Masks do not work starting with v.20.2

Hello,

Thank you for your files. We analyzed them and reproduced this behavior on our side. Now, we are working on this issue and once we obtain any results, we will notify you.

As a workaround, I recommend you replace the following line

C#
this.txtFirstName.Properties.Mask.EditMask = "(\\p{Lu}|\\p{Z}|\\-)+";

with this

C#
this.txtFirstName.Properties.Mask.EditMask = "((\\p{Lu}|\\p{Z}|\\-)+)?";

In other words, all you need is to wrap your current mask to brackets - (mask)?.

Additionally, I noticed that you are using individual bindings for your FirstName and LastName TextEditors:

C#
fluentAPI.SetBinding(txtFirstName, x => x.EditValue, x => x.FirstName);
fluentAPI.SetBinding(txtLastName, x => x.EditValue, x => x.LastName);

I would like to note that it is not necessary to additionally create such an individual binding when using data-bindings.

Should you have additional questions, let me know.

The reason for the bindings is to give the ViewModel a chance to react to changes to data. For example, in an editor's EditValue:

C#
// ViewModel

public virtual string FirstName { get; set; }

public void OnFirstNameChanged()
{
    this.RaiseCanExecuteChanged(x => x.Accept());
}

Is there an alternative method that does not require the use of individual bindings in the View?

Hello,

In order not to mix several questions in one thread, I have created a separate ticket on your behalf (T944883: MVVM - How to update ViewModel properties once a user changes values in corresponding bound TextEditors). It has been placed in our processing queue and will be answered shortly.
