocomplete can not use to suggest email input, just like I input my name, the widget can show myname@xxx1.com, myname@xxx2.com, myname@xxx3.com like this, and the data will be only [{"email":"@xxx1.com"},{"email":"@xxx2.com"},{ "email":"@xxx3.com"}]

Check out this idea. It may help solve this issue and help with UI presentation.

Hi Support Team,

Current, we are facing a problem when using "kendo ComboBox" and options in attachment. To reproduce this issue, you have to run sample(kendoui.web.2013.1.319.commercial\examples\web\combobox\index.html) from attachment on safari of iPad.
Step by step:
1. Click on arrow icon to expand items
2. Click on textbox
3. Type data to search items near the last item on textbox

Actual: ComboBox don't auto scroll to item of user typed.

Best practice dictates that dropdowns open on mousedown, such that that user can press, move to the desired item, and release all in one movement. You'll of course find this behaviour across many apps and OS's, including MS Office, Windows and OSX. Sadly, Kendo UI dropdowns open on mouseup/click, rather than mousedown, which means the user has to do two clicks to get to what they want. For heavy-usage applications, this is a big pain for users, and definitely affects usability.

Not showing the selected items externally , only within the drop down.

Currently it seems that kendoDropDown only supports select elements with options and not optgroups. Would like to see this widget support select elements with both optgroup and option elements.
