Is there any way to remove the current time that shows when TimePicker have focus in Silverlight ?
TimePicker :
http://www.silverlight.net/content/samples/sl4/toolkitcontrolsamples/run/default.html
Category : Input > TimePicker
Simply re-template the control to remove the popup.
In Blend, add a TimePicker to your page. Right click it and select "Edit Template->Edit a copy...". In the template you will then see a "TimeUpDown" control (shown below the "RootElement" in the "Objects and Timeline" area). Right click a re-template using the same actions ("Edit Template->Edit a copy"). In the template of the TimeUpDown control, simply delete the "TimeHontPopup" control.
Compile, run, select the control and hey-presto, no more "current time" popup.
You can put these templates in a common location for use templating all the TimePicker controls that you want to remove the popup from.
