UserControl Layout issues in GridVirtualizingCellRenderer

[Administrator]

I am using GridVirtualizingCellRenderer to render a UserControl in a WPF Grid cell.
The UserControl contains a DockPanel which contains 3 controls. A textBox which is docked left and 2 buttons that are docked right, but when this is rendered in the grid all the controls are stacked up on Left. Any ideas?
(I have also tried using a Grid layout in the control but the result was much the same)

This works fine if I use a Templated Control in place of a UserControl

Hi Simon,

I think the UserControl that you are using in the virtualized cell is not measured fully. This happens sometimes when you use a complex control inside a cell. If you can work it out with a templated control, that should be the easiest way to workaround it.

Thanks,
