ControlBuilders and Templates

[Geoff Taylor]

Hi,

OK, so no-one can answer the question below. That's OK, it's pretty
complicated. But can anyone point me at a mailing list or newsgroup
that might be able to answer or help?

Cheers,

Geoff

Hi,

How do I run a ControlBuilder inside a template?

Say I have a tag derived from DataList. I want to be able to use the
ControlBuilder to allow the page developer to use special tags. For
example:

<opgeek:Tasks runat="server" ...>
<ItemTemplate>
<TaskLink><Title/><TaskLink>
<br />
Due: <b><DueDate/></b>
</ItemTemplate>
</opgeek:Tasks>

I can happily use a ControlBuilder to interpret TaskLink, Title, etc. if
they're inside a control of mine (I just set the
ControlBuilderAttribute). But I can't figure out how to do it if the
tags are within a template such as ItemTemplate.

Any ideas?

Geoff

hi Greoff, its very simple actually, look at the last example on this link.

Hi,

thanks for that, but the default use of the ControlBuilder won't quite
do what I want. The problem is that the inner content I want to apply
the ControlBuilder to isn't a direct child of my control - it's inside
an ItemTemplate.

So, in the code:

<opgeek:Tasks runat="server" ...>
<TaskLink><Title/><TaskLink>
<br />
Due: <b><DueDate/></b>
</opgeek:Tasks>

TaskLink could be intercepted and mapped by a ControlBuilder just fine.
But in the code:

<opgeek:Tasks runat="server" ...>
<ItemTemplate>
<TaskLink><Title/><TaskLink>
<br />
Due: <b><DueDate/></b>
</ItemTemplate>
</opgeek:Tasks>

TaskLink is never passed to my ControlBuilder here, because it's inside
the ItemTemplate.

Thanks anyway,

Geoff
