MaskedTextBox OnApplyTemplate problem

Sep 29, 2012 at 9:57 PM

MaskedTextBox has a bug hard to catch but easy to reproduce (well, it is easy now ;) ):

Put a TabContreol on the xaml, on the first tab put a button and on the second a maskedtextbox (with any mask). On the button click, set the masktextbox value. Now if you run the application and click the button *before* open Tab 2, the value gets setted on the control but when you open Tab 2, it gets reseted. If you open Tab2 before and then click the button, it works fine.


I found out that removing line 288 on MaskedTextBox.cs fixes this but I am not sure if there is a collateral effect.


public override void OnApplyTemplate()    
      ResolveMaskProvider( Mask );      
      //UpdateText( 0 );    <-- commented this
