Thanks guys, Bit of reading and playing and have got it working by doing exactly that. Wasn't sure why setting it to PropertyChanged wasn't working but it looks like the only two values (in SL3.0) are Explicit and default. There's only one place where I want the value updated (and it hasn't lost focus) so doing the UpdateSource is fine and works.
thanks again! :) cheers, Stephen On Wed, Apr 14, 2010 at 2:37 PM, Miguel Madero <m...@miguelmadero.com> wrote: > The binding is updated on lost focus not on TextChanged, however you can > force this doing something like this on your keypress: > txt.GetBinding(TextBox.Text).UpdateSource(); > > On Wed, Apr 14, 2010 at 4:06 PM, Jordan Knight > <jordan.kni...@readify.net>wrote: > >> Maybe have a play with UpdateSourceTrigger and BindingExpression… >> >> >> >> >> http://msdn.microsoft.com/en-us/library/system.windows.data.binding.updatesourcetrigger(VS.95).aspx >> >> >> >> >> >> >> >> *From:* ozsilverlight-boun...@ozsilverlight.com [mailto: >> ozsilverlight-boun...@ozsilverlight.com] *On Behalf Of *Stephen Price >> *Sent:* Wednesday, 14 April 2010 3:57 PM >> *To:* ozSilverlight >> *Subject:* Closing childwindow >> >> >> >> Hey all, >> >> >> >> I've hit what seems to be a race condition, I've got a login usercontrol >> which uses a ChildWindow. when the user presses enter on the passwordbox I >> check if the key == key.enter and if the password is not blank I set the >> this.DialogResult = true; which seems to be closing the ChildWindow before >> the databinding has updated the underlaying property.
