Having the ability to generate barcodes is great, but having the ability to scan barcodes as well would make the control even better.

My mobile app requires that my data grid have frozen columns on the left that do NOT scroll horizontally.  This is useful when the first column might be an ID column or a Date column that the user always needs to see when scrolling through the other data columns.

Like in the WPF GridView control: 

https://docs.telerik.com/devtools/wpf/controls/radgridview/columns/column-groups

Occasionally the DataGrid horizontal scrolling does not work properly after changing its ItemsSource.  Still, tapping on any item, make it possible to scroll again.

Introducing a TabItem.IsTabVisible property would be useful. 

Currently, if you want to hide a tab, you need to remove it from the TabView.Items collection and cache it in a backing collection.

Then, to re-show the tab, remove it from the cache and add it back to the TabItems (preferably at the same index if you've also cached it's position).

Hi Team,

Is it possible to show the "Current Time(Red Line)- indicator" in RadCalendar. We have attached the sample image for your reference. 

Thanks,

Vinu.

When using a RadListview with a Grid or a Stack Layout in iOS I get the following exception. I haven't tested using the stacklayout outside of the RadListView nor have I tested it outside of the ItemTemplateSelector

If you download the pdf document from the internet, save it to the device and try to show it inside PdfViewer, it will not be loaded on Xiaomi phones with MIUI 12.1. and above.

Users report similar issues with downloaded files on MIUI devices, here are a few discussions on the matter:

https://www.reddit.com/r/Xiaomi/comments/l3x5db/miui_12130_broke_file_permissions_on_mi10_lite/

https://www.reddit.com/r/Xiaomi/comments/mx05ur/file_downloading_issues_on_my_xiaomi/

It seems that's the same reason for the PdfViewer not showing downloaded pdf files as it properly shows pdf documents added as embedded resource to the solution.
