Would make forms look great on UWP apps!
Nice control with great visuals.
I actually already have this control from another project. I have it for PasswordBox too. I wonder if this is a little too specific/niche though.
@ScottIsAFool how is it implemented, is it an extended TextBox?
I think this control don't bring new functional to the ground, it's just a Style. On the other hand there are a material design library for WPF, (https://github.com/ButchersBoy/MaterialDesignInXamlToolkit). I think we need to contribute to this repo for the UWP support.
Please consider to not include every idea to this repo.
@totht91 actually that library already has UWP support.
@nmetulev Have a look at:
PasswordBox: https://github.com/MediaBrowser/Emby.Mobile.Universal/blob/Dev/Emby.Mobile.Universal/Controls/EmbyPasswordBox.cs Style: https://github.com/MediaBrowser/Emby.Mobile.Universal/blob/Dev/Emby.Mobile.Universal/Themes/Generic.xaml#L1839-L2151
TextBox: https://github.com/MediaBrowser/Emby.Mobile.Universal/blob/Dev/Emby.Mobile.Universal/Controls/EmbyTextBox.cs Style: https://github.com/MediaBrowser/Emby.Mobile.Universal/blob/Dev/Emby.Mobile.Universal/Themes/Generic.xaml#L1549-L1837
For those who were interested in this, the above code links I provided, looks like this https://twitter.com/scottisafool/status/650431791355031554/photo/1
I think you should be able to accomplish this with a standard TextBox and changing how the header looks and moving it when Text.Length changes from 0 to 1
This control as mention is specific and niche. For those interested please look at @ScottIsAFool example.
