I don't seem to be able to turn viewstate off.
I have created a vb.net asp.net project with two textboxes and a button on the default webform.I have "enableviewstate= false" for the page and for all three controls. I run the form, type something into the textboxes and hit the button.When the form comes back at me, the data I typed is still in the textboxes and when I look at the source it has created the usual hidden contol for the viewstate.
Am I missing something?

You can't remove the saving of state for textboxes. There are a couple of controls that you can't do this for (I forgot exactly which ones, but I believe checkboxes are the other one).
Also you can never completely remove viewstate. If you search around the web you can find a utility that will decode the ViewState into human readable form and you will be able to see what is left in viewstate. One thing that will always be there (this was a problem that I have before and could never get around) is a list of all of the controls which will cause a postback to occur. There is some other information in there as well.
One way you can prove that viewstate is indeed turn off for the textbox is to put something very large into the textbox and hit the button. The size of viewstate should still be small, i.e. not include the large amounts of text that you put in the textbox.
If you want to clear out the textbox then you will need to set the text property of the textbox to an empty string.
