Web Forms :: Can't Find A Control On Webpage

Jan 19, 2010

I have a web page "Survey.aspx"

This page is in a MasterPage.

In survey.aspx, I put a PlaceHolder.

In this place holder, I dynamically add a usercontrol (for each question in a survey). That usercontrol for now is just a simple Panel with a radiobutton. For the test, I have 2 questions, so the usercontrol will be inserted 2 times in my PlaceHolder.

On a submit button added in my Survey page, I try to retrieve the value of both the radio, but I just cant find the control.

I made a recursive function to loop through all the controls, I find the "PlaceHolder1" controls, but it has no child controls. Where are the 2 panels for each questions .. both containing 1 radio.

I see them on screen, but just can't find them in my coding.

This is my Survey.aspx layout code

This is my usercontrol layout code

How To Find What ActiveX Control Is Referred On A Webpage

Mar 4, 2010

I have developed a web application (ASP.NET Web Forms). One of my customer has very restrictive policies. When he accesses the web page, IE shows this message:

Your security settings do not allow Web sites to use ActiveX controls installed on your computer. This page may not display correctly.

As far as I know, we don't use ActiveX controls on our page. I did a "View > Souce" and did not find anything suspect.

How can I find what part of my page refers to an ActiveX. The application uses jQuery and a few jQuery plug-ins. Is there a tool/add-in like "Fire Bug" that I can use to list the ActiveX controls referred on a page?
