error: marked invalid because it is a mismatched end tag

I shuffled things around and got a well formed page:

line 8 (table opening) cut and replace on line 6 (right after )

line 56 (table ending) cut and replace on line 55 (right after )

this encloses the HeaderTemplate and asp:Repeater within the table tags.

Besides now being a 'well formed' document, I found a considerable increase in forum response.

You'll be shocked but the thing originates in MSDN. It has a lot of examples which contain the error. I think it was originally related to DataGrid etc. style things and was copied everywhere by 'botcoders'.

Interesting..:shock:

Even if there was a malformed table tag it would be unlikely to have a big impact on performance IMO.

IIRC the 'error' is that the table tag should be closed before the headertemplate tag in order to be a well formed html doc.

The browser eventually sorts it out, but making it well formed there's less to think about for the engine.

If you move things around as in my above post, the table encloses the HeaderTemplate and asp:Repeater

fixing it seems to have made the page loads quicker

It doesn't pass HTML validation? Please show me where you see that... All *rendered* pages have been tested again HTML Tidy and validate.

It's within an UpdatePanel, maybe something is related to this, when server-side tags are rendered. But I can't see any differences.

when open in Microsoft expression, those lines are red with a 'squiggly' underline; if you hover the mouse over them, they say the errors I typed (basically that some tag was 'spanning' another tag, and should be enclosed by it). After moving things around as above, the 'error' goes away.

Here's an example from the SDK. Note that the begin and end table tags are inside the repeater control, in the Header and Footer templates.
