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

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?

I have two datalists. Data list 1 shows regions; data list 2 is nested in datalist 1 and shows the cities in those regions. The two datalists bind ok.
However, I'm trying to call a click event from the nested data list (2) so that when clicked, the cityID nested in datalist 2 will appear in a label.
Here is a simplified version of the code.

I have a gridview with a nested placeholder in each rows. I nested some checkboxes in each placeholders in each rows dynamically, so their ServerIDs are not the same (I dont want to use nested gridview). at the end in a button event I want to count checked checkboxes in gridview while I can not use findcontrol() method in each rows to find checkboxes due to their different ServerIDs.

Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

have a page that has a validation summary control. On this page I have a nested user control (Control1). nside Control1 is another nested control (Control2). I have a CustomValidator on a textbox inside Control2.
Although the validation works on this textbox, the error message doesn't get bound to the ValidationSummary control. Is there limitations to the ValidationSummary control with nested controls?
