Take this Dojo: https://dojo.telerik.com/iCECeXeC

1. Press 'Run'
2. Remove the filter for Contact Title
3. Press 'Save State'
4. Reload page (F5)
5. Press 'Run'
6. Press 'Load State'

Result: The filter for Contact Title is not removed.

On the other hand if I do the following:

1. Press 'Run'
2. Change the filter for Contact Title to 'Sales Representative'
3. Press 'Save State'
4. Reload page (F5)
5. Press 'Run'
6. Press 'Load State'

Result: The filter for Contact Title is changed correctly to 'Sales Representative'

Why is the first example not working? Is this intended behaviour or a bug? Is there a workaround?

Kind regards.

Starting from a Grid's "endless scrolling demo" on: https://demos.telerik.com/kendo-ui/grid/endless-scrolling-remote

Edit grid configuration to set smaller page size. All items of the first page need to be visible on the screen plus some free space. A grid height needs to be set. See this DOJO: https://dojo.telerik.com/amiNohIx

The vertical scroll bar is disabled and there is no way to get/see next pages of data.

Interesting is that use of the horizontal scrollbar (if one is available) starts some background operation (looks as data page load) and then the vertical scrollbar is OK.

Dear support,

I've found a bug in kendo ui grid concerning the combination of grouping, multi-column headers and showing/hiding columns. To reproduce the issue, please use the "Multi-column headers" demo on your kendo ui demos page. Now please use the column menu to hide both child columns of the 'Locatiion' column header ('Country' and 'City'). Now please group the data by the column 'Contact Title'. If you now use the column menu to show one of the previously hidden columns (e.g. 'Country'), you will see that it is shown at the wrong position (left site, index 0).

I've attached an image showing the issue.

Kind regards

Iggy 

Since the 2019 R1 release k-pager-sm (k-pager-lg, k-pager-md) classes are assigned dynamically based on the width of the page to make the component responsive (as I understood from https://www.telerik.com/forums/kendo-ui-grid-pager-not-displaying-properly-in-sass-mode#wn92di5BakmHqrrMfViFxA)

When grids are used on bootstrap tabs (both boostrap 3 and 4) the k-pager-sm class is added incorrectly, causing the pagers on tabs other than the first to be displayed only partially.

A JSFiddle to demonstrate this: https://jsfiddle.net/nqjc4mbu/

The pager on the 1st tab:

And on the 2nd and 3rd tab:

(we've solved it with a workaround by dynamically removing the k-pager-sm class again on dataBound, but this shouldn't be necessary)

Dear Kendo-Team,

When using the less-based Bootstrap theme, the PDF export of a grid shows strange borders underneath header's column menus. Refer to the following DOJO for replication:

https://dojo.telerik.com/ePOSiluT

Enclosed you will find a screenshot of the PDF export, showing the strange borders.

Is this something we can easily (temporarily) fix on our own by adjusting some CSS styles?

Bye

Ralf

We would like to add a new column(s) dynamically to a grid, This feature is very important when grid containts lots of fields. In order to resolve slow grid rendering, we are allowing user to choose columns to show/hide and render grid accordingly. Kendo generates html code for hidden columns which causes slow rendering for large data. We are already using performance improvement suggestions from kendo like virtual scrolling, paging etc.

Bug report
Аggregates not working in group footer, when string value contains line break "\n"

Reproduction of the problem
Dojo: https://dojo.telerik.com/uPuyEcEJ

Current behavior
Аggregates not working

Expected/desired behavior
Aggregated should be working fine when the value contains "\n"

I'm trying to test the accessibility of the grid detailTemplate on https://demos.telerik.com/kendo-ui/grid/detailtemplate , namely keyboard navigation.

Honestly, I don't even know where I am. I know when I'm focused on the button "Edit in theme builder" (it's barely visible, but visible), and when I press tab, document.activeElement points to the first table header ("Last Name"), but it's not visible at all. Then I keep getting lost.

I have tested it with all sass-based themes and the less-based Material theme.

Hi Team,

I am using the Kendo UI version [kendo/2020.1.114] and CSS - [kendo.default-v2.min] for adaptive rendering.  I am  facing issue to use Kendo Grid Adaptive Rendering feature in our Application as I am using KendoComboBox  to bind String type fields and KendoNumericTextBox for Decimal and Integer  type values. These are all working fine in WEB view but not working in Mobile View. All the kendo input controls are converted into normal html controls in Mobile Mode and break the KendoComboBox and NumericTextBox  by default feature in Kendo Grid Filter and numeric textboxes also allowing to input string values. So Please look into and help us to resolve  this problem.

Thanks

It would be great if the selected operator could be made visible in a filter row. For instance when I select the operator "Is greater than or equal to" the filter button icon should reflect this operator option. Something like this:
