What should I do to create a TextBox (and a PasswordBox) whose description stays inside of it as much as the control is empty?

Question

Hi.

I am trying to make a login interface but I want to provide controls whose description can be seen without a TextBlock. I want it to be inside of the control, the same experience provided by the standart windows live login interface on win8. How can do this in xaml using C++.

Thank you.

 

 

Answer 1

Is there a reason you want to do this without a TextBlock?

A typical way to implement such a watermark would be to place a TextBlock over the TextBox and fade the watermark in or out based on the TextBox's focus state and contents.  A more complicated variant would be to include the TextBlock in the TextBox's style and control its visibility with a VisualStateManager.

If you search for TextBox WaterMark and Silverlight you should find some examples which will get you going in the right direction.

you can use a textblock over a text box , when the text block is tapped you changed it's visibility to collapsed and set the focus of text box to keyboard.
