Web User Control in AJAX Popupcontrolextender

Question

hi friends,

I have a problem with web user control with firing events using AjaxPopupcontrol.

my need is, when I mouse hover the text - some other text will display as a

popuptext from database. this is working well in normal aspx pages.

but when I place the popupextenwer and other controls to the Web User Control and

place the web user control to one aspx page. it doesn't work. mouse hover worked but not getting values from database. it returns the following error message!!!


Web Service Call Failed : 500

can any one explain how to do this. giv me a code for this.
