We have a requirement for the Grid to support sticky rows when virtual scrolling is enabled. I know it is documented as a known limitation on https://www.telerik.com/kendo-vue-ui/components/grid/rows#known-limitations but we would like to request the grid add this feature. We would also like to request this feature using grouped data, as I see it also is not supported in this scenario. 

One specific scenario is we have 2 groups and both groupings are sticky. The first group would have a few rows of data, while the second group has hundred or thousands of rows. We would like to allow for row virtualization on the second group while keeping the first group sticky at the top. Below is an example screenshot where we have the first "Benchmark" group having one row, the second "Investments" group having a sticky "Total" row at the top, and then rows of data that can be rendered with row virtualization to paginate. 

Provide support for custom edit items like in KendoReact. This will allow the customization of the removeDialog and the occurrenceDialog, and much more.

How to add grid footer (one row with one cell for all columns). When I try to use grid cell footer template I can't pass colspan to it (to normal cell I can). When I build template for normal cell it replace whole <td> section. When I do it same for cell footer the template content is placed inside predefined <td> - I can't replace it by my code like in normal cell. 

Can You add grid footer for all colums or fix footer cell template to work like regular cell template?

Describe the bug

After inserting an image using the "Insert Image" tool it is possible to add a hyperlink to it using the "Insert Hyperlink" tool.

If the image's dimensions are then edited by selecting the image and using the "Insert Image" tool, the hyperlink that was added no longer exists.

Before:

After:

To Reproduce

1. Open https://codesandbox.io/s/elegant-parm-l7w93g
2. Right click the image in the editor, you should see the option to open the link.
3. Select the image
4. Open the "Insert Image" tool
5. Change the width or height to another value (e.g. width -> 200px)
6. Click the insert button within the tool
7. Right click the image in the editor, you should see the option to open the link is no longer there.

Expected behaviour

The image should retain any hyperlinks that have been added even if it is resized.

Describe the bug
The following warning appears when using the InsertTable tool of the Native Editor:

[Vue warn]: Component emitted event "tableinsert" but it is neither declared in the emits option nor as an "onTableinsert" prop

NOTE: The warning won't appear when the project is built for production but, still this issue should be fixed

To Reproduce

1. Open this StackBlitz example
2. Insert a random table using the InsertTable tool
3. Check the browser's console

Expected behavior
No warnings should appear when using the InsertTable tool

Screenshots

When starting he component, to load the initial value, the Api returns the id selected as a string ("2") and DropDownList does not display the selected option. Changing the value to an integer (2) displays it correctly.

This issues requires changing the values before padding them to component, but I would  that the component parse automatically the comparision, or allow us handle the strict comparision

Make the previous/next buttons of multi-day events functional like in the Telerik UI for ASP.NET AJAX control:

Describe the bug
A licensing warning may continue to appear in the browser's console, no matter whether the licensing activation has been successful or not.

The issue is replicable when the user trying to activate a license has had an active license in the past and this license is already expired.

To Reproduce
Because of the specifics of the issue, a project in which the bug can be replicated won't be publicly provided.

Expected behavior
The license activation process should activate one's license no matter the previous licensing history of the user

Describe the bug

1. Open this StackBlitz example.
2. Select "Fish"
3. Select "Pizza"
4. Repeat steps 2 and 3 multiple times
5. See the white space in the popup

Expected behavior
