here code below. thanks

public partial class userroledetails : usercontrol {     public string labelname { get; set; }      public userroledetails()     {         initializecomponent();          this.txtroletitle.text = labelname;     } 

}

you setting value of txtroletitle.text in constructor, @ point of assignment labelname property not have value.

i think need @ making labelname dependency property , binding txtroletitle control in user control's xaml. take @ example : http://stevenhollidge.blogspot.co.uk/2012/03/dependency-properties-in-user-control.html
