I am using ASP.NET MVC and implemented Kendo Grid Inline Add/Edit/Delete functionality.

I am binding data source from server side first time. Then I do Add/Edit/Delete operation on client side in kendo grid data source property.

When I Edit any row which has been added temporary, then I do cancel click , the row is getting deleted automatically from the data source itself. 

The row should be persisted in the datasource. please let me know any solution for this issue.

In one of the more recent builds a Frozen Columns feature was introduced. However, the feature is currently not supported for hierarchical grids. We were wondering if it would be possible to implement an enhancement which would support both of these features simultaneously.

I want to be able to right click on a point in the line graph and add an annotation or expose a menu for them to choose. The scenario is I want to right click on a point and say the value of that data point is invalid.

I am trying to programmatically remove selected items from a multi-select control unsuccessfully. The idea is that we have placeholder items that when selected, automatically populate items without requiring the user to select each one individually. So far, I have been able to remove them by clearing the filter and replacing the control's value property. The problem is that when I return back to the control the placeholder item I had removed re-appears. I have also tried applying the same logic to the dataitems property. I also tried to figure out how to overwrite or cancel the change event all without success. I have spent several hours now trying to add this functionality and am frankly a bit frustrated. I am also now examining other attributes/properties of the control to see if I can determine how/where the control is remembering the previous item selected. Any help would be greatly appreciated.

I need notification hiding to be passed when hovering over a notification.

To further explain I am expecting a behavior such in following example.

1. A color should already be set using the UI tool, and you also need the ability to set the color using a hex value
2. Load the color control
3. Change the color to something and apply using the gui color selector controls
4. Save your change
5. Edit the color again
6. Specifically set the color using "#99B8E6"
7. You may need to try to set it to that color "#99B8E6" several times, but after a couple tries UI controls will override your specifically entered color selection to something that is close to that color, but not exactly the color you intended.

Have a render mode that will display the listview items responsively.

This could also play nicely with a mobile version of listview.

Sometimes there is a delay between when a user interacts with a widget and when something actually "happens".  This is especially evident on mobile apps (e.g. AppBuilder) when there are complex bound value changes/dom changes.

An example would be clicking a button in a ButtonGroup to display a ListView that uses a remote bound DataSource which displays images and text in the list.  Sometimes, in scenarios such as this, you'll click on the button of the ButtonGroup and nothing will happen for a few seconds.  This makes for a poor user experience.

Since we can't make the app react instantaneously we really need to at least make it appear that it is or else the app feels "slow".  Though some Kendo Mobile widgets attempt to aid with this by using the application.showLoading() when engaging in a "long" process, even that will ofen have a delay before showing.  I'm not sure why that is, maybe it's due to the order in which it is processed.

In any case, the first thing that every widget should do before anything else is indicate to the user that "yes, I acknowledge that you just clicked/tapped me and I am working".  An example of this is in iOS native apps when you are trying to delete an application.  As soon as you click the "x" to uninstall the app, it turns gray, even though it may take a few seconds before the app actually uninstalls.  If all Kendo Mobile UI Widgets gave feedback instantaneously, that would go a long way to covering up some performance issues that might exist with the framework.

Right now it seems to support only Shapes and Textboxes, what plans do you have for supporting Charts and perhaps any plain HTML (that would then be possible to "kendoify")?

I just want DataViz. I'd be happy to pay for the professional license, but I don't want all of the widgets and have to install everything. And please, make this manageable through Bower. 

Add required validation support when using radio buttons. This is currently not supported out of the box. Ideally only one radio button in a group should need the required attribute, not all of them.

See forum post below for more information:

The "Drag and Drop" system in Kendo is pretty good, but it has the distinct characteristic of being pretty much DOM only; It won't really "bind" to underlying data.

This would be an extremely useful feature - the "suggested fix" for this right now is to use the kendo ListView and do a search for GUID on the events firing, and while this isn't really "bad", it's pretty cumbersome and kind of obtuse most of the time.

I have spent extensive time looking at the source code for Drag and Drop, and it would not be very difficult to give it a newly exposed set of functions. 

The primary use for drag and drop is to move information from one place to another; I do not see a lot of situations where all of the information someone wants to move is just right there in the DOM. Every situation I see of Drag and Drop that people want to use involves moving DATA from one place to another, and the Drag and Drop on the DOM merely facilitates the actions in place of more cumbersome features like drop down lists.

I realize this isn't the easiest of tasks to do, but as it is right now, the Drag and Drop part of Kendo is more of an eyecatch than a feature I see used a lot. 

I use the QR Code control in the Silverlight controls quite often and would love to be able to use something similar with Kendo UI.

For example, if one wants a conditional on positive, negative, and zero values, one can use such format "{0:N2};neg{0:N2};no value". Search in the link for Section Separator

The currently existing 'validate' event is only triggered on submit of the form or by developer code. Ideally, an event should be available that is raised by any unobtrusive validation event.

Ádd new event to the Validator, raised by validateInput. This will allow custom handling of validation errors, even when the user is not trying to submit the form.

Usage : for example, toggling bootstrap 'has-error' class on the parent element 'form-group'. 

There is a bug that came out of nowhere. When the drop down list is selected, the position of the box with the options below that popups is not attached to the the drop down list above. I hope you understand what I mean. I can also post a screenshot. The only thing I do is to write an html select with some options and just stype it with $("#name").kendoDropDownList();

Since KendoUI has now MaskedInput widget would be nice to have a grid configuration option, which allows to specify mask for a column in edit mode.
