Hi,

I updated my project to Kendo UI for jQuery 2020.3.1021 but then all Grids stopped working on mobile or tablet devices. When downgrading to 2020.3.930 grids works fine. Also tried it with 2020.3.1028 but same issue.

I have tested it on iPad, iPad Pro, Samsung S10. Same issue with Chrome/Edge Chromium and emulate a mobile/tablet device.

In the browser console you can see the javascript error: "Cannot read property 'rows' of null".

Reproduction of the problem:

1. Go to https://demos.telerik.com/kendo-ui/grid/index
2. Hit F12 top open the Developer toolbar
3. Click on "Toogle device toolbar" (CTRL + SHIFT + M)
4. Choose any device, ex: iPad, iPhone
5. Reload page to make the changes take effect
6. Click on "Run live demo"
7. Grid not loading!!
8. Console is showing a JavaScript error: "Cannot read property 'rows' of null"

Hi Team,

I'd like to request the functionality to allow the user to select the ALL option while using GroupPaging.  

Thank you

When there are a lot of columns on the page and a column is shown, it is shown at its original position in the grid columns array. 

It would be much better from a user experience point of view if the column is shown where the user clicked on the column menu to show the hidden column.

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:

Hi, 

I would like to request the configuration of the Search Panel to have a custom search function.  For example, I could use this to modify search results(ie. ignore accents).  

Thank you!

Issue that I have can be observed on any grid with checkbox selection and filtering enabled at the same time (I edit this demo https://demos.telerik.com/kendo-ui/grid/checkbox-selection by adding filtering an already I can see my problem).

I have a grid with 10 records with checkbox selection, filtering and "persistSelection" option enabled. I select a single record with a checkbox. I use filtering and only 5 records remain visible, selected record is not visible (didn't match the filter). When I clear the filter my selected record remains checked. If I do the same but filtering causes all records to disappear then after clearing the filter my selected record is no longer checked. So we can see that selection persistence works differently depending on results of filtering. That is confusing and looks like a bug.

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
