Regardless of the RadEntry's BackgroundColor property, I've noticed the visible-background-color to differ when the RadEntry receives active focus.

The observed behavior is this:

  • RadEntry's visible-background-color generally equals RadEntry's BackgroundColor property
  • RadEntry's visible-background-color changes to gray when hovered regardless of day-night mode
  • RadEntry's visible-background-color changes to white when focused
  • RadEntry's visible-background-color restores to RadEntry's BackgroundColor when unfocused

Typically, in day mode settings (Windows default), the RadEntry's BackgroundColor == white so you don't see the problem. However, in night mode settings (Android default), we want the RadEntry's BackgroundColor == black so the problem is more prevalent since you're typing white text on a white background.

When using Visual States, and, if you try to re-enforce the same BackgroundColor property in all of the visual states, sometimes focus, hover, unfocus, hover, focus sequence will allow you to edit in the RadEntry in your desired RadEntry's BackgroundColor property instead of white, but, most of the time is white.

This problem can be reproduced on Windows and Android if you set your application to night mode Application.Current.UserAppTheme = AppTheme.Dark and set RadEntry's BackgroundColor=Black and TextColor=White in XAML. Put 2 or 3 RadEntry's on the page so you can navigate between them to see the problem.

A control that would read a QR code and return a string would make me buy this. I am currently using an ASP.NET Telerik Forms Site with instascan.js to read a QR code using a mobile camera, call an API endpoint, and display an alert (the heavy lifting is done on the server in the API). A simple QR scanner would be really useful in a mobile app "out of the box" unless you can suggest a free/low cost component I can plug into a solution based on the new MAUI platform from Telerik?

Hello,

there is probably a Bug in the ListPicker Commands. (https://docs.telerik.com/devtools/maui/controls/listpicker/commands)

Like in the example:

  private void OnAccept(object obj)
    {
        // implement your custom logic here
    }

the object is null. 

Shouldn't you get the selected value for further implementations?

When programatically trying to add an item to RadComboBox.SelectedItems (in multiple selection mode) similar to this answer, we get an ArgumentOutOfRangeException on iOS.  It works fine on Android.

https://www.telerik.com/forums/radcombobox-binding-selecteditem-not-work-when-selectionmode-is-multiple

The stack trace is strange:

Currently Telerik MAUI controls doesn't seem to support Light and Dark Themes(Modes). It will be really helpful to have this feature built in the controls or through styles supported by those controls so that these controls blend in nicely with the Light and Dark Themes supported by the app.

I tested Android and iOS only. Other platforms i cannot test at the moment.

 

Given the following implementation of the Combobox i observ different behaviour if the bound item is a enum or a class.

<telerik:RadComboBox x:Name="a"
                     ItemsSource="{Binding CloudProviders}"
                     SelectedItem="{Binding SelectedCloudProvider}"
                     IsClearButtonVisible="False">
    <telerik:RadComboBox.ItemTemplate>
        <DataTemplate>
            <Grid HeightRequest="40"
                  Padding="10">
                <Label Text="{Binding Title}"
                       TextColor="{DynamicResource DisabledTextColor}"
                       FontSize="14" />
            </Grid>
        </DataTemplate>
    </telerik:RadComboBox.ItemTemplate>
    <telerik:RadComboBox.SelectedItemTemplate>
        <DataTemplate>
            <Grid HeightRequest="40"
                  Padding="10">
                <Label Text="{Binding Title}"
                       TextColor="{DynamicResource DisabledTextColor}"
                       FontSize="14" />
            </Grid>
        </DataTemplate>
    </telerik:RadComboBox.SelectedItemTemplate>
</telerik:RadComboBox>

 

If the Itemssource is a Array of a enum type it works as intended.

If the Itemssource is a Array of classes the initial selected display member is not visible. The moment i tap into the closed combobox, the selected member is visible.

 

The attached screenshots show the page after loading and after touching into the white area(combobox) once.

 

For Localization and more details, we want to use classes. Is this a bug or do we have a issue in our code here?

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'm looking for a splitter control (to display master info on the left view and detailed info on the right view, and the possibility to resize both view)

i tried : Add Splitter control (telerik.com) but it's not working well (only moving a little bit, then it stops)

Any idea how to achieve this ?

I'm looking for a control for .net maui for cross-platform desktop development that lets you resize the different sections of your user interface like the GridSplitter control does in WinUI.

Please see attached image - the symbols of the toolbar items are not displayed properly.
Note this only happens in a WinUI unpackaged app - <WindowsPackageType>None</WindowsPackageType>.
 
This seems to be an MS issue, which is logged here (https://github.com/dotnet/maui/issues/19608).
 
One possible work-around is to manually set the ImageSource property for each item in the toolbar. Then for example images can be used in the source, or glyphs from some built-in font may be used (like Arial, Calibri, Segoe UI).

I would like to see a new feature in the RadComboBox for "Select All" functionality.

Here is the general functional paradigm I'm hoping to see.

1. All Selection

  • If user checks Select All, it should display every item in the list as checked
  • If user unselected All then every item should be unchecked.

2. Partial Deselection

  • If user unselect only one item, then it should only unselect that item, but also uncheck the "Select All" checkbox, while leaving the reaming items still checked.

Although Maui has SpreadProcessing, it lacks a matching control. For the very different WPF platform you have one I use, and it would be helpful in Maui to display and readily edit class instances with numerous properties. I realize it would be a challenge to fit into mobile screens, but I do hope you will consider it, as I am trying to get all my current WPF features into my Maui work-alike. Thank you.
