I'm working on learning WPF, and I'm having an issue with my menu. The menu displays fine but when I click on a root level item, the sub menu does not appear to drop down. It still appears that I can click on where the menu item should be, and it will fire the proper event. Is there something common errors that cause this or do i need to post some source code because I'm doing something dumb?

I need to find the binding control of my TreeViewItem's parent, GetContainerFromItem gives me the parent TreeViewItem and GetParent gives me the Parent Item, but how do I get the control that is bound to the parent Item?
I'm using a custom control to display the items, and need to manipulate it from a child control...

In my silverlight application I've many pages(1,2,3...), after logged in i'm showing default page. After that if i click on any page default loading (silverlight progress like rotating a default logo with continual increment of time) is going on.
Next if i click on the any other page of same page that silverlight progress is not showing. My silverlight pages have huge data, so for loading the data it takes time to show any page without showing any progress.
I need to show any progress bar on loading the data.... is it possible to show the progress bar in all pages while loading?
1) Before you request data, show a ProgressBar.
2) If you're using a data retrieval method that reports download status, update the ProgressBar.
If no download status is available, you could set the ProgressBar's IsIndeterminate property to True.
3) When the data is received, hide and/or remove the ProgressBar.
I need to generate a grid programatically an image per cell in a grid-like fashion that could be 100 x 100 or more, so I need a high performance control that will be able to handle interacting with the grid once its loaded. I've tried a stack panel method which did work quite well but there seemed to be a bit of a performance lag on it. I'm a bit new to WPF so if you have any suggestions as to what would be best to use that's be fab
I am having the requirement like drawing the database relationship diagram.
Please find the sample image in the below path.
1. By default, each table icon is in the minimized state & is displayed as a clickable button.
2. If the user click on it, it will be maximized & all the columns displayed (with scroll, if number of columns exceeds its maximum limit)
3. The user can move the icons anywhere around the UI boundaries.
4. The user can minimize it back to an icon by clicking on the minimize botton.
5. There is a connector between related tables (primary/ foreign key relationship) Column wise connector is not required in my case. Only one connector between the related tables is required.
6. If the user clicks on the connector, the relationship details will be displayed in a popup window.
How can we implement the same in Web UI using Silverlight?
Till now, I have tried with WCF for the database connectivity & drawn few movable images (Image control with mouse event handlers) and connectors (line control) between them by created all the controls dynamically from code behind file (xaml.vb)
Kindly help us with your valuable suggestions on this.
