Not work binding

danrer · 05 May 2020, 17:34

I can't understand why I don't have some BINDING elements working, when loading it gets an element and takes all the necessary information from it, but then it stops responding to SelectedResearch changes.

Although it is changing, this can be seen from the progress of the bars.

Does not work

        <TextBlock HorizontalAlignment="Left" Margin="391,41,0,0" TextWrapping="Wrap" Text="{Binding SelectedResearch.Name}" VerticalAlignment="Top" Height="100" Width="443" FontSize="24"/>
        <Image Source="{Binding SelectedResearch.Icon, Converter={StaticResource Texture2DToTextureSourceConverter}}" HorizontalAlignment="Left" Height="100" Margin="286,41,0,0" VerticalAlignment="Top" Width="100"/>
        <TextBlock HorizontalAlignment="Left" Margin="286,148,0,0" TextWrapping="Wrap" Text="{Binding SelectedResearch.Description}" VerticalAlignment="Top" Width="548" Height="127"/>
        <ListBox
            ScrollViewer.HorizontalScrollBarVisibility="Disabled"
            ItemContainerStyle="{StaticResource QueueRequirementItemStyle}"
            ItemsSource="{Binding SelectedResearch.Requirements}" Margin="286,280,293,10"/>
