HTMLDataProvider won't render images in RadRichTextBox

Having an issue displaying images in a radRichTextBox. Below is my HTML.

I have using an HTMLDataProvider to bind to a string that contains this HTML below.

The image does not display, all I get is this little box for the image.

The text all displays fine above it.

<head>
<link rel="stylesheet" href="../style.css" /> 
</head>
<p><strong>Section Header</strong></p>

<p><strong>Section Text</strong> This is my Description section</p>

<p><strong>Picture Title</strong></p>
<p><img src="../LocalFolderParent/Images/MyImage.png" alt="Figure 1 - Test 3" /></p>

RadGridView Distinct Filters stopped working after release 2022.2.511

After installing release 2022.2.511, the distinct filters of our grid views stopped working. We are using popup filters in a custom class with both distinct checkboxes and field filters visible. Clicking on any distinct checkbox and then clicking Apply Filter button would always filter the grid, but after the 2022.2.511 release, clicking on distinct checkboxes and clicking Apply Filter now does nothing but close the filter popup with no effect to the results. However, if the EnableDistinctValuesFiltering property is set to true, and some text is typed in the distinct search text box, and then the checkbox is checked and Apply Filter is clicked, the filtering works.

Is there some breaking change that was made that we should know about when dealing with distinct filters in the custom popup? Is there any settings that we can try to help resolve this issue?

Thanks, Bob

RadGridView with main and child datasets

How is it possible to display main and secondary data records in a RadGridView not using the hierarchy options, but rather to design it in such a way that the main columns extend over the corresponding rows of the secondary data records via RowSpan, whereby both main and secondary data records have multiple columns?

RadButton

I created a new WPF project in Visual Studio 2022 - opened the XAML, dropped a RadButton. Nothing appeared. Where did it go? When I did the same steps in Visual Studio 2019 I see the button all right.

How to get Image inside RTB to always fill width

I have an RTB control and I do not want horizontal scroll bar to ever show. When a user inserts or copies in an image, I would like the image to always only ever fill the width of the RTB and never exceed it. Increasing height, is fine, vertical scrolling is acceptable in this instance.

Is this a possibility? I am able to do it with tables.

RadGridView LostFocus raised by mouse wheel

I have to react to the RadGridView's LostFocus event with a handler. Unfortunately, I discovered that the event is also triggered at unexpected times. What is particularly surprising is that scrolling with the scroll bar has no effect, but scrolling with the mouse wheel immediately calls the handler. And it does this without clicking the mouse and leaving the control. What could be the reason for this, or how can I get around it? The actual case that should be reacted to is when either another item of it is selected or the entire RadGridView loses focus by focusing on a control outside of it. Simply checking e.OriginalSource.GetType() == typeof(GridViewCell) doesn't help here either, as this is often the case when clicking on another control. And IsScrolling is also constantly false.Does anyone have any ideas?

Support for CommunityToolkit.Mvvm ObservableProperty in WPF PropertyGrid control

I created a class with CommunityToolkit.Mvvm package and use ObservableProperty to create properties for this class. But the PropertyGrid control does not recognize properties created in this way. Are there any way PropertyGrid can support ObservableProperty?

using CommunityToolkit.Mvvm.ComponentModel;
using System.ComponentModel.DataAnnotations;

namespace Test
{
    public partial class DrawingModel : ObservableObject
    {
        public string Name { get; set; }

        [ObservableProperty]
        public double _length;


        [ObservableProperty]
        public double _width;

        [ObservableProperty]
        public double _height;
    }
}

Creating a RadDocument from XAML string

I have a XAMLDataProvider that is binding a string property to a RadRichTextBox.

I want to be able to bind the content of the RadRichTextBox to a string (which I have done) and then once a save button is pressed, I need to run some code similar to this.

Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider provider = new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
RadDocument document = new RadDocument(string myXAMLString);
byte[] output = provider.Export(document);

Essentially I need to be able to bind a property from the ViewModel to RadRichTextBox..... which I am doing with XAML data provider.

Then after a save button is clicked, I take the property which is a string and I need to create a RadDocument from the string that represents that and export that document to a byte[].

Is there an easier and better way to be doing this?

Thanks!
