Hi,

I'm experiencing strange js error in page where I've used AspxPopupControl, it's enough hardly describe all the scenario but the error seems involved when a resize event is raised from the popupcontrol.

I try to put here some information but since it's not allowed to post any attachment I'm waiting for a your suggestion to share any files you need.

Stack Trace

> _aspxGetPositionElementOffset JScript
  _aspxPrepareClientPosForElement JScript
  JScript anonymous function JScript
  JScript anonymous function JScript
  JScript anonymous function JScript
  aspxPopupControlWindowResize JScript

Code when exception is thrown

 function _aspxGetPositionElementOffset(element,isX){var curEl=element.offsetParent;var offset=0;var scroll=0;var position="";while(curEl!=null){var tagName=_aspxIsExists(curEl.tagName)?curEl.tagName.toLowerCase():"";if(tagName=="html"||tagName=="body")break;if(tagName!="td"&&tagName!="tr"){var style=_aspxGetCurrentStyle(curEl);if(style.position=="absolute"||style.position=="fixed"||style.position=="relative"){offset+=isX?curEl.offsetLeft:curEl.offsetTop;if(__aspxIE||__aspxOpera9||__aspxSafariMacOS)offset+=_aspxPxToInt(isX?style.borderLeftWidth:style.borderTopWidth);}}
scroll+=isX?curEl.scrollLeft:curEl.scrollTop;curEl=curEl.offsetParent;}
offset-=scroll;return offset;}

In particulary is element.offsetParent is null;

Now while I'm writing here I see that the problem is caused from a callbackpanel that includes the aspxPopupControl when at client side I invoke

- aspxPopControl.Show()

- and then callBackPanel.PerformCallback();

I do that since i need to update popup content plus the popup header text, so if i put the callbackpanel inside of popupcontrols it works but the header text doesn't change.

P.S (I'm using version 8.2.2)

Any suggestion will be appreciated.

Kind Regards

Hello Shogun,

For errors, please create a bug report with a sample project and steps to reproduce so the support team can investigate the issue.

I get exactly the same exeption.

I use ASPxPopupControl inside an Update Panel because I need to update it including the header but,  Below js row throws exception :

function _aspxGetPositionElementOffset(element,isX){var curEl=element.offsetParent;var

Is there any known solution for this issue ?
