Detecting tap on different controls inside a listview cell
Two questions:
In Xamarin.Forms, I have a listview. Each item is a ViewCell containing button, labels, images etc.
First, I want to detect tap on each item inside a ViewCell. Meaning tap on label, tap on image. All separately. How do I do this?
Secondly, how do I uniquely identify my labels/images inside each item so that I know exactly which label/image was tapped since a list view will have multiple items each having its own label/image.
Thanks.

Problem with add view to RelativeLayout in loop
Good day!
I have some strange problem with code (I put only important lines here):
...
RelativeLayout r;
Image[] ims
...
{
r = FindByName("relforimages");
float width = 400f, height = 300f;
ims = new Image[2];
for (int i = 0; i < 2 ; i++) {
ims[i] = new Image {
Aspect = Aspect.AspectFit,
HorizontalOptions = LayoutOptions.Center,
VerticalOptions = LayoutOptions.Center
};
ims[i].Source = ImageSource.FromFile(localPathyn);
r.Children.Add(ims[i], ()=> new Rectangle(width * i * 0.1f,
height * i * 0.1f,
70f, 70f));
}
After this I see only last image in RelativeLayout. Even I increase count of images to 10 (for example) nothing happens - i see only LAST image
Question: is it possible (in xmarin) to use array element for add view to layout dynammically? if it's possible - what is mistake i do?

Azure app service - Running Xamarin project (Xamarin.Forms) with SQL Azure
Hello.
I’m trying to run the the Xamarin project downloaded from the Azure App Service (Deployment --> Quickstart --> Xamarin.forms).
When the app service is configured with sqllite, everything runs fine. I can see all the records inserted on Azure database, on the app service trough “Easy tables”, and I can get (read) all the records from Azure to the application (droid, ios and uwp)
When the app service is configured with a connection string to SQL Azure, I can’t do nothing (insert rows, get rows, etc), but, trough the Azure “Easy tables”, I can creat the table I need to run the projet (todoitem) – it means the connection is correct, I guess.
Connection String parameters:
NAME: MS_TableConnectionString
VALUE: Data Source=tcp: srvmyapp.database.windows.net,1433;Initial Catalog=DBmyapp;User ID=user@srvmyapp;Password=mypassword
TYPE: SQL Azure
Thank you for helping.

Gesture in ViewCell will not fire Completed in StatusType if vertically scrolled.
Hi all, I've applied a PanGesture/ SwipeGesture in a ViewCell, and I found that only the gesture is horizontal, else the Completed will never be triggered. I guess the parent listview maybe capturing the gesture when scrolling the listview vertically. Anyway to work around it? Thanks.

Update AbsoluteLayout bounds in parent Page from ContentView
Hi all,
I have a custom control name ButtonX (actually is a ContentView which contains few labels & image). This button is placed inside an AbsoluteLayout of MainPage. When user clicks on this button, I would like to update its position or size by using AbsoluteLayout.SetLayoutBounds method. But it doesn't work. Remember that, I update the bounds in ButtonX code, not in the MainPage code.
I have no idea how to do that, could you please help me to figure out the cause?
Thanks & best regards,

Font loading Issue
Hi,
I'm receiving the following error on Android and I'm unclear as to what to check : E/FontFamily(24205): Error mapping font file Fonts/Montserrat-Light.otf
I've verified that the font is an AndroidAsset, in the folder, and can be read using the following:
var font = Typeface.CreateFromAsset(Assets, "Fonts/Montserrat-Light.otf");
I think I might be doing something wrong in my App.Xaml:
<OnPlatform x:Key="FontLight" x:TypeArguments="x:String">
<On Platform="iOS" Value="Montserrat-Light" />
<On Platform="Android" Value="Fonts/Montserrat-Light.otf" />
</OnPlatform>
And the control I'd like to style:
<Style x:Key="TransparentEntry" TargetType="control:TransparentEntry">
<Setter Property="TextColor" Value="{StaticResource Purple}" />
<Setter Property="FontSize" Value="{StaticResource Small}" />
<Setter Property="FontFamily" Value="{StaticResource FontLight}" />
<Setter Property="BackgroundColor" Value="LightSkyBlue" />
</Style>
The behavior in the UI is that the carot is available but typing is blank. Any guidance would be appreciated.

Set dynamic height for multiple webviews in a view possible?
I use a customrenderer for webview, found in this forum , that reads out the height of the content and set the the webview height. The problem is, i have to use many webviews on one page, that are bind to HTML sources, so the height is all different and the customrenderer only set the height for the last webview that is rendered. All other webviews are ignored. Here is the code of the Customrenderer i use for Android. How can i set the height dynamic for all webviews?
<br />
public class ExtendWebViewRenderer : WebViewRenderer{<br />
static ExtendedWebView _xwebView = null;<br />
WebView _webView;</p>
<pre><code>class ExtendedWebViewClient : Android.Webkit.WebViewClient
{
public override async void OnPageFinished(WebView view, string url)
{
if (_xwebView != null)
{
int i = 10;
while (view.ContentHeight == 0 && i-- > 0) // wait here till content is rendered
await System.Threading.Tasks.Task.Delay(10);
_xwebView.HeightRequest = view.ContentHeight;
}
base.OnPageFinished(view, url);
}
}
protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.WebView> e)
{
base.OnElementChanged(e);
_xwebView = e.NewElement as ExtendedWebView;
_webView = Control;
if (e.OldElement == null)
{
_webView.SetWebViewClient(new ExtendedWebViewClient());
}
}
}
