.Net 2.0: Programmatic Container selection

[Graham]

Hi,
I am trying to write a custom email form control that doesn't require
programming experiance in order to implement (for our html guys). I have a
base design that I would like to use for the markup but I am having trouble
getting it working.

<ec:intelleform runat="server" id="intelleform1" SubmitButtonId="FormSubmit"
Macro="$"
SmtpServer="<%$ AppSettings:SMTPServer %>">
<FormTemplate>
Hello
<asp:TextBox ID="YourName" Runat="server"></asp:TextBox><br>
sender <asp:TextBox ID="Sender" Runat="server"></asp:TextBox>
<asp:Button id="FormSubmit" Runat="server" Text="Email
it!"></asp:Button><br>
</FormTemplate>
<EmailTemplates>
<ec:EmailTemplate From="(e-mail address removed)" To="(e-mail address removed)">
<Template>
<strong>Your Name: </strong> <%= YourName.Text %><br />
<strong>His Name: </strong> <%= HisName.Text %><br />
</Template>
</ec:EmailTemplate>
</EmailTemplates>
</ec:intelleform>

<asp:TextBox ID="HisName" Runat="server">John</asp:TextBox>

---
The <formTemplate> is where the email form controls get placed it is an
ITemplate.
Each <ec:EmailTemplate> controls who the email goes to, from and the format
of the email body: <Template>.
The problem I have is when trying to use <%= YourName.Text %> to write out
the Text value of teh YourName textbox I get the run-time error "The name
'YourName' does not exist in the current context"
is there any way around this?
I have noticed if I change the code to <%= (this.FindControl("YourName") as
TextBox).Text %> it works.
I also have no problem with <%= HisName.Text %>< (which isnt in the
FormTemplate).
When I send the email its fine, it can find the references from the code and
renders the body apropriately.
I Instantiate the Itemplates into a temporary PlaceHolder then use
..RenderControl() into a HtmlTextWriter.
I hope this makes sense, I can provide more explantions and code if asked.

Cheers
Graham

Hi Graham,

After reviewing your post, your question is "why cannot directly reference
the control placed inside a template". If I've misunderstood anything,
please feel free to post here.

I suppose you must be using attribute TemplateContainerAttribute to
designate a template container for your template. A template container type
is a simple Web control decorated with the INamingContainer interface.

Only controls put into the Page container can be reference directly using
its ID. For controls placed inside other container, you will have to first
get the reference to the container, then use its FindControl method to find
it.

Hope this helps. Please feel free to post here if anything is unclear.

Sincerely,
Walter Wang ([email protected], remove 'online.')
