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.

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. 

Hi,

Similar to WPF:   WPF DataServiceDataSource - Overview - Telerik UI for WPF

Add gRPC as an alternative to WCF.

Thanks,

Hi,

Please look  WPF EntityFrameworkCoreDataSource - Overview - Telerik UI for WPF

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:

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

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 ?

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 ? 

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.

In certain situations, the RadTabView cuts off part of the header text for some of the headers.  A specific scenario where this is happening is when the following tabs are present: 

• General
• Feed
• Users (0)
• Relationships (0)
• Tickets (0)
• Attachments (0)

The problem is worse when the BorderThickness of the TabViewHeaderItem is set to 1

  <Grid>
    <telerik:RadTabView>
      
      <telerik:RadTabView.HeaderItemStyle>
        <Style TargetType="telerik:TabViewHeaderItem">
          <Setter Property="BorderColor"
                  Value="Black" />
          <Setter Property="BorderThickness"
                  Value="1" />
        </Style>
      </telerik:RadTabView.HeaderItemStyle>
      
      <telerik:TabViewItem HeaderText="General" />
      <telerik:TabViewItem HeaderText="Feed" />
      <telerik:TabViewItem HeaderText="Users (0)" />
      <telerik:TabViewItem HeaderText="Relationships (0)" />
      <telerik:TabViewItem HeaderText="Tickets (0)" />
      <telerik:TabViewItem HeaderText="Attachments (0)" />
      
    </telerik:RadTabView>
  </Grid>

Steps to reproduce:

Run the SDKBrowser example from the Telerik UI for .NET MAUI 6.1.0 package following this instruction: https://www.telerik.com/blogs/running-ios-simulator-windows-net-maui

Using Telerik UI for .Net MAUI v1.0.1 with latest version MAUI 6.0.400 (Service Release 1) and Visual Studio 2022 17.3.0 Preview 2.0 generates an error,

Severity Code Description Project File Line Suppression State
Error PRI175: 0x80073b0f - Processing Resources failed with error: Duplicate Entry. MauiAppTest C:\Samples\MauiAppTest\MauiAppTest\WINAPPSDKGENERATEPROJECTPRIFILE 1

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

I would love to have an option to display a calendar in the DatePicker date selection popup
