When starting a cell edit, it is desired to have all the text selected, so the user can easily replace the current text without having to delete it.

Refer to the attached reproducible.

1. Run app and apply a filter: "Contains 0"

2. Notice #40 is in the correct location, between #30 and #50

3. Press the button on the bottom of the page to go BlankPage and then navigate back.

4. Observe #40 is now at the end of the rows even though the filter is clearly applied.

Look in MainPageViewModel.cs lines 42 to 49. When the navigation back occurs, this code is executed.  I can reproduce the problem with both Replace and Add+Remove operations.

public override void OnNavigatedTo(INavigationParameters parameters)
{
    base.OnNavigatedTo(parameters);

    if (!parameters.ContainsKey("from"))
    {
        var items = new ObservableCollection<MyModel>();
        for (var i = 1; i <= 100; i++)
            items.Add(new MyModel { Number = i.ToString() });
        Items = items;
    }
    else
    {
        var item = Items[39];

        // Bug Test #1 - using ObservableCollection Reset
        Items[39] = item;

        // Bug Test #2 - using ObservableCollection Remove & Add
        //Items.RemoveAt(39);
        //Items.Insert(39, item);
    }
}

If you define a PropertyGroupDescriptor in XAML or in page constructor and the PropertyName is set to a nested property, the grouping is not applied.

Grouping by a nested property works correctly when called from the Filtering UI or on a button click action.

It would be nice if we can just bind a .net DataTable or DateView as ItemsSource to the RadDataGrid.

Column names in column selector are not visible in Android the first time the column selector is shown. This happens only in the case UserFilterMode is disabled.

when using automatic column generation you don't have easy access to the column being created so that you can apply customizations (Header, style, etc).

Please implement the same event that UI for WPF has, see it here: https://docs.telerik.com/devtools/wpf/controls/radgridview/events/column-resize-event#autogeneratingcolumn

When the DataGridPickerColumn ItemsSource property is bound to a collection not part of the business object used for the DataGrid, and ItemDisplayBindingPath is used, null reference exception is raised when selecting items in the picker.

Workaround for GroupHeaderTemplate:

<grid:RadDataGrid.GroupHeaderTemplate>
    <DataTemplate>
        <Label Text="{Binding Group.Key}"/>
    </DataTemplate>
</grid:RadDataGrid.GroupHeaderTemplate>


Workaround for column:

<telerikDataGrid:DataGridTemplateColumn HeaderText="Name" >
    <telerikDataGrid:DataGridTemplateColumn.CellContentTemplate>
        <DataTemplate>
            <Label Text="{Binding Name}"/>
        </DataTemplate>
    </telerikDataGrid:DataGridTemplateColumn.CellContentTemplate>
</telerikDataGrid:DataGridTemplateColumn>

 
UPDATE:
We have decided not to change the code of the RadDataGrid component in this regard. The root reason for this is the fact that the Skia APIs used to draw the text does not support automatic character fallback. To overcome this issue, people from Skia team have two suggestions. We have tested them out and none of them is applicable for the case of the DataGrid.
First approach slows down the performance of the component to a point where the DataGrid becomes unusable.
Second approach does not fix the problem in all cases.
Having this in mind the best approach for our customers in such cases is to use a TemplateCell with a Label inside it only for the column(s) where they expect symbols to occur. The Xamarin.Forms.Label supports automatic character fallback hence it should properly handle all cases.

Applying custom filter to the datagrid and removing column at the same time disables the horizontal scrollbar - in scenario when the content of the column is bigger than the screen size.
