I find out a very wired breadcrumbs issue, I create a custom feature and add into the root and i have few configuration pages page link put in my admin dashboard page,

suppose the level of breadcrumbs is 

customfeaturepagename > mydashboardpage > 

but when every time i click in any pages in my admin dashboard page the breadcrumbs link to my home page which is default mojo html page.

Home >  mydashboardpage 

 i am using the code in my configuration page 

Control c = Master.FindControl("Breadcrumbs");
if (c != null)
{
BreadcrumbsControl crumbs = (BreadcrumbsControl)c;
crumbs.ForceShowBreadcrumbs = true;
crumbs.AddedCrumbs = "+ ("/Accreditation/Admin/admindashboard.aspx?pageid=")
+ pageId.ToInvariantString()
+ "&mid=" + moduleId.ToInvariantString()
+ "' class='unselectedcrumb'>" + customResources.admindashboardname
+ "";
}
