Child control not binding if not selected

[Voss Grose]

When I create RadPanelBarItem dynamically and add a custom control(Grid) only the Grid that is a child of the Selected/Expanded RadPanelBarItem gets loaded.

Once I click on a different RadPanelBarItem then the binding occurs. If I do not Select/Expand any RadPanelBarItem then none of the grid are pre-bound.

Thanks,

Example:

loop start
RadPanelBarItem rpbi = new
rpbi.Header = shift.Title.ToUpper();
rpbi.Name = shift.Title.ToUpper();
rpbi.Tag = shift.Id.ToString();

// Add Custom Reservation UserControl as a child to the RadPanelBarItem (rpbi)
ucReservationGrid grid = new ucReservationGrid();
grid.HorizontalAlignment = HorizontalAlignment.Center;
grid.VerticalAlignment = VerticalAlignment.Center;

// Load the Data
rpbi.Items.Add(grid);
grid.Load(shift);

loop end

Hello Voss,

What you observe is the expected behavior. A UI element that is not visible (e.g. the items of a RadPanelBarItem that is collapsed) will not be initialized and any bindings regarding that element will not occur until the element needs to be rendered. The above is true for the Silverlight platform as a whole and is not specific to RadControls for Silverlight.

I hope I was able to help. Let me know if you have other questions.
