Description

i'm trying to disable a button based on an Entry's Text.Length but it won't get disabled at startup when the entry is empty, but then when i type in the entry and clear it out, the button gets disabled, i tried using DataTriggers and also binding the Button.IsEnabled to Text.Length using a converter but none of them work at startup

Steps to Reproduce

either use this:

<Button
    Command="{Binding AddSectionCommand}"
    CommandParameter="{Binding Section}"
    IsEnabled="{Binding Source={x:Reference txtTitle}, Path=Text.Length, Converter={StaticResource lengthConverter}}"
    Text="Save"/>

or this:

<Button
    Command="{Binding AddSectionCommand}"
    CommandParameter="{Binding Section}"
    Text="Save">
    <Button.Triggers>
        <DataTrigger
            Binding="{Binding Source={x:Reference txtTitle}, Path=Text.Length}"
            TargetType="Button"
            Value="0">
            <Setter Property="IsEnabled" Value="False" />
        </DataTrigger>
    </Button.Triggers>
</Button>
