Cannot set Picker Default value-CodePudding

I have a picker on my Xamarin form, bound to a list, and I would like that it has the first item of that list already selected when the form is opening.

My list looks like this

Languages = new List<string>();
Languages.Add("English");
Languages.Add("Nederlands");
Languages.Add("русский");

I tried like this

<Picker x:Name="PickerLanguage" Title="" 
        TitleColor="#004973" 
        FontSize="24" 
        ItemsSource="{Binding Languages}"
        SelectedIndex="0"
        SelectedItem="English">
</Picker>

and like this

<Picker x:Name="PickerLanguage" Title="" 
        TitleColor="#004973" 
        FontSize="24" 
        ItemsSource="{Binding Languages}"
        SelectedIndex="0"
        SelectedItem="0">
</Picker>

Both attemps above are based on the answer of this question

But is does not works.

How can I have it so that when the form opens, English is set as selected item/index already ?

CodePudding user response：

create a property for your selected item in your c# then bind it to your picker :

private string selectedObj;
public string SelectedObj
{
  get{ return selectedObj;}
  set{ selectedObj= value ; 
     PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("SelectedObj"));}
      
}

then you can set your value to the selected object any place in your code:

SelectedObj = "English";

then bind it to picker in xaml:

<Picker x:Name="PickerLanguage" Title="" 
        TitleColor="#004973" 
        FontSize="24" 
        ItemsSource="{Binding Languages}"
        
        SelectedItem="{Binding SelectedObj}">
</Picker>
