Yes RenderInvisibleControls is set to true.
I put my code back in the AsyncDblClick on the IWListbox again to make sure.. and with it in there, theChecklistbox code that sets it to visible runs.. but the checklistbox never shows. Still only works with this code in the OnClick event.
Just to make sure also, with this code still in the Async Event of IWListbox, i dropped a dummy IWbutton on the form.
I set a asyncclick event with just begin; {} end; ... thats it... when i click it.. nothing happens like i thought..
but if I remove the asyncclick event from the button, and set an OnClick event, with just begin; {} end; , when i press
the button, now the Checklistbox appears finally, with all my values i put into it.
