WPF Syntax Editor Intelliprompt Background is Transparent?

SyntaxEditor for WPF Forum

I'm a beginner working with intelliprompt that's using a custom schema. The intelliprompt suggestions load fine, but the window background for intelliprompt is transparent instead of opaque. Any idea why this would be happening? I haven't changed any default styling that I know of.

We haven't seen that happening.  Can you make a new simple sample project that shows it happening and email that to our support address, referencing this thread?  Then we can have a look to see what's going on.  Please exclude the bin/obj folder so it doesn't get spam blocked.  Thanks!

Hi, I had the same issue, the solution I found was to overwrite the styling on the intellipromt completion list. if you add this to your resource dictionary for the window containing the editor it should sort the issue:

<Style TargetType="editor:IntelliPromptCompletionList">
    <Setter Property="Background">
            <SolidColorBrush Color="White" Opacity="1"/>
    <Setter Property="BorderBrush" Value="#FFC2C4C7"/>

The other customer was loading SyntaxEditor in interop (an Excel add-in) and not running a WPF .exe.  In that scenario, no WPF Application was created by default, so theming couldn't apply.

Are you using SyntaxEditor in an interop scenario?

If so, take a look at this documentation topic in the "Using WPF Controls in Windows Forms Applications" section.  The same information applies to any interop scenario, Windows Forms or other ones like Office add-ins.  If you create the WPF Application before your main Window loads, it resolves the issue without any workarounds needed.  Make sure you shut down the Application too when your main Window is closed.
