I just made a little test application using the .NET 6 Preview 6 and MAUI with chart control to see if we can use it for a future project. I was able to display just a basic chart with 1000 points in it, in ascending order on X axis. But the performance is really not there when running on my Android 10 device. I only made a Zoom at factor 2 and use panning right to left and it's not smooth at all. There is nothing in the chart (no grid, no annotations). Just a simple 2 axis chart. I can really not go with this because there will be many more data in our product at the chart need to be fast enough. Maybe it's a settings somewhere that need to be adjusted... Take a note that I was able to run the chart in WinUI project and the performance is correct, but I am on a very fast PC, it is just normal to be fast. Note: There is some kind of deceleration effect when panning, I want to disable it but not found how.

Anyway, it will be really cool if you can provide a very simple MAUI test application with the fastest full screen chart with Pan/Zoom with 1000 points (which for me is really not much data) and the corresponding code to me to validate if your library can do the job. I know that MAUI and .NET 6 is not released yet, but performance should be there now because it's really close to bug fixing only state now. Thanks.

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:

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'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 ? 

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.

Hi Team,

This is specifically a feature request to add a new control, or Window extension, that allows desktop developers to show a splashscreen window on the target desktop platform.

We understand this is not possible on mobile targets, but it would be nice to have for desktop,

For inspiration, see the Telerik UI for WPF RadSplashScreen control => WPF SplashScreen | Overview | Telerik UI for WPF

The Bottom Sheet component provides an intuitive way to display additional content to the users. It appears on the bottom of a screen as an overlay and presents users with a choice of actions that they must take.

Currently the SuggestionView does not stay open all the time

I can get it to open on focus by running this code and attaching it to the Focused event

    Focused += SupporterAutoCompleteSearchBar_Focused;

    private void SupporterAutoCompleteSearchBar_Focused(object sender, FocusEventArgs e)
    {
        ShowSuggestions();
    }

Hello,

it would be a very useful information when subscribing to the DataBindingComplete Command of a DataGrid to know whether for example a filter, sort, grouping had changed.

Currently, it is an internal Property

Regards
