Steven,

Thanks for the reply. As a followup, is there a way to ensure that this
common html code we are adding is always rendered at the bottom of the page -
ie, just before the </form> tag.

Thanks.

Hi Stech,

Welcome to MSDN newsgroup.
I think your question is such a good one that I really never noticed it
before. As far as I know, there hasn't any good means to accomplish such a
"singleton Html section" task since we are injecting the html block in a
custom webcontrol. And I think your suggestion on using the Page's
Context.Items to store a flag is a good idea. In addition, we may also use
some tricks such as add a control in the Page's Controls collection as
flag , for example:

protected override void Render(HtmlTextWriter output)
{

Label ctrl = Page.FindControl("my_flag_control") as Label;

if(ctrl == null)
{
output.Write("<br>Shared Html!");
ctrl = new Label();
ctrl.ID = "my_flag_control";
Page.Controls.Add(ctrl);
}

output.Write("<br>Main Control Content!");

}

But I still prefer the using Context one you mentioned since it's more
reliable.

Thanks,

Hi Stech,

Thanks for your followup. And as for ensuring a html code is at the bottom
of the <form> section, it seems also not vaiablable in the current ASP.NET
page model implementation(at least at custom control level). Since the
custom control and only access limited part of its container page, and
there is no buidlin properties or method(like the registerScriptBlock for
script section), we can't do it in custom control's code. In addition, I
think ensuring shared html at the bottom of <form> tag seems impossbile (at
custom control's code) because there may exists multiple custom
controls(some other 3rd party ones) each of them want to register such a
block at the bottom of the form, then only one can do that. Do you think so?
