SfRichTextBoxAdv ImageBrush binding error

I get the following binding error coming from the SfRichTextBoxAdv:


Error 1 null ImageSource ImageBrush.ImageSource ImageSource Cannot find governing FrameworkElement or FrameworkContentElement for target element.

The problem comes from the "SuggestionBox", If I'm using an older version that v18.4.0.30 (Here the SuggestionBox was implemented) I don't get the error.

<local:SfRichTextBoxAdvExtension

    x:Name="richTextBoxAdv"

    Grid.Row="1"

    EnableMiniToolBar="False"

    LayoutType="Continuous"

    Style="{StaticResource DefaultRichBoxStyle}"

    HtmlText="{Binding Path=DataContext.MessageBody, RelativeSource={RelativeSource AncestorType=sirius:DialogView}, Mode=TwoWay}"/>

The style is not important, it also appears without it.

Avrigeanu, based on the provided code snippet, we can confirm that you are using the SfRichTextBoxAdvExtension and HtmlText property. However, you have mentioned two issues where the applied style is not preserved, and a binding error is encountered. With the provided details, we cannot reproduce both issues.

We have attached a sample application with SfRichTextBoxAdvExtension. Please modify the shared sample to reproduce both issues so that we can validate and update you with further details as soon as possible.

Avrigeanu, as promised earlier, we have included the fix for the reported bug with “ImageBrush binding error is shown in the SfRichTextBoxAdv” in our latest weekly NuGet release (v25.1.37).

Root cause of the issue:

We have provided support for the auto-suggestion functionality, where we can set the Name, link, and image for the auto-suggestion. We have a default template in the code-behind designed to be shown in the UI when performing the auto-suggestion.

This default template is initialized when the SfRichTextBoxAdv is initialized. The template includes an ImageBrush control with its Image Source property bound, which is initially null. If the SfRichTextBoxAdv is launched without the auto-suggestion functionality, a binding error is shown.

Please use the below link to download our latest weekly NuGet:
https://www.nuget.org/packages/Syncfusion.SfRichTextBoxAdv.WPF/25.1.37
