The ActiveFilter property is intended to capture input from users. When a user selects a filter through the UI, the search functionality can then operate based on that selection.

However, if it is necessary to modify this property programmatically, here is an example of how to do so:

[Action(nameof(DevTestAction), Name = "Change active filter")]
[ActionLayout(typeof(DevTest), 10, DisplayType.Large)]
public class DevTestAction : AbstractAction
{
    protected override void Execute()
    {
        var projectController = SdlTradosStudio.Application?.GetController<ProjectsController>();
        var fileBasedProject = projectController.SelectedProjects.First();

        var tbSettings = fileBasedProject.GetTermbaseConfiguration();
        tbSettings.Termbases.First(tb => tb.Name == "termbaseName").FilterName = "filterName";

        var path = GetPathFromTermbaseSettingsXml(tbSettings.Termbases.First().SettingsXML);
        tbSettings.TermbaseServerUri = new Uri(path);

        fileBasedProject.UpdateTermbaseConfiguration(tbSettings);
    }

    public static string GetPathFromTermbaseSettingsXml(string xml)
    {
        var doc = XDocument.Parse(xml);
        var pathElement = doc.Descendants("Path").FirstOrDefault();
        return pathElement?.Value;
    }
}

There is a bug in Studio that prevents updating the termbase configuration settings unless a TermbaseServerUri is first provided. For file-based terminology providers, this corresponds to the path of the terminology file. This requirement is why the additional call to the GetPathFromTermbaseSettingsXml method is necessary. An item will be created for the Studio team to address this issue so that, in the future, the settings can be updated more easily.

If this does not resolve the issue, please provide additional details about your scenario so we can offer a more targeted solution.

Thanks, that looks promising. I'll give it a go when I'm back from my holidays
