WinUI3: How to override metadata for a dependency property

Question

Hi,

I got a class called CustomTextBox which inherits from TextBox.

How can I override an event when the value of "IsReadOnly" property is changed? I want to do something else from code behind when this value is changed.

I have searched online and there is a method called "OverrideMetadata", but it is available in WPF, not WinUI3.

Thanks.

Hello,

Welcome to Microsoft Q&A!

As far as I'm concerned, you couldn't override metadata for "IsReadOnly" property directly, and there is no similar method in winui3.

I suggest you could try to implement your own dependency properties for "IsReadOnly" property. For more details you could refer to the Doc: Custom dependency properties.

Thank you.
