Issue with SwipeView and Listview
I only want to display the TopItems (Swipe down) if my ListView is also on top position "1". I would like to implement my own "Pull to Refresh" functionality, but the function is also active when I just scroll up (by Swiping down).

Xamarin forms: Webview video auto pausing is not working
I am using a webview for playing the video. I need to pause it programmatically in certain situations. For this, I am using the following code but which is not working.
My code:
string pausefunctionString = @"var videos = document.querySelectorAll('video');
[].forEach.call(videos, function(video) { video.pause(); });
";
web_view.Eval(pausefunctionString);
I got the above solution from this thread.
I am using HTML data as the content of webview:
Webview code:
string htmlData = "htmldata"; var htmlSource = new HtmlWebViewSource(); htmlSource.Html = htmlData; advanced_web_view.Source = htmlSource;
I have uploaded a sample here.
Video is not auto pausing in android and windows.

Send json string including Group column
As i read in documentation i need to create a structure as follow, for having a group column in my listview.
public class Group : List<Body>
{
public string Title { get; set; }
public Group(string title)
{
Title = title;
}
}
public class Body
{
public string Name { get; set; }
}
private void Button_Clicked(object sender, EventArgs e)
{
var items = new List<Group> {
new Group("Title")
{
new Body { Name = "Dimitris" } }
};
var jsonstring = JsonConvert.SerializeObject(items);
}
The problem is that when i am serialize this list, then my result is:
[[{"Name":"Dimitris"}]]
It doesn't include Group Column. Is there any way which i can fix that? Or i must send from server a single list, and then to create a structure as above in my client's pc?
Example
var items=JsonConvert.DeserializeObject<List<Body>>(jsonstring);
foreach(var item in Items)
{
var newItems = new List<Group> {
new Group(item.Title)
{
new Body { Name = item.Name } }
};

Apple rejected my Xamarin.Forms iOS App for usage of non-public API which I don't use
I have an App that is under development using Xamarin. Forms and I have submitted more than 40 beta until now and it works fine, randomly in the last week I have started getting rejected from App with the following error
The app references non-public selectors in Appname.iOS: addTemporaryAttribute:value:forCharacterRange:, addTemporaryAttributes:forCharacterRange:, behaviorWithType:, defaultBaselineOffsetForFont:, defaultLineHeightForFont:, finished, greekingThreshold, horizontalCornerRadius, initWithSource:convolutionState:weights:, initWithType:, postSession:didAddPlayer:, postSession:didReceiveData:fromPlayer:, postSession:didReceiveMessage:withData:fromPlayer:, postSession:didRemovePlayer:, postSession:player:didChangeConnectionState:, postSession:player:didSaveData:, preferredMetalContext, removeData:, removeTemporaryAttribute:forCharacterRange:, setGreekingThreshold:, setHorizontalCornerRadius:, setIsPrimary:, setShouldAntiAlias:, setUUID:, setVerticalCornerRadius:, shouldAntiAlias, temporaryAttribute:atCharacterIndex:effectiveRange:, temporaryAttribute:atCharacterIndex:longestEffectiveRange:inRange:, temporaryAttributesAtCharacterIndex:effectiveRange:, temporaryAttributesAtCharacterIndex:longestEffectiveRange:inRange:, textContainerChangedTextView:, toolTip, usesBackgroundSession, verticalCornerRadius
Also, I have seen a lot of issues since the last VS2019 for mac 2 weeks ago
I have found that several ppl got the same issue as the ones here, but neither solution solved my issue
Which I don't and don't understand the problem, I have already submitted an email without a reply until now, does anyone encounter the same issue?

how to make background blurry for a view?
is it possible to make blurred effect on grid or stacklayout or frame? i have a view using absolutelayout as below. So basically Grid is overlapping listview with transparent background but I want this background to blurry or not 100% visible. I couldnt achieve that using different BackgroundColor tones of black and transparency. I couldnt achieve using Opacity. Anyone know if it is even possible?
<AbsoluteLayout VerticalOptions="FillAndExpand">
<ListView BackgroundColor="White" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand"
</ListView>
<Grid BackgroundColor="#80000000" InputTransparent="False" AbsoluteLayout.LayoutFlags="All" AbsoluteLayout.LayoutBounds="0,0,1,1" >
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Label Text="sometext" Grid.Row="1" TextColor="White" HorizontalOptions="Center" FontAttributes="Bold" />
</Grid>

Add left padding to entry
Is there an easy way to add padding to the left on an entry so the text doesn't start right up against the edge? I know I could do a boxview or something and hack it to make it be similar, but I feel like there has to be an easier way since it's a very common thing to do.

Is it possible and/or advisable to restart an App from code behind on Button selection?
I have a data collecttion type of App.
On a 'create new' button, is it possible and/or advisable to restart an App from code behind on Button selection?
On 'restart' its a completely new refresh with no need for any information or settings from previous entries.
My default approach is to reset the Form Controls 1 by 1. It's a tad tedious.
Many thanks

Display placeholder image when image does not load of UriImageSource
Hi
I am using a remote uri as a source for an Image in Xamarin forms using a UriImageSource. I want to display a placeholder image/control when the remote image does not exist, but cant find a nice way to do this. I thought IsLoading might be the one but this is set to false once it succeeds or fails to load the image, do I have test if the remote image exists, seems a little over kill making another Http request just to determine if it doesn't exists and show a placeholder?
