Silverlight

Hi All,

I designed one Page loading control from user control, which has some animation of rotation & color changing. I am showing that Loading control (user control) on Main Page while navigating the pages. Means while page got loaded completely user is able to see page loading control rather than blank screen.

Means if I clicked the menu button, the visibility of loading control is set to be Visible & then after the concern page loading event is got fired. But unfortunately it's happened adversely. Kindly guide me how to achieve the goal. The code is also pasted below for reference.

ldgWnd.Visibility = Windows.Visibility.Visible
HideCoverflowMenu(False)
Dim DrvTrnYr As New GlbNetDerivative()
host.Add(DrvTrnYr)
DrvTrnYr.Show(startPoint)

I used Floating Window for pages. & Host to showing the floating window of Jevgenij Pankov The link of floating window is FloatingWindow - Multi-windows Interface for Silverlight 4[^]

Thanks & Regards
Anil
