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. 

We have discovered an error when you implement IWindowCreator and create custom window and connect viewmodel via AddSingleton approach

This is the stack-trace:

Hi,

Please look  WPF EntityFrameworkCoreDataSource - Overview - Telerik UI for WPF

Hi,

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

Add gRPC as an alternative to WCF.

Thanks,

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 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 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

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.

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>

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.

The stack trace is strange:

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

Best regards,

Marcel Souza
