How to apply SelectedRowTextColor to the cells of a DataGridTemplateColumn in MAUI DataGrid (SfDataGrid)?

The current implementation of the MAUI SfDataGrid, the SelectedRowTextColor would not apply to the cells of DataGridTemplateColumn. This article illustrates how to apply SelectedRowTextColor for DataGridTemplateColumn cells in a .NET MAUI DataGrid.

• Initialize the SfDataGrid with the required properties, such as ItemsSource, SelectedRowTextColor in the SfDataGrid.DefaultStyle, and use DataGridTemplateColumn for the required columns.

• Write a custom renderer class that extends from the DataGridCellTemplateRenderer class. In the overridden OnSetCellStyle method, check if the respective row is present in DataGrid.SelectedRows. If it is, set the SelectedRowTextColor for the content of the DataGridTemplateColumn cell; otherwise, set the RowTextColor to the text color of the content.

• To register the custom cell template renderer with the SfDataGrid.CellRenderers collection, remove the existing entry by its key and then add a new entry with the same key, along with an instance of the custom renderer.
