hi,
first let me complement your control, it looks good and it's easy to use and code.
i want to try and do something with it, and i don't really know where to begin.
when Collapsed i want the expander to look different and be a little bit shown and put some buttons on it with icons,
something like the example i've attached (in both pictures the expander is Expended but you get the idea i think)
i thought about using its' events (PreviewCollapsed?) or something like that but i wonder if there is a better way.
can you help in some info on how to accomplish this?
thanks in advance.
Lior.

Hi,
I have a simple application that show grid to the user and according to the user selection i refresh the grid.
when i refresh the grid i do the following:
1) create a new list with the new items
2) grid.ItemsSource = newlist;
if the new list has more than 1000 objects the refresh takes several seconds.
How can i improve the refresh time of the grid ?
I also tried to work with ObservableCollection and update it instead of binding a new list, but it still took several seconds.
Thanks you,
Ofer
