when building an app with adding the Theming, there are thousands of warnings.

When the numerical column enters edit mode, in order to display the keyboard you need to tap one more time.

Outside of the datagrid, when the numeric input control gets focused, the keyboard appears.

Expose an API to explicitly set the popup position (on which side the popup should be displayed).

Currently, there is a logic that automatically detects the available space and opens the drop-down above or below the input field.

Is it possible to be implemented like you have on TreeView -> https://www.telerik.com/maui-ui/documentation/controls/treeview/load-children-on-demand 

when having the following format in cultures where there isn't a space for am/pm and time:
tth:mm or h:mmtt 

the spinner does not display as expected

for example such culture is Chinese (Taiwan) the am/pm and hour spinners are missing:

1. Open the drawer, the app being in portrait mode.

2. Seen that the background is faded out.

3. Change the orientation to landscape mode.

4. ISSUE- Seen that the fade is not covering the screen fully as per the landscape view.

Null reference exception occurs when measuring the cells container:

when setting Telerik PlatformDark and PlatformLight themes, the DataPager_PageSizesView_LabelText  localization string of the DataPager does not apply. 

 

Workaround: Use the Telerik themes

Please add support to move the caret in Richtextbox to the beginning of the document.  

Provide an API that allows control over item highlight behavior during filtering. Specifically, if the search text does not match any item, no item should be highlighted, and pressing Enter should not trigger a selection.

For example IsCheckedChanging event with e.Cancel

Similar to the Indicator and FilterIndicator, they both expose FontOptions - FontFamily, FontAttributes and FontSize properties. Provide such for the SortIndicator.

Calling Focus(); does not focus the control. 

When items are added to a collapsed group in the DataGrid, they are not marked as collapsed internally, which causes gaps to appear at the bottom of the control. These items are still considered during the measure phase, resulting in an inaccurate height calculation for the row content.

NullReferenceException occurs when they click on an AutoComplete item other than the first one on macOS, using a mouse or trackpad.

jittering occurs when scrolling through the data and having binding in the footer text, expanding the row details and live data update.

When setting GroupAggregatesAlignment NextToHeader and the column size mode is stretch or auto, the aggregates text in the group header is misaligned, part of the text enters in next column when data changes.

 

when the column is resized or datagrid is scrolled, the aggregates are aligned as expected
