Hello all,
I have always been having this issue and wondering what the solution is.
When I set the enableviewstate property to false for a textbox, the textbox
always retains its value after a postback occurs. Why is this? I want the
textbox to become empty after postback. How can I do it without setting
textbox.text = "" and without doing Response.redire ct to the same page.

When you submit a form to a server, the browser always send the field values
(those who are named, not disabled and inside the form) to the server. This
is how a HTML form works "by design".
The "viewstate" is just an hidden field added by ASP.NET to store extra
informations and carry them over accross multiple server side executions of
the same page. It doesn't contains field values.

Yes, the browser always sends the field values to the server. But after the
form is submitted, why does the asp.net textbox retain the text value. It
should be reset to the default value which is blank field. This issue only
with asp.net server controls. If i use <input type="text" name="txtname"
....... then I will not face this problem. I hope you are getting my
question.

Hi JK,
That behavior is by design:

With asp.net you can have "server side validators" , a feature
not present in "old" asp (or jsp, or php, or ..).
When a validator blocks a page, the user gets his/her page
back, complete with all (ok, nearly all: password is an exception)
values and the now-visible validator text.
If the input gets cleared after every postback, your user would need to
retype that input every time the validator blocks submission.
You, as the developer, can decide when the data is safe in the database
and only then clear the form. You could do this by clearing every named
input, or by writing a procedure that loops through all controls on the
page, clearing them in an appropriate manner.

You have mixed up two concepts: ViewState and the value of a field posted
back. The key idea here is that properties directly connected to the form
value will always get the form value assigned on post back.
The TextBox.Text property is updated from Request.Forms on post back. It
reflects the live data. ViewState preserves the last known value of several
properties.
In fact, it preserves the value of the Text property although thats so it
can determine if the OnTextChanged event needs to fire. It needs a "before"
and "after" case to do that.

Even though the Viewstate has been disabled, ASP.NET
still uses about twenty bytes for Viewstate.
Not only can you disable Viewstate at the page level, but
you can also disable Viewstate at the control level. For
example, the following code disables Viewstate for a

I tried to turn off viewstate and so I added enableViewState=false in
side the Page directive, rebuild the page, test it. - not working
Then I set all controls on the page so all their enableViewState is also
false -- still, not working.
After doing al these, I still see the hidden viewstate variable in the
HTML source. Please help!!!!!!!!
Thanks!

I have a page with a few textboxes. When the page is posted, the textfields
retain their values even though I have viewstate turned off. It's turned
off in 2 different places.
- The control itself.
- Page.EnableViewState = false; in page_load.
How do I get the textboxes cleared after a postback without clearning them
programmatically?
