Hi Dmitry,
The DataGrid can be sorted through the UI or programmatically. When tapping on the column header, you can sort the DataGrid through the UI.
In order to sort the DataGrid programmatically, you need to add the descriptors in code after setting the DataGird ItemsSource
this.dataGrid.SortDescriptors.Add(new PropertySortDescriptor() { PropertyName = "Name", SortOrder = Telerik.XamarinForms.Common.SortOrder.Ascending});Could you please share what will be the target operating system of the application? Do you prefer specific operating system or the app will target Android, iOS, macCatalyst and Windows?
I look forward to your reply.
Regards,
Didi

Hello Dmitry,
We have tested the SortDescriptor property and actually when it is attached to a TemplateColumn, the Column is not initially sorted. If you tap on the column header, then you can sort the column.
I have logged the initially sorting behavior on your behalf in our feedback portal. Follow the item at this link: https://feedback.telerik.com/maui/1554359-datagrid-templatecolumn-is-not-initially-sorted-when-sortdescriptor-is-applied Find your Telerik points updated as a small sign for bringing this to our attention.
Solution:
In order to sort the template column initially:
1. add the SortDescriptor to the Template column in XAML:
<telerikDataGrid:DataGridTemplateColumn.SortDescriptor>
<telerikCommon:PropertySortDescriptor PropertyName="Age" />
</telerikDataGrid:DataGridTemplateColumn.SortDescriptor>2. then execute the ColumnHeaderTapCommand on the TemplateColumn in code behind, inside the Page's constructor, after setting the DataGrid ItemsSource:
this.dataGrid.CommandService.ExecuteCommand(DataGridCommandId.ColumnHeaderTap, this.dataGrid.Columns[1]);
The ExecuteCommand receives two parameters, the first is the DataGridCommand id and for the second parameter - the column index where the command will be executed. In my case the template column is on index 1.

Didi
