Looping through dynamically build form

Question

Hi,

I have created a questionnaire in C# and when the user has entered their responses I want to capture the answers and save to the database.

I am building the content in codebehind and putting it into a placeholder on the page.

I can get a handle on the placeholder

PlaceHolder a = (PlaceHolder)FindControl("PlaceHolder1");

But when I then try to access the textboxes within the placeholder it says it has no controls!

Any help would be appreciated

Thanks Richard

You're going to need to rebuild your dynamic control structure every page request.

The server can build all the static control structures based off of your ASPX, and then fill their values from the posted data. Since you added your own additional controls, though, you have to re-add them if you want to find their values again.
