Cannot implement Search on Viewer

As your samples, pdfviewer and pdfviewer renderer classes created. open pdf file in a control works fine. but can not add search button on view and can not search text. tried many ways to show but nothing changed.

I will need a little more information to assist you. Can you tell me which SDK package you are using, Xamarin.Android or Xamarin .iOS, and the PDFNet SDK version number you are working with.

PDFTron.iOS and PDFTron .iOS.Tools (Xamarin.iOS Nuget Package) both versions 10.3.0. not sure about PDFNet but PDFNetiOS.dll version is 0.0.0.0 (from debug folder).

var textSearchViewController = new PTTextSearchViewController(mPdfViewCtrl);
textSearchViewController.SearchViewControllerDidDismiss += (sender, e) =>
{

        };
        var navigationController = new UINavigationController(textSearchViewController);

        navigationController.ModalPresentationStyle = UIModalPresentationStyle.Popover;
        navigationController.PopoverPresentationController.BarButtonItem = searchButton;

        UIWindow window = UIApplication.SharedApplication.KeyWindow;
        UIViewController vc = window.RootViewController;

        while (vc.PresentedViewController != null)
            vc = vc.PresentedViewController;

        vc.PresentViewController(navigationController, true, null);

        NativeView.AddSubview(mPdfViewCtrl);

        NSLayoutConstraint.ActivateConstraints(new NSLayoutConstraint[]
        {
            documentController.View.LeadingAnchor.ConstraintEqualTo(this.NativeView.LeadingAnchor),
            documentController.View.WidthAnchor.ConstraintEqualTo(this.NativeView.WidthAnchor),
            documentController.View.BottomAnchor.ConstraintEqualTo(this.NativeView.BottomAnchor)
        });

        NSLayoutConstraint.ActivateConstraints(new NSLayoutConstraint[]
        {
            mSearchView.View.LeadingAnchor.ConstraintEqualTo(this.NativeView.LeadingAnchor),
            mSearchView.View.WidthAnchor.ConstraintEqualTo(this.NativeView.WidthAnchor),
            mSearchView.View.BottomAnchor.ConstraintEqualTo(this.NativeView.TopAnchor)
        });

above code added in SetupUserInterface() function. I want to show like your PTDocumentController document 7.Text Search button. this code shows popup from left up corner but this time pdf can not be viewed.

Hi @busranerse,

Are you able to share some more information about the exact issue you’re seeing?
Could you share a video showing the problem as well as a description of the expected behaviour?
