xamarin-demos's Issues

Missing Init Code in samples

All the samples make a call to an init function that as near as I can tell is not provided in source code form.

On Android, the implementation of every MainActivity::OnCreate has the following line:

SampleBrowser.Core.Droid.CoreSampleBrowser.Init(Resources, null);

On iOS, the implementation of every AppDelegate::FinishedLaunching has the following line:

SampleBrowser.Core.iOS.CoreSampleBrowser.Init(UIScreen.MainScreen.Bounds, app.StatusBarFrame.Size.Height);

As near as I can figure this code lives in the SampleBrowser.Core.16.3.0.21.nupkg nuget package and is where the magic sauce is that keeps the controls from being rendered under the notification area up at the top on iOS and who know what other magic. I assume we should not ship the SampleBrowser.Core package as part of our syncFusion apps, so is there any other way we can see what is happening in this init function?

sfimageeditor not support mvvm I

sfimageeditor not support mvvm as ImageSaving and ImageSaved events not bindable

SfPdfViewer change orientation

when pdf viewer change orientation, the view will turn to white and if i change it back it will not respond and will give me this on my output:

Latest SfRotator (v18.4.0.49) raises exception on UWP:
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: index
at System.Runtime.InteropServices.WindowsRuntime.VectorToListAdapter.GetAt[T](IVector`1 _this, UInt32 index)

while previous versions ( <= v18.4.0.48) runs normally.

SampleBrowser.SfPdfViewer does not start in UWP

I simply download and extract the whole of the SampleBrowser.
Rename the folder because it causes a path length issue.
Open in Visual Studio 2022 current version.
Wait for a few moments until the pointer stops spinning.
Select X64, SampleBrowser.SfPdfViewer.UWP, Local Machine.
Run it.

I get the following error:

Exception thrown: 'System.TypeLoadException' in SampleBrowser.SfPdfViewer.UWP.exe An exception of type 'System.TypeLoadException' occurred in SampleBrowser.SfPdfViewer.UWP.exe but was not handled in user code Could not find Windows Runtime type 'Windows.UI.Xaml.Markup.IXamlType2'.

Thanks for looking at this.

[Bug] SfListView have compatibility issue with Xamarin.Forms 4.7.0.937pre4 and above (4.7.0.968 the Stable Release) on UWP

Starting from Xamarin.Forms 4.7.0.937-pre4 and Stable Release(4.7.0.968) , the latest version of SfListView behaves abnormally on UWP:

The tap event of an item in SfListView get called in mislocation or never get called (caused by malposition). For example, when the 8th row is tapped actually, the 2nd row or a button in the UI get called its own tapped event. Weird.

Since the issue still exists when compiled with Xamarin.Forms 4.7.0 Stable Release, this feedback is provided to help figure out the cause.
Thanks a lot. Have a good day.

Setting icon on the top row

Hi, I would like to reuse the code behind RecursiveAppointments.xaml and its view model.

Is that ok to use it in my App? Just wanted to be sure of the license on usage of this code.

I also see that SampleBrowser.SfSchedule.props file has a itemgroup that refers to RecurrenceAppointments.xaml / .cs and its , View Model.
Is there a documentation that explains the intent to use this view in this manner via MSBuild steps / props file?

Thanks

Button's click event in the DropDownFooter of SfAutoComplete not get called

As the documentation suggests, the footer could be designed to respond to the user's "Add New" action. (https://help.syncfusion.com/xamarin/autocomplete/header-and-footer)

However, if we put a Button in the footer, the Click event of the button don't get called when the footer is tapped. Are there any further configurations needed to be set to get it work? Many thanks.

[Bug] SfChipGroup, SfStepProgressBar, SfAvatarView, SfRichTextEditor causes InvalidURI exception with Xamarin.Forms 5.0.0 on UWP

With Xamarin.Forms 5.0.0, the Xamarin team made an intentional modification which make existing Syncfusion Controls raise InvalidURI Exception when Custom Font is specified.
Please check the link.
As the post pointed out, SfRichTextEditor causes such URI format exception.
I find that SfStepProgressBar and SfAvatarView also causes the Exception, for StepView.PrimaryFormattedText is specified with FormattedString.
I guess more Syncfusion controls would be affected so I posted this to let you know.
Have a nice day.

Controls don't adopt Dark Theme automatically like those native controls

Syncfusion controls are awesome. Here I encounter a little problem when trying to support dark mode.

When setting the XAML of Xamarin.Forms projects to Dark Theme, the native controls will be dark, but some Syncfusion control doesn't automatically adopt the Dark Theme. Instead, each control (e.g., AutoComplete, DataGrid, etc.) needed to be configured with specified attirbutes like BackgroundColor, TextColor and so on, in order to provide the user with a proper Dark Theme.

Are there any ways to make all the Syncfusion control go with the theme configuration automatically, just like those native controls? Thanks a lot.

SfPdfViewer cannot open HyperLinks when targeting Android SDK 33

New apps on Google Play must target Android 13 (API level 33) [1]

Setting the target SDK to 33 defined in /Android/SampleBrowser/Properties/AndroidManifest.xml

+       <uses-sdk android:minSdkVersion="21" android:targetSdkVersion="33" />
        <application android:label="Syncfusion Components for Xamarin.Android" android:largeHeap="true">

Is done as shown above, however, Android is no longer able to open any Hyperlinks in the PDFViewer example.

Android PDFViewer screenshot

It still shows the dialog just fine, but choosing Open only closes the dialog without opening the web browser. How do I allow the user to open hyperlinks?

[Bug] Doc to PDF conversion Character Overlap on Android (Font Substitution not working)

When converting doc to pdf, if the document contains character-based content and numeral/symbols, the font substitution does not working as expected, causing overlapping in pdf file.

On UWP, FontName of CharacterFormat can be specified to use a pre-installed Microsoft YaHei or Arial Unicode MS as a workaround. However, Font Substitution doesn't work.
On Android, either specifying FontName to Droid Sans Fallback or using Font Substitution doesn't work.

Thanks a lot.

Environment:
Windows 10 Build 20246
Visual Studio 2019 16.8.3
Xamarin 5.0.0
Syncfusion 18.3.0.53
Android 10

Code Snippet to reproduce the issue:

void OnButtonClicked(object sender, EventArgs args)
{
WordDocument document = new WordDocument();
WSection section = document.AddSection() as WSection;
IWParagraph paragraph = section.AddParagraph();
WTextRange textRange = paragraph.AppendText("第5天，日期2020年12月9日") as WTextRange;
//textRange.CharacterFormat.FontName = "Microsoft YaHei"; //"Arial Unicode MS"; // Specifying FontName WORKS on UWP
document.FontSettings.SubstituteFont += FontSettings_SubstituteFont; // Font Substitution NOT WORK
DocIORenderer render = new DocIORenderer();
PdfDocument pdfDocument = render.ConvertToPDF(document);
document.FontSettings.SubstituteFont -= FontSettings_SubstituteFont;
render.Dispose();
document.Dispose();
MemoryStream outputStream = new MemoryStream();
pdfDocument.Save(outputStream);
pdfDocument.Close();
Xamarin.Forms.DependencyService.Get().SaveAndView("CharOverlapWithNumerals.pdf", "application/pdf", outputStream);
}

void FontSettings_SubstituteFont(object sender, SubstituteFontEventArgs args)
{
if (args.OriginalFontName == "Arial Unicode MS")
args.AlternateFontName = "Droid Sans Fallback"; //"Microsoft YaHei";
else
args.AlternateFontName = "Times New Roman";
}

Converting Doc to Pdf causes non-ASCII numeral/symbols to overlap with characters in the same paragraph

Syncfusion documentation provides detailed steps to generate doc in code and convert it to pdf using DocIORenderer. 
**It works perfectly when the doc contains only ASCII characters. However, when character-based language (e.g., Chinese, Japanese, etc.) is in the paragraph, the numbers (0~9) and symbols (e.g., _  /  ~, etc)  overlap with other characters in the same paragraph in the converted PDF.**
The doc file looks perfect. The bug happens when converting it to PDF.

Simple demo to reproduce the bug:

1. Init a doc instance. WordDocument doc = new WordDocument();
2. Add a section. WSection sec = doc.AddSection() as WSection;
3. Create a paragraph. IWParagraph p = sec.HeadersFooters.Header.AddParagraph();
4. Add the paragraph with some character-based language content and numerals/symbols. p = sec.AddParagraph(); p.AppendText("现在是第5天，日期2020年5月16日");
5. Save doc to memory stream. MemoryStream stream = new MemoryStream();
   doc.Save(stream, FormatType.Docx);
6. Convert doc to PDF. DocIORenderer render = new DocIORenderer();
   PdfDocument pdf = render.ConvertToPDF(doc);
   render.Dispose();
   doc.Dispose();
   MemoryStream pdfStream = new MemoryStream();
   pdf.Save(pdfStream);
   pdf.Close();
   DependencyService.Get().PrintStream(pdfStream, "Character-based_PDF_Convertion.pdf");

The overlapped output pdf snip image is as follows:

How to show organization chart in vertical Layout.?

I am trying to use Org structure but the problem is if you have a number of nodes then is it is expanding horizontally. Can we show 5-6 nodes in one line? and rest node in the next line.

I have one more question. Can we bind data in XAML itself instead of code behind.?

STOP ADVERTISING ON VISUAL STUDIO

You are corrupt. You are exploiting the search system in the Visual Studio Extensions and Updates window to advertise these crap products.

Searching for "react", for example, in Visual Studio, gives you 3 pages full of these garbage, polluting the results on purpose.
