how to pass value to user control.

Hi,

 

I am developing an windows application in c# using vs2010.  I am using metro frame work UI design in that. in that i am having 4 user control pane. when i click 1st user control the value passed to that user control. this same for all user controls but when i came again (2nd time) to the user control the value(argument value) is not passing but the user control is viewing.

 

The value only passing in 1st time not other times. any one help me to solve this issue. it's very urgent.

 

Thanks in advance.
