RegisterHiddenField and trace

[Kevin Spencer]

1) Only server controls can appear at the trace page? Is it possible to
make

regular html controls appear at the trace page?

RegisterHiddenField doesn't create a Control. It adds HTML to the page that
renders a hidden form field on the client.

2) Can the RegisterHiddenField method creates a server hidden field, in
order to make it appears at the trace page?

No. The server side is unawarae of any non-Control HTML in the page.

How can I read the value of the
hidden field correctly in my custom control?

Request.Form("hiddenFormFieldName")

Hi Kevin.

I could successfuly read the contents of the hidden field using the OnInit
event of my custom control when clicking a button for example. But if I
'refresh' the page I loose the value. What is the difference between
refreshing a page and clicking a button? Aren't they both a submit?

TIA,

Hi.

I am creating a custom control that uses the RegisterHiddenField method to
insert a hidden field on a page. When I tried to see the value of the hidden
field on a trace, I noticed that it does not appear on the Control Tree
section of the trace. I put a normal hidden field on an aspx page and set it
to run as a server control, and the control appears at the trace info. I
have two questions about this:

1) Only server controls can appear at the trace page? Is it possible to make
regular html controls appear at the trace page?
2) Can the RegisterHiddenField method creates a server hidden field, in
order to make it appears at the trace page?

Also, I tried to inspect the value of the hidden field using Request.Params
in the OnInit event of my custom control. It always returns me "", though I
change the value of the field in Javascript. How can I read the value of the
hidden field correctly in my custom control?

TIA,
