Data Form Editors expose the property EditorStyle to allow setting the input control's overall style. But some input control have multiple styles not so easily set.

As the input control is also the Editor's base content, instead exposing content as the appropriate type allows all of the input controls styles to be set.

Here is my working example in my KingdomContacts app for one editor:

namespace KingdomContacts.Controls;
using Telerik.Maui.Controls;
public class KcNumericDfEditor : DataFormRadNumericEditor
{
    public RadNumericInput? Editor => base.Content as RadNumericInput;
}

I have made similar adaptations for all the other Data Form editors I use. Simple and easy to work with; far easier than guessing what to do with EditorStyle.

Would be even easier if a similar line were inside your editors -- then I would not need to make my own customizations.

When I compile my project with <WindowsPackageType>None</WindowsPackageType> option, icons ar enot displayed in Telerik controls (like richeditor)

Same project compiled with package  and deployed are ok

During data binding, the busy indicator freezes.  This is not a problem with the MAUI ActivityIndicator, however. See the attached video

I created a repo here to reproduce the issue: https://github.com/kklose23/busyindicator-freezing

Note:  I know there's ways to make the data binding in that repo more efficient.  I just wanted a good example.

When the Source of a RadRichTextEditor is set, the TextColor is always black.  Tested on Android:

  <Grid HeightRequest="400"
        WidthRequest="300">
    <telerik:RadRichTextEditor x:Name="RichTextEditorControl"
                               Source="with source text"
                               TextColor="White"
                               BackgroundColor="Green" />
  </Grid>

I have an html file with <img src="./images/ForkliftGateMainPage.png" alt="MainPage" width="1600" title="Page principale" />

The image is displayed when I open it with my browser, but not displayed with RadRichtextEditor, Why ?

When updating to .net8 the following snippet doesn't work with target net8 (maui 8.0.3). Same works with net7 (up to 7.101).
Stops me from targeting net8.

<telerik:RadListView.FooterTemplate>
    <DataTemplate>
        <Grid
            BackgroundColor="{AppThemeBinding Dark={StaticResource ListElementColorDark},
                                              Light={StaticResource ListElementColorLight}}"
            IsVisible="{Binding CanSearchMore}">
            <telerik:RadBorder Padding="8,10" Style="{StaticResource ListItemContainer}">
                <Label HorizontalOptions="Start" Text="{Binding SearchMoreText}" />
            </telerik:RadBorder>
            <Grid.GestureRecognizers>
                <TapGestureRecognizer Command="{Binding SearchMoreCommand}" />
            </Grid.GestureRecognizers>
        </Grid>
    </DataTemplate>
</telerik:RadListView.FooterTemplate>

1. TapGestureRecognizer: Command is not executed / Click not detected
2. Style: Having a PointerOver in "ListItemContainer" works with net7. Doesn't work with net8

Repro steps:

Put a grid inside a RadBusyIndicator with a button.  On a button click, set IsBusy to true, change the height of the grid, and set IsBusy to false.  The grid height will not be updated.

Another way to reproduce is to add children views to the grid while IsBusy is true.  The children will not be rendered after it's done

This is a regression from a recent Telerik update

Hi Team,

I have attached a reproducible. Open DashboardView.xaml, there you'll find the DataGrid.

Run the project on Windows and take the following steps:

• Step 1. Run the app and click Button 1 to load an instance of this ContentView
  
  • Observe => The DataGrid renders as expected
    
• Step 2. Click Button 1 again to reset and load a new instance of this ContentView
  
  • Observe => The DataGrid will NOT render (you can repeat this step multiple times)
• Step 3. Resize the app window
  • Observe the DataGrid will be rendered again

The only way I could get it to render again was by resizing the app window, even calling InvalidateMeasure(SizeChanged) didn't work.

The logic is simple, the button click just clears MainPage.xaml's container children and adds a new instance of DashboardView:

private void OnButton1Clicked(object sender, EventArgs e)
{
    currentContentViewHolder.Children.Clear();
    currentContentViewHolder.Children.Add(new DashboardView());
}

If I uncomment "HorizontalStackLayout", the image is not displayed.

I want to display 2 Imageeditor in the same tabview, how to do this ?

        <telerik:RadTabView 
            telerik:RadDockLayout.Dock="Left"
            x:Name="tabView" AutomationId="tabView"
            HeaderPosition="Bottom"
            >
            <telerik:TabViewItem HeaderText="Face 1">
                <!--<telerik:RadImageEditorToolbar ImageEditor="{x:Reference imageEditor}">
                    </telerik:RadImageEditorToolbar>-->

                <!--<HorizontalStackLayout>-->
                    <telerik:RadImageEditor x:Name="imageEditor1" 
                        MinZoomLevel="0.1" 
                        MaxZoomLevel="20"
                        Source = "{Binding DisplayedPhoto, TargetNullValue={versares:ImageResource Images.palette.png}}"
                                       />

                    <!--<telerik:RadImageEditor x:Name="imageEditor2" 
                        MinZoomLevel="0.1" 
                        MaxZoomLevel="20"
                        Source = "{Binding DisplayedPhoto, TargetNullValue={versares:ImageResource Images.palette.png}}"
                                       />-->
                <!--</HorizontalStackLayout>-->

            </telerik:TabViewItem>
            <telerik:TabViewItem HeaderText="Face 2">
                <Label Margin="10" Text="This is the content of the Folder tab" />
            </telerik:TabViewItem>
        </telerik:RadTabView>

I would like a control to handle Currency that works with the UICulture

In the US it would show the input as $ ____.00. or ____.00 (USD) based on UICulture

in other countries it would show the currency symbol based on the UICulture

This control should work will all other controls such as grid column input

I don't have definitive proof on when it started but I did update my Telerik.UI.for.Maui NuGet package from Trial to an official licensed version and that is when I started to see bizarre behavior for the ButtonToolbarItem control. Suddenly, NO FONT ICONS show! Also, in my log file, I see this:

Unable to load font 'TelerikFont'.

I don't have this font installed in my Maui Resources\Fonts folder nor do I load it in my MauiProgram ConfigureFonts extension method for the MauiApp builder. It was working until two days ago.

I turned on BLAST mode in my debugger where I was seeing exceptions being thrown all over the place with regard to loading fonts. I am up against a crucial investor funding demo so I do not have the time to dig down to the core of this issue at the moment. This issue I am logging is there for you to ask me questions on things I can verify so we can work on this together.

What are some of the things you need me to do or look at to report back... The fact that NONE of my FontImageSource icons are being displayed in my RadToolBar ButtonToolbarItems is suspect. The reporting of the TelerikFont is even more suspect. I wasted a TON of valuable time today trying to find a workaround, but none could be found. GitHub Copilot and ChatGPT kept giving me bogus answers for properties on your controls that don't exist which only exacerbated my frustration. I tried to use PNG files as the icon, but your ButtonToolbarItem image source only allows font image sources which I think is a very bad design decision on your behalf. What if a font does not provide the correct image I wish to display? You really should allow png images to be used on these buttons!!!

Like I said, it was working up until several days ago...

Thanks, Steve

Hi Team,

We have a need for being able to dynamically choose a template for the three available DataTemplate:

Thank you,
