Image not getting the Class ID - Xamarin Forms
0
I have several images in my XAML as follows (for this example I included two images).
<StackLayout Orientation="Horizontal" HorizontalOptions="Fill" Padding="0,5,0,5">
<Image x:Name="Image1" ClassId="Binding Image1" Source="tickoff.png" HeightRequest="18">
<Image.GestureRecognizers>
<TapGestureRecognizer
Tapped="SelectedImage"
NumberOfTapsRequired="1" />
</Image.GestureRecognizers>
</Image>
<Label Text="Asian Foods" FontSize="16" HorizontalOptions="Center" Margin="5,0,0,0"
TextColor="StaticResource greyishBrown"/>
</StackLayout>
StackLayout Orientation="Horizontal" HorizontalOptions="Fill" Padding="0,5,0,5">
<Image x:Name="Image2" ClassId="Binding Image2" Source="tickoff.png" HeightRequest="18">
<Image.GestureRecognizers>
<TapGestureRecognizer
Tapped="SelectedImage"
NumberOfTapsRequired="1" />
</Image.GestureRecognizers>
</Image>
<Label Text="Japanese Foods" FontSize="16" HorizontalOptions="Center" Margin="5,0,0,0"
TextColor="StaticResource greyishBrown"/>
</StackLayout>
I want to check what image has been clicked by the user. Fort this I'm using ClassId. I have included ClassIds in all images. This has a single method in code behind and I'm accessing classId from there.
But I'm not getting the Id when user clicks an image. I'm new to C# and Xamarin Forms. Could someone help me.
public void SelectedImage(object sender, EventArgs eventArgs)
Image image = (Image)sender;
string imageString = image.ClassId;
DisplayAlert("Test", imageSender.ClassId,"OK");

are Image1 and Image2 string properties on your BindingContext?

if you just want to assign a static value to ClassID, then just use a string "Image1" or "Image2". If you want to actually bind ClassID to a value on your model, then you will need to specify the name of a public property in the binding expression

Nov 12 at 4:33
I removed that and added as ClassId="Image2" , now I'm getting cast error. Not working
