Wpf – A TwoWay or OneWayToSource binding cannot work on the read-only property


I've a read only property I need to display in a textbox, and getting this error at runtime. I've set IsEnabled="False", IsReadOnly="True" – no luck.
Other searches say the readonly should fix it, but not for me.
I've got an ugly workaround by adding a dummy setter…

Best Solution

It's hard to guess without code, but you should be able to set the BindingMode to OneWay.

<TextBox Text="{Binding Path=MyProperty, Mode=OneWay}" />

or from code:

Binding binding = new Binding();
binding.Mode = BindingMode.OneWay;
