hello i am having a problem with a composite control i have developed and nobody as yet can help me solve this. it is a dual menu that basically swaps items between 2 listboxes <BR><BR>basically if i place multiple instances of my control on the page then they work ok. but if i put those instances inside placeholders then change the placeholders visibility depending upon user selection then my listboxes are losing their state( I think). <BR><BR>i have put a .zip file here: http://www.fidgetbrain.com/test/control.zip <BR>it contains my control code, a dll and 2 web pages. 1 works the other uses placeholders and you will see my listboxes will lose their state. <BR><BR>p.s. forget the active ddl at the bottom its not related to this demo <BR><BR>this has me stumped. can anyone help me please? thanks.
