Very simple viewstate question

[Sahil Malik]

In VS2003 - add a page.
Add a button
Add a textbox.

Set EnableViewState = False for all 3 above.

Put some code behind on Button (anything).

Run the sample - type something in the textbox - hit the button - ..
viewstate is false .. the textbox after postback should contain nothing ..!!

Unfortunately the value of the textbox remains .. What is going on??

Textboxes maintain their state without viewstate. That's because they don't
need viewstate to be persistant - their values are automatically submitted
via the form. You might think the same is true for a dropdown, but only the
selected value is passed in the form which is why disabling viewstate for it
(or other controls) makes the value disapear.

you'll need to manually set it to ""

Textbox's along with some other server controls maintain their state by
default. Viewstate is not the reason for it. These server controls implement
IPostBackDataHandler interface. Thats the reason how they are able to
persist the data. There was a similar thread started yesterday on the
asp.net forums.
