It seems that the default fonts in the RadDataGrid do not support some languages, for example this text "이름" cannot be displayed in Android and WinUI. Rectangles are rendered instead of the correct symbols.
Note that a maui Label can properly display the text.
We’ve encountered an issue related to the inner DataGrid within an outer DataGrid’s RowDetailsTemplate:
Steps to reproduce:
1. Create a DataGrid with editable cells and row details.
2. Inside the RowDetailsTemplate, place a layout (e.g., Grid).
3. Within this layout, embed another DataGrid with editable cells.
4. Start the application and expand row details on the Android platform.
5. Double-tap on any inner DataGrid's cell to open the cell editor.
At this moment the UI appears unresponsive.
The DataGrid Search As You Type feature provides search text highlighting through the CellContentStyle property of the columns.
CellContentStyle is taken into account only for the default columns, so when you specify a custom CellContentTemplate or use a TemplateColumn currently the search text highlighting is not applied.
