I have a popup window containing a custom component which takes a wile to render.
The component contains 12 lists and the list have about 30 items which are all vissible since the listrenderer is a small rectangle.
The problem i have is that the popup is shown when the component is done rendering.
This takes about 2-5 seconds. So when a user clicks on the button to open the popup he has to wait (and gets the feeling nothing happens).
Is there a way to open the popup instantly and than show a loading bar until the component is rendered?
I cannot find a good event to use to know when the component is rendered completly.
