Xamarin Forms DisplayActionSheet Outside Touch Error
0
I have a Displayactionsheet for confirmation before deleting item from listview.
var action = await DisplayActionSheet("Delete Item !", "Yes", "No", "Press YES to delete item");
Debug.Write(action);
if (action.Equals("Yes"))
{
var image = sender as ImageButton;
var item = image?.BindingContext as Product_Value2;
var vm = BindingContext as ItempageVM;
vm?.Delete.Execute(item);
}
else if (action.Equals("No"))
{
}
If i choose yes or no, i am getting the desired result.when i press outside this box, shows this error:
Attempted to finish an input event but the input event receiver has already been disposed.
Unhandled Exception:
System.NullReferenceException: Object reference not set to an instance of an object.
How to handle this exception?

If you press outside, action is null, so you can check for null and do whatever you desire
var action = await DisplayActionSheet("Delete Item !", "Yes", "No", "Press YES to delete item");
if(action == null)
{
//Your logic here
}
else if (action.Equals("Yes"))
{
var image = sender as ImageButton;
var item = image?.BindingContext as Product_Value2;
var vm = BindingContext as ItempageVM;
vm?.Delete.Execute(item);
}
else if (action.Equals("No"))
{
}
