First of all: buy an ASP.NET book to read in on the fundamentals.

If you want to hide controls, use:
idSubmit.Visibl e=false;
txtName.Visible =false;

You should use a label control to output your message to the user. The
message may look ok, but the Click event is handled before Page.Render()
causing something like:

Thanks for filling out our survey Doe 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
....
</HTML>

Which is less than perfect.

Don't write to response (although you can if you wish). Rather prepare all
you want to render in design time and manipulate Visible property.

Re: Response.Write( ) ??

ok, thanks.

is there any way you can prevent a control from rendering itself at runtime
(based on a if-condition) ?

Re: Response.Write( ) ??

Yes, of course. Assume that the user queries you page using parameters in
the uri:"testpage.a spx?hideButton= yes"

then you can test this in the Page Load handler:
if(Request["hideButton "]=="yes")
idSubmit.Visibl e=false;

Or a more irrational condition if you want to hide the button at night:
if(DateTime.Now .Hour>20 || DateTime.Now.Ho ur<6)
idSubmit.Visibl e=false;

Re: Response.Write( ) ??

Most of them have a visible and enabled attributes. You can set both of
these to false to hide and disable them. They both have to be set to false
really in order for best performance and for best results.

Hope this helps,

Re: Response.Write( ) ??

apart from setting the visible property to false, is there a way to do that
in the Page-PreRender-event handler ?

some check allowing me to prevent the rendering of a specific control on the
page
thanks
Chris

Re: Response.Write( ) ??

I don't know what you're after, setting Visible to false prevents the
rendering of the control. The metod void Render(HtmlText Writer) for the
control never gets executed. It doesn't matter if you do this in Load or
PreRender, rendering is completely prevented anyway.
