You'll probably need separate event handlers for each control if you want different behaviors. Or perhaps I'm not understanding right?

Dirwaz commented 4 years ago

Greetings,

This is exactly my problem but i have put the 2 controls in 2 different views.

dotMorten commented 4 years ago

I'm not really understanding the problem. Why can't you have two different event handlers - one for each control?

Dirwaz commented 4 years ago

i did in my code and the same issue exists.

dotMorten commented 4 years ago

The code above both controls uses the same event handlers AutoSuggestBox_TextChanged, AutoSuggestBox_QuerySubmitted and AutoSuggestBox_SuggestionChosen.

Dirwaz commented 4 years ago

The code above both controls uses the same event handlers AutoSuggestBox_TextChanged, AutoSuggestBox_QuerySubmitted and AutoSuggestBox_SuggestionChosen.

check my code in my issue and you will find the event handlers are different.

dotMorten commented 4 years ago

I don't see the difference. They both point to the same set of handlers:

   <teste4:SuggestBoxCustom            
        PlaceholderText="Qual o usuario deve aparecer?"  
        WidthRequest="200"        
        TextChanged="AutoSuggestBox_TextChanged"
        QuerySubmitted="AutoSuggestBox_QuerySubmitted"
        SuggestionChosen="AutoSuggestBox_SuggestionChosen"/>

     <teste4:SuggestBoxCustom            
        PlaceholderText="Qual o usuario deve aparecer?"  
        WidthRequest="200"        
        TextChanged="AutoSuggestBox_TextChanged"
        QuerySubmitted="AutoSuggestBox_QuerySubmitted"
        SuggestionChosen="AutoSuggestBox_SuggestionChosen"/>

I tried with different events.

I also tried to change the focus, without success, in the example sent: yes the same event is being used but I tested it with different events without success.

I will try to explain better: if you add two components in the same view. When I type in one of them, the other receives the same values.

dotMorten commented 4 years ago

Perhaps I'm not understanding what your issue is. You said you just wanted to unlink the events.

Perhaps a simple app that reproduces the issue plus a screen recording of what you're seeing might help

dotMorten commented 4 years ago

Btw, there's a sample in the sample repo with two controls in the same and that works just fine

dotMorten commented 4 years ago

Both "AutoSuggestBox_QuerySubmitted" and "AutoSuggestBox_SuggestionChosen" change the same two labels so naturally both controls would do the exact same thing.

Thanks but the video is private so I can't see it

eduardovedelago commented 4 years ago

i fix the link https://www.youtube.com/watch?v=8tWnaSpRRas

dotMorten commented 4 years ago

Thanks! That behavior makes absolutely NO sense. I'll try and debug it a bit tonight. Have you had a chance to debug and figure out where the changes are coming from yet?

eduardovedelago commented 4 years ago

I've tried without success

Apparently there is a link between the events or a single instance.

however, by the logic of how the components are instantiated, it really doesn't make any sense.

eduardovedelago commented 4 years ago

the change_text event is called multiple times

dotMorten commented 4 years ago

Figured it out. Fixed in master

eduardovedelago commented 4 years ago

thanks
