Hello,

If I have a control in the header template of a repeater, how do I get
at this in code? I know how to do this for an ItemTemplate, you just
do...

txtFred = (TextBox)rptNpVars.Items[i].FindControl("txtFred");

where i is the index of the item. How do I do a similar thing for the
header? Following a post I found in the archives, I tried ...

txtFred = (TextBox)rptNpVars.Controls[0].FindControl("txtFred");

but this gave an error "Specified argument was out of the range of valid
values. Parameter name: index".

Thanks for any help.

Have you tried the QuickWatch window on rptNpVars.Controls and seeing
what's in it? I dont know the index for the header template but I would
think it's 0 like you indicated, but see whats in rptNpVars.Controls[0]
by stepping into it in the watch window.

I'm not sure, but I think this index is -1. Just try :)

Another way is to use:

void R1_ItemDataBound(Object Sender, RepeaterItemEventArgs e) {
if (e.Item.ItemType == ListItemType.Header) {

// txtFred = ((TextBox)e.Item.FindControl("txtFred")).Text;
}
}

OK, I'll give it a go (on my way to bed, so I'm not trying it now!!).

Which is fine inside the event, but what if you want to get at it
outside of that? In truth, I suspect that you wouldn't want it inside
the repeater then, but it's too late for my little brain to think this
through!!

Thanks for the reply.

I'm not using VS, so I can't do this. I'm fairly new at ASP.NET and
didn't fancy spending all that money on VS 2003, when it's about to be
superseded by an apparently superior product.

Also, I find I learn what's going on a lot better by doing it all by
hand. I get to see what is needed first hand, rather than having an IDE
make changes without me knowing. I think I've learnt a lot more this way
than I would have with VS.

Thanks anyway.
