Positioning the Edit Form Popup

[FireHolster]

I am Using a editform popup to display some hyperlinks. to position the popup I am using the clientevent

 

<

 

 

ClientEvents OnPopUpShowing="PopUpShowing" />

 

the Popupshowing method resides in another java script file. I am using the samescript as mentioned in http://www.telerik.com/help/aspnet-ajax/grid-center-popup-edit-form.html

but for some reason the

var

 

 

popUpHeight = popUp.style.height.substr(0, popUp.style.height.indexOf("px")); is coming empty.

I am not sure why? can someone please help me in here.

what i am doubting is that i am having a usercontrol binded to the popup and it gets build up after the script is trigered. so is causing the height to be empty.
