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

Hello,

 

I'm using an horizontal listview, it's working well. But when I put in in a RadDocklayout, nothing is displayed. What am I doing wrong ?

 

See attached project.

 

Other question : is it possible to have cell fitting to the text inside the listview (ItemLength="*") ?

 

Regards

I have three RadDataForms in my login workflow. I have tried all of the various CommitModes and ValidationModes to prevent this error, but nothing seems to prevent these errors from manifesting.

I have a data form that has two fields: Username and Password. When this form is FIRST displayed, what appears to be validation errors (formatted error log output):

Then, I have a different RadData form that has five fields, First Name, Second Name, Email Address, Password and Password Confirmation. This leads to:

These errors are all encountered on the form's first load. Nothing has been entered into any field. No call to any validation methods is made. 

Here is how my general data form configuration is done:


<telerik:RadDataForm
    x:FieldModifier="public"
    x:Name="SignUpForm"
    Grid.Row="0"
    CommitMode="Explicit"
    Loaded="SignUpFormOnLoaded"
    Margin="0,5,0,0"
    Style="{StaticResource DataFormStyle}"
    ValidationMode="Explicit">

I have attached the three classes I use as the binding context. I have tried None, Explicit, and LostFocus as settings for the two modes and it has no effect. While these errors look harmless and the form does provide error-checked data upon validation, I simply hate having any unnecessary errors in my log files.

What can I do to prevent these errors?

Thanks!

Steve

I tried to make an horizontal listview, using ListViewGridLayout. I want only one row with all the items from the collection.

I don't know how to set the SpanCount properly.

In the template, the image is not displayed (the function ImageResource  is working in other control), only the Label is displayed.

                <telerik:RadListView 
                    Grid.Column="3"                
                    ItemsSource="{Binding StepList}"

                    <telerik:RadListView.ItemTemplate>
                        <DataTemplate>
                            <telerik:ListViewTemplateCell>
                                <telerik:ListViewTemplateCell.View>
                                        <Grid>
                                            <HorizontalStackLayout Margin="10, 10, 10, 0">
                                                <Image IsVisible="True"  Source="{versares:ImageResource Images.nextstep.jpg}" HeightRequest="16" VerticalOptions="Center" />
                                                <Label Text="{Binding DisplayedName}" FontSize="16" FontAttributes="Bold" TextColor="Black" VerticalOptions="Center" />
                                            </HorizontalStackLayout>
                                        </Grid>
                                </telerik:ListViewTemplateCell.View>

This is a useful control from UI for WPF, maybe it could make the jump to MAUI?

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>

What is the best way to load a byte[] (which is a jpeg file) in the ImageEditor.

Ideally I want to transform the byte[] to a Bitmap (easy), for storage purpose

            using Stream stream = new MemoryStream(e.Buffer);
            using Bitmap image = new Bitmap(stream);

And then display the bitmap, but I don't know how totransform it to an ImageSource.

Regards.

Is it possible to use GestureRecognizers in ImageEditor ? I tried this, but OnImageTapped is not called.

             x:Class="PalletGate.Views.SingleEditor">

        <telerik:RadImageEditor x:Name="imageEditor1" 
                        MinZoomLevel="0.1" 
                        MaxZoomLevel="20"
                        Grid.Column="0"
                        >
            <telerik:RadImageEditor.GestureRecognizers>
                <TapGestureRecognizer Tapped="OnImageTapped" />
            </telerik:RadImageEditor.GestureRecognizers>
        </telerik:RadImageEditor>
    </Grid>
</ContentView>

Code behind :

    private void OnImageTapped(object sender, TappedEventArgs e) {
        Point? position = e.GetPosition((Element)sender);

         Telerik.Maui.Controls.RadImageEditor? img = sender as Telerik.Maui.Controls.RadImageEditor;
    }

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.

I'm getting a NullReferenceException when trying to display a RadDataGrid that has a column where one of the objects in the PropertyName "chain" is null. For example, in your Columns -> Columns Overview section of your sample SDK browser (SDKBrowserMaui.Examples.DataGridControl.ColumnsCategory.ColumnsExample.Columns.xaml) the data grid is bound to a list of Clubs. If you add this code to Club (With nothing else. Keep Manager null):

private Person _manager;
public Person Manager
{
    get { return _manager; }
    set { UpdateValue(ref _manager, value); }
}

and then add this column to the grid:

<telerik:DataGridTextColumn PropertyName="Manager.Name" 
                            HeaderText="Manager"/>
When you run the application and get to that grid, you'll see one of 2 things. Either the grid throws a null reference exception or it looks something like this:

Hello,

TL;DR version - I request that the IFontElement interface (from Microsoft.Maui.Controls.Internals) be implemented on all Rad type controls that display text.

Detailed Version:

The CommunityToolkit.Maui.Markup nuget package provides some really nice extension methods that allow quick and easy configuring of controls without verbosity. When using the toolkit along side Telerik UI every extension I have tried works really well except for .Font(). On all standard MAUI controls you can just call the .Font() extension method and don't need to create a Style and apply it to an underlying property just to set a font size - you just set the size with .Font() as shown below. The below example code snippet shows the normal use of the toolkit on a standard MAUI Label and a RadTimeSpanPicker from the Telerik UI MAUI package.

The above example yields the following error, as does calling .Font() on pretty much every other Radxxxx control. Telerik UI controls seem to work really well with all the other extension methods I have tried from the toolkit except the .Font() extension method.

The type 'Telerik.Maui.Controls.RadTimeSpanPicker' cannot be used as type parameter 'TFontElement' in the generic type or method 'ElementExtensions.Font<TFontElement>(TFontElement, string?, double?, bool?, bool?)'. There is no implicit reference conversion from 'Telerik.Maui.Controls.RadTimeSpanPicker' to 'Microsoft.Maui.Controls.Internals.IFontElement'.

It would seem that implementing IFontElement would solve this.

This would be a nice feature and very helpful to anybody using the toolkit with Telerik controls because they could be used the same way as standard MAUI controls.

I looked under the hood a little bit and I believe the interface could/should be implemented on something like RadContentView which seems to be where most interfaces are inherited/implemented, and controls like RadTimePicker inherit from parent controls that eventually inherit from RadContentView.

When focusing on combobox either by clicking on combobox or through tab focus it open the dropdown but many time it happens that the dropdown keeps blinking which makes it impossible to select any item from the dropdown. And due to very rapid show and hide of the dropdown it does not let choose any other control on the page and makes the entire page unusable.

I have been trying to get the DataGrid to work with Maui.Markup and I'm not finding a way to add a DataGrid to my View.

i.e. from GitHub - CommunityToolkit/Maui.Markup: The .NET MAUI Markup Community Toolkit is a community-created library that contains Fluent C# Extension Methods to easily create your User Interface in C#

I would have expected I could add a DataGrid to the Children of Grid...but I'm not finding the right cast to allow that to happen, Grid.Children is expecting an IView.

Is this possible and I'm just missing something simple?  Thanks!
