I have a lot of Bindings which are relevant for source to target updates only

Question

Should I be explicity setting BindingMode=OneWay on them? (by default, bindings are set as TwoWay)

I suppose the main reason to do so is to avoid unintended target to source updates. But my bindings are mainly Visibility or IsEnabled bindings which will never have a source to target update.

Is there any other reason (e.g. performace) why it would be good practice to explicity set BindingMode=OneWay?

Hi rizzlwizzl,

I think you could refer to this article:

-->   Is there any other reason (e.g. performace) why it would be good practice to explicity set BindingMode=OneWay?

Do you mean when should we use the BindingMode = OneWay?

for example, if you have two textbox to display the same data, just one textbox could change the data source dynamically, you could set the BindingMode = OneWay to this textbox, the other one as TwoWay, then for the OneWay textbox, the data source will change the text porperty of this textbox, it could not in turn.
