I am new to Xamarine.
I had created new blank Xamarine project in Visual studio 2019.
I am using this link to create demo native views in Xamarine forms : https://learn.microsoft.com/en-us/xamarin/xamarin-forms/platform/native-views/xaml
MainPage.Xaml
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

mc:Ignorable="d"
x:Class="App1.MainPage">
<StackLayout>
<!-- Place new controls here -->
<ios:UILabel Text="Hello World" TextColor="{x:Static ios:UIColor.Red}" View.HorizontalOptions="Start" />
<androidWidget:TextView Text="Hello World" x:Arguments="{x:Static androidLocal:MainActivity.Instance}" />
</StackLayout>
</ContentPage>
I had added skip Xamlcomplitation in MainPage.xaml.cs file.
[XamlCompilation(XamlCompilationOptions.Skip)]
Added in MainActivity.cs in App1.Android file.
internal static MainActivity Instance { get; private set; } // define Instance
Bit it shows error for
( 8976): Assembly Ref addref System.Xml[0xd1e768c0] -> System[0xe4b32b00]: 5
**Xamarin.Forms.Xaml.XamlParseException:** 'Position 15:52. Type MainActivity not found in xmlns clr-namespace:App1.Android;assembly=App1.Android;targetPlatform=Android'
[XamlCompilation(XamlCompilationOptions.Skip)]
Is something that you add to the Xaml backend code. Adding it to something else like in your case is likely to cause problems.

I'm creating Xamarin.Forms App and it has a service that runs in the background monitoring if any messages arrive. If a message arrives, the service should open the App.
I tried to open the App using Intent (Dependency Service) and I also tried using Xamarin.Essentials. Neither way worked.
My last attempt was with Xamarin.Essentials and gave the following error:
[Error][1]
[1]: https://i.stack.imgur.com/5jPGf.png
This is my code using Intent (Dependency Service):
//Intent (Dependency Service)
string teste = "com.saferit.saferproject";
openAppManager = DependencyService.Get<IAppHandler>();
openAppManager.Initialize(teste);
openAppManager.LaunchApp();
[enter image description here][2]

This is my native code for Android
public void LaunchApp()
{
Intent intent = new Intent();
intent.SetClassName(Package, "activity");
intent.AddFlags(ActivityFlags.NewTask);
Xamarin.Forms.Forms.Context.StartActivity(intent);
}

This is my AndroidManifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.saferit.saferproject" android:installLocation="preferExternal">
<uses-sdk android:minSdkVersion="27" android:targetSdkVersion="29" />
<!--<application android:label="SaferProject.Android"></application>-->
<application android:label="com.saferit.saferproject" android:icon="#drawable/logo">

<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />

<data android:scheme="com.saferit.saferproject" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
</manifest>
This is my attempt using Xamarin.Essential:
//Xamarin.Essentials
var appname = "com.saferit.saferproject://";
var supportsUri = await Launcher.CanOpenAsync(appname);
if (supportsUri)
await Launcher.OpenAsync(appname);
Looking for here at stackoverflow I found this question:
Open Notification list page when user clicks on navigation
I tried to implement it on my App but I also couldn't get it to work.
In all three cases the errors are very similar.
I think the problem is in the configuration of the URI of my App.
Can someone help me?
My question may sound stupid but I am struggling to achieve my result. I would like to edit and save version tage of vsixmanifest file without loosing any content. This article almost solved my purpose but it removes some of the tags.
<?xml version="1.0" encoding="utf-8"?>
<Vsix xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Version="1.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010">
<Identifier Id="Visual Test">
<Name>Visual Gallery Test</Name>
<Author>Visual Studio Demo</Author>
<Version>XXXXX</Version>
<Description xml:space="preserve">Visual Studio Gallery Demo</Description>
<Locale>1033</Locale>

<SupportedFrameworkRuntimeEdition MinVersion="4.6" MaxVersion="4.9" />
</Identifier>
<Content>
<VsPackage>XX.pkgdef</VsPackage>
</Content>
</Vsix>
Here is my gradle script
task updateExtensionManifest{
def vsixmanifestFile = "build/source.extension.vsixmanifest"
def vsixmanifest = new XmlParser().parse(vsixmanifestFile)
vsixmanifest.Identifier[0].Version[0].value="YYYYY"
def nodePrinter = new XmlNodePrinter(new PrintWriter(new FileWriter(vsixmanifestFile)))
nodePrinter.preserveWhitespace = true
nodePrinter.expandEmptyElements = true
nodePrinter.print(vsixmanifest)
}
When I execute the script it removes some of the tags defines manifest file, this is how it looks after task is getting executed:
<Vsix xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010" Version="1.0.0">
<Identifier Id="Visual Test">

</Identifier>

</Content>
</Vsix>
Some unwanted edits:
Line1 removed: <?xml version="1.0" encoding="utf-8"?>
Line2 modified to <Vsix xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010" Version="1.0.0">
Tag "Description" got edited too..
How could I avoid this edits? I just expected the version to get modified from XXXXX to YYYYY without changing any other content through my gradle build script.
That is because XmlNodePrinter.
If xml markup declaration is needed, use XmlUtil.serialize().
def vsixmanifest = new XmlSlurper().parse(vsixmanifestFile)
vsixmanifest.Identifier[0].Version.replaceBody ( "YYYYY" )
println groovy.xml.XmlUtil.serialize(vsixmanifest)

I have install MVCSitemapProvider on my MVC 3 application for breadcrumbs trail. It has auto generate following node in Mvc.sitemap.xml
<?xml version="1.0" encoding="utf-8" ?>
<mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-3.0"
xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-3.0 MvcSiteMapSchema.xsd"
enableLocalization="true">
<mvcSiteMapNode title="Home" controller="Home" action="Index">
<mvcSiteMapNode title="About" controller="Home" action="About"/>
</mvcSiteMapNode>
</mvcSiteMap>
And Following is the HTML Helper for displaying breadcrumbs
#Html.MvcSiteMap().SiteMapPath()
In my application, there is lot of controller and their action that is hectic to add all mvcSiteMapNode in mvcSiteMap of those action and question is that Is it possible to list all controller and their respective action in mvcSiteMapNode of Mvc.sitemap.xml without writting all manually.
I think the closest thing is using attributes on the methods, see https://github.com/maartenba/MvcSiteMapProvider/wiki/Defining-sitemap-nodes-in-code. Example:
// GET: /Checkout/Complete
[MvcSiteMapNodeAttribute(Title = "Checkout complete", ParentKey = "Checkout")]
public ActionResult Complete(int id)
{
// ...
}
I have a boolean property Settings.Default.MarkAsRead in the Setting.settings file, which I can access in my Ribbon class. What I'd like to do is set the value of a check box in my backstage section depending on the value of this property. Also if the user modifies it, I'll need to save the new value.
Any way I can do this?
This is my (simplified) xml:
<?xml version="1.0" encoding="UTF-8"?>
<customUI onLoad="Ribbon_Load"
xmlns="http://schemas.microsoft.com/office/2009/07/customui">
<backstage>
<tab id="MyBackstageSection" label="MyBackstageSection"
columnWidthPercent="30" insertAfterMso="TabInfo" visible="true" >
<firstColumn>
<group id="grpOne" label="Configuration">
<bottomItems>
<checkBox id="markAsRead" label="Mark as read"
getPressed="markAsRead_GetPressed" />
<button id="save" label="Save Preferences" onAction="save_Click"/>
</bottomItems>
</group>
</firstColumn>
</tab>
</backstage>
</customUI>
I didn't find a way to access the xml elements from the Ribbon_Load method, so I've created a boolean property in the ribbon class that I update using the GetPressed and OnAction callbacks:
xml:
<checkBox id="markAsRead" label="Mark as read"
onAction="markAsRead_OnAction" getPressed="markAsRead_GetPressed"/>
c#:
private bool MarkAsRead { get; set; }
public bool markAsRead_GetPressed(Office.IRibbonControl control)
{
this.MarkAsRead = Settings.Default.MarkAsRead;
return this.MarkAsRead;
}
public void markAsRead_OnAction(Office.IRibbonControl control, bool isPressed)
{
this.MarkAsRead = isPressed;
}
This is my code:
<controls:AdvancedDataGrid id="adg" dataChange="adg_dataChangeHandler(event)">
<!-- other stuff goes here -->
</controls:AdvancedDataGrid>
and in my ActionScript code:
protected function adg_dataChangeHandler(event:FlexEvent):void
{
trace(1);
}
When I edit a cell in advancedDataGrid (making the columns editable of course) it never dispatches an event. Or, in other words, my function is never called. How can I fix this?
I think that the better option for my scenario is to use an itemEditor, that has a listener put on the change event. Code looks like :
<controls:AdvancedDataGrid id="adg">
<controls:groupedColumns>
<adgs:AdvancedDataGridColumn headerText="A" wordWrap="true" dataField="name" editable="false" itemEditor="Aaa"/>
</controls:groupedColumns>
</controls:AdvancedDataGrid>
and the item editor class is here :
