The finnish translations are not correct in the calendar component. We would like to change the translations for names of days and month, in the calendar component. As far as we know, this is not possible. We can only change 4 texts (4 calendar views localization keys) according to this documentation: https://docs.telerik.com/devtools/xamarin/controls/calendar/calendar-localization

Localization works, and we can set the language. But for the finnish language, the translations you provide for days and months are not correct. We would like to be able to change these texts ourselves, name of days and months. Is there any way for us to do this? We need the Finnish translations to be correct.


Thank you!


Best Regards,

If you use a TrueType font for the DataGrid column's OptionsButtonFontFamily, it is not respected and falls back to a default OS font.


The only workaround at this time is to create a custom column HeaderTemplate with a custom options button and hide the default options button.

<dataGrid:RadDataGrid x:Name="dataGrid" ...>
        <dataGrid:DataGridTextColumn x:Name="productNameColumn" PropertyName="ProductName">

                        <Label Text="Name" TextColor="Black"/>

                        <Label FontFamily="MyCustomFont.ttf#MyCustomFont"
                                    TextColor="Orange" HorizontalOptions="End" HorizontalTextAlignment="End" Grid.Column="1">
                                <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"/>
                <dataGrid:DataGridColumnHeaderStyle OptionsButtonFontSize="0" FilterIndicatorFontSize="0"/>

In the code-behind, we use reflection to access the column's command context and invoke the options menu via DataGrid command service.

public partial class YourPage : ContentPage
    private readonly MethodInfo generateOptionsTapContextMethodInfo;

    public YourPage()

        this.generateOptionsTapContextMethodInfo = this.dataGrid.GetType().GetMethod(
            BindingFlags.NonPublic | BindingFlags.Instance);

    private void TapGestureRecognizer_Tapped(object sender, EventArgs e)
        if (this.generateOptionsTapContextMethodInfo != null)
            // Get a reference to the column, this is needed to invoke a command
            var context = this.generateOptionsTapContextMethodInfo.Invoke(
                new object[] { this.productNameColumn });

            // Invoke the command service that opens the options button

When you place a Label with TextType set to "Html" inside ListView TemplatedCell, the ListVIew renders only the items currently in the viewport - if you scroll down, the listview is empty.

The horizontal scrollviewer is not visualized initially when the column header text is longer than the columns' text. Still, tapping on any item makes it possible to scroll.

For example: When I enable DataGrid LoadOnDemand it's loading infinitely for a static list of 3 records.

All columns cannot be scrolled with the mouse wheel. Dragging the columns with the mouse kind of works, but extremely slowly, to the point of being unusable; plus, it's not intuitive.

Changing a property on an item that is involved with grouping and sorting and then removing and re-adding the item to the collection results in the list being in an invalid state (e.g. duplicate items, incorrect template, etc.)

Error message can be reproduced on iPhone 11 Simulator iOS 13.6 

[UICollectionView] Invalid update: invalid number of items in section 0.  The number of items contained in an existing section after the update (4) must be equal to the number of items contained in that section before the update (4), plus or minus the number of items inserted or deleted from that section (1 inserted, 0 deleted) and plus or minus the number of items moved into or out of that section (0 moved in, 0 moved out). - will perform reloadData.
