Hi team,

When deploying to certain platforms, under cetain circumstances, there is an exception that occurs in the DatePicker, TimePicker and a few other controls that rely on the same inner components. The stacktrace looks like it has to do with a default value for AppThemeBinding.

Thank you,

Nathan

SDKBrowserMaui application, change PopupStyling.xaml and see that text changes are not reflected in the control.

For example, changing it to:

            <Style TargetType="Button" x:Key="cancelButtonStyle">
                <Setter Property="BackgroundColor" Value="Transparent"/>
                <Setter Property="Text" Value="bob"/>
                <Setter Property="TextColor" Value="#1188FF"/>
            </Style>

Text is not applied. It affects all pickers.

Workaround: 

Set Accept and Cancel Button text properties to the pickers: 

<telerikInput:RadDatePicker >
            <telerikInput:RadDatePicker.SelectorSettings>
                <telerikInput:PickerPopupSelectorSettings 
                                                          HeaderLabelText="Date Picker"
                                                          AcceptButtonText="Yes"
                                                          CancelButtonText="X"/>
            </telerikInput:RadDatePicker.SelectorSettings>
        </telerikInput:RadDatePicker>

When setting BorderBrush, BorderThickess, FocusedBorderBrush and FocusedBorderThickness do not apply on the entire entry control, they apply only on bottom. 

<VerticalStackLayout>
    <telerik:RadEntry Text="Hello World" TextColor="DarkRed" 
                        Background="Wheat"
                        FocusedBorderBrush="Yellow"
                        FocusedBorderThickness="10"
                        x:Name="entry" 
                        BorderBrush="DarkRed"
                        BorderThickness="8"
                        CornerRadius="5,7,7,5"
                        WidthRequest="150"/>
</VerticalStackLayout>

And the result:

Hi Team,

Please refer to the following screenshot from the ControlsSamples project on Windows:

Notice the descender on the y character is pushing up the Delivery column header's Label container, but the Price text is flush with the bottom? This is causing misalignment between text in other column headers that do not have descenders.

You might not immediately notice this, for example in the Aggregates demo, only the first column has no descenders but the next two do. 

 

However, it's a more serious visual problem when every other column is vertically offset. Please consider adding a default Padding to account for descenders, or maybe change the VerticalOptions of the text container to be center aligned.

Thank you,

Matthew & Team

BackgroundColor is not applied property when DynamicResource is used and button enabling state is changed

<Style TargetType="telerik:RadButton" x:Key="MyTelerikButtonStyle">
            <Setter Property="TextColor" Value="{DynamicResource MyPrimaryColor}" />
            <Setter Property="BackgroundColor" Value="{DynamicResource MySecondaryColor}" />
            <Style.Triggers>
                <Trigger TargetType="telerik:RadButton" Property="IsEnabled" Value="false" >

                </Trigger>
            </Style.Triggers>
</Style>

WORKAROUND:

Use StaticResource:

 <Setter Property="TextColor" Value="White" />
 <Setter Property="BackgroundColor" Value="Green" />

Hi,

I'am testing Telerik .NET MAUI controls for windows and android. FontFamily property of columns (both for xaml and app.xaml) not working. If an embedded font is choosen for whole application, DataGrids look different from other parts of the application

here is my xaml, "fnt_bold" is a MauiFont in resources. All other ui components are shown in my font

                <telerik:RadDataGrid x:Name="dataGrid" AutoGenerateColumns="False" UserEditMode="None" UserGroupMode="Disabled" SelectionMode="Single" SelectionUnit="Row"  >
                    <telerik:RadDataGrid.Columns>
                        <telerik:DataGridTextColumn PropertyName="ID" HeaderText="RefID" Width="60" SizeMode="Fixed">
                            <telerik:DataGridTextColumn.CellContentStyle>
                                <telerik:DataGridTextCellStyle FontFamily="fnt_bold" FontSize="12.25"/>
                            </telerik:DataGridTextColumn.CellContentStyle>
                        </telerik:DataGridTextColumn>
                        <telerik:DataGridTextColumn PropertyName="CODE" HeaderText="Code" Width="80" SizeMode="Fixed">
                            <telerik:DataGridTextColumn.CellContentStyle>
                                <telerik:DataGridTextCellStyle FontFamily="fnt_bold" FontSize="12.25"/>
                            </telerik:DataGridTextColumn.CellContentStyle>
                        </telerik:DataGridTextColumn>
                        <telerik:DataGridTextColumn PropertyName="NAME" HeaderText="Name" Width="250" SizeMode="Fixed">
                            <telerik:DataGridTextColumn.CellContentStyle>
                                 <telerik:DataGridTextCellStyle FontFamily="fnt_regular" FontSize="12.25"/>
                            </telerik:DataGridTextColumn.CellContentStyle>
                        </telerik:DataGridTextColumn>
                    </telerik:RadDataGrid.Columns>
                </telerik:RadDataGrid>

I have attached a screenshot from my test app.

I also checked the sample telerik android app (Telerik UI for .NET MAUI Controls). DataGrid components in Telerik Sample app also dont use the expected font unlike all other ui components.

Just one of the DataGrid samples of one column in the sample app has the correct fontfamily property. I have attached that screenshot also. I couldn't figure out how to implement it.

Am i missing something?

Thanks in advance.

Ender

I have a DataGrid with ItemsSource bound to ObservableRangeCollection,
First I Clear() the existing items of the collection, then add new items, and raises a single CollectionChanged event with action = NotifyCollectionChangedAction.Reset.

the grid continues to show nothing.

This works with .NET MAUI CollectionView and ListView

Workaround: Add a delay after clearing the collection.

Popup:

Calling

IsOpen = true,
IsOpen = false,
IsOpen = true,
IsOpen = false,

while the last IsOpen update isn't ready, kills the Popup.
It works async, even if animations are set to none/0s and there is no public event to validate the last update is fully done (Popup opened/closed)

In my case i have a popup opened, while a search operation is running in the background.
If this background search returns too fast and i set IsOpen to false, the update is ignored and the popup keeps in an opened state.

The following code uses RadHighlightedLabel and manipulates the highlighted text by the Text of an Entry.

<telerik:RadDataGrid x:Name="dataGrid" AutomationId="dataGrid" AutoGenerateColumns="False">
                <telerik:RadDataGrid.Columns>
                    <telerik:DataGridTextColumn PropertyName="Country" HeaderText="HighlightedLabel">
                        <telerik:DataGridTextColumn.CellContentTemplate>
                            <DataTemplate>
                                <telerik:RadHighlightLabel UnformattedText="{Binding Country}"
                                                                           HighlightText="{Binding Source={x:Reference searchEntry}, Path=Text}"
                                                                           HighlightTextColor="Red"/>
                            </DataTemplate>
                        </telerik:DataGridTextColumn.CellContentTemplate>
                    </telerik:DataGridTextColumn>
                </telerik:RadDataGrid.Columns>
            </telerik:RadDataGrid>

Expected: When typing in the entry the text of the label should get highlighted and remove the highlight when the text of the entry is removed.

Actual: The highlighted text doesn't get updated and stays the same.

When the selected item is set initially, the selected style is not applied to the row/cell.

Workaround: You can use a Dispatcher to workaround the issue, code looks as follows:

this.Dispatcher.StartTimer(TimeSpan.FromMilliseconds(200), () =>
        {
            if (dataGrid.SelectedItem == null)
            {
                dataGrid.SelectItem(viewModel.PersonCollection.First());
            }
            return false;
        });

1. filter the column by any distinct value
2. The filter is applied
3. Open the same filtering again and tap reset
4. All rows are visible and everything is ok
5. Open the same filtering again

The Checkbox from step 1 is still checked and checking any other checkbox and applying filtering does not work

On Android: RadEntry and .NET Maui Entry behavior are identical. When unfocused, the focused background is still applied.

On WinUI: RadEntry and .NET Maui behavior when are unfocused, the focused background is still applied. When RadEntry is in the "Focused" and "PointerOver" visual states, the control behavior is with the default state. When .NET Maui Entry is in the "Focused" and "PointerOver" visual states, the control behavior is with the "PoinetOver" visual state.

On iOS and MacCatalys: When RadEntry is unfocused, the focused background is still applied.
