ASP.Net beware the rogue ‘form’ tag!

I have just spent 3 evenings trying to resolve an issue with an ASP.Net datagrid and getting the updated values from the cells in the OnRowUpdating event.After trying every conceivable possible method of getting the values under the sun I find that the cause of these missing values was one ‘form’ tag with ‘method=”post”‘ sitting in the HTML of my master.master page and screwing up the postback

Damn that was a hard lesson to learn!
