Q: 

SelectedNode in TreeView is lost when Visible=false

it seems like the treeview control in asp.net will clear the SelectedNode property, when Visible is set to false.

i want to create a dropdown with a treeview inside it, and every time i collapse the dropdown, the value is cleared!

is there a workaround/fix for that? i tried abusing the ViewState, but then i have problems with assigning the default value.

is this a bug or is this by design?

TIA
