    I’ve found that when there is an RTF control on a section report, and attempt to render this through a .net core project, it does not render (it’s blank).

    Looking at some doc, it seems that there is a switch that should be used for that on the section report:

    this.CompatibilityMode = GrapeCity.ActiveReports.Document.CompatibilityModes.CrossPlatform;

    vs

    this.CompatibilityMode = GrapeCity.ActiveReports.Document.CompatibilityModes.GDI;

    When using the CrossPlatform, whether it is in a Framework project or core project, the RTF controls do not render. This can be demonstrated by using the example provided in this other post, and inserting that CrossPlatform line in the designer:

    FYI – I am using AR 16.1.2, VS2022, .Net Core 6.0 and a framework project to do preview support in framework 4.7.2.

    Is there a workaround for this, or is this something that has been discovered?

    Thanks!

    Hi Todd,

    This is a known limitation in ActiveReports 16, when using CrossPlatform CompatabilityMode the RichTextBox renders only HTML content. Thus specifying RTF content to RichTextBox at runtime previews nothing, to learn more about the same please refer to RichTextBox https://www.grapecity.com/activereportsnet/docs/versions/v16/online/rich-textbox.html.

    However, specifying plain text or loading your RTF file through the designer converts them to HTML when loading into the RichTextBox control.

    As a workaround in CrossPlatform Compatability please add your RTF content between the body tags and assign it to the Html property of your RichTextBox. Please refer to the following line of code:

    richTextBox1.Html = "<html><body>mytext</body></html>";

    Please find attached a sample implementing the same.

    Apologies for the inconvenience.

    Regards,

    Anand

    Thanks Anand, I missed that part of the docs.

    I’m able to get them to show up if I convert to html.
