I created a user web control containing a blue panel which will pop up when user clicks on a text box. I use Modalpopupextender for this purpose. It is very simple!
When I reuse this control in a page, the blue panel shows up for a fraction when the page is loaded. This is very annoying cause I basically can't create my own modal dialog box and reuse for different pages. Is this a bug in the toolkit or do I need to add something to my control?
Thanks

I found another post which solves my problem.
You have to add "display:none" attribute to the panel style. I guess the code in AJAX control takes some time to iterate through all the controls on the page to find and hide the target panel.
