A TwoWay or OneWayToSource binding cannot work on the read-only property
🔌💔 Why TwoWay or OneWayToSource Binding Fails on Read-Only Property? Find Easy Fixes! 🛠️
So, you've encountered some funky issues while trying to bind a read-only property in your app, huh? 😫 It's a perplexing problem, but fear not! Your friendly tech writer is here to shed some light on this matter and help you find the solution that saves the day! 🦸♂️💡
The Mystery Unveiled
When you set the IsEnabled and IsReadOnly properties to True on your textbox, you'd naturally expect everything to work smoothly, right? But hold your horses! 🐎 It seems that this combo alone isn't enough to make the binding magic happen. 😕
You're not alone in your confusion; others have faced similar challenges. They've suggested that using the readonly modifier should do the trick. However, it turns out that this approach doesn't work for everyone. 🤷♀️
The Ugly Workaround
Desperate times call for desperate measures, right? So, to make things work, you added a dummy setter. Well, that's a solution of sorts, but let's be honest, it's not the most elegant one. It's like putting a band-aid on a broken bone. 🩹😬
Time for Solutions! 🚀
👉 1. Create a Dependent Read-Only Property
Instead of directly binding your read-only property to the textbox, you can create a dependent read-only property in the code-behind. This dependent property would return the value of your original read-only property. You can then bind this dependent property to the textbox.
public string OriginalProperty => "I'm read-only!";
public string DependentProperty => OriginalProperty;In your XAML, you can now bind DependentProperty to your textbox:
<TextBox Text="{Binding DependentProperty}" IsEnabled="False" IsReadOnly="True" />Voilà! Your textbox is now displaying the value of your read-only property without any errors. 🎉
👉 2. Use OneWay Binding
If you don't need TwoWay or OneWayToSource binding, you can simply use OneWay binding. It allows you to display the value of your read-only property without worrying about updating it in the source.
<TextBox Text="{Binding OriginalProperty, Mode=OneWay}" IsEnabled="False" IsReadOnly="True" />By using OneWay binding, you're saying, "Hey, I just want to show this value, no need to worry about changing it!" Easy peasy! 🍋😎
