How To Clear All Form Fields From Code-behind

Apr 10, 2010

HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />.

Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ?

Update:

Context is a simple Contact/"Send us a message" page with 8 asp:TextBoxes on the page (where the user enters the name, address, phone, email, message, etc.). Then he clicks on submit, the Onclick message handler in code-behind sends an email to some administrator, and all the form fields the user filled in should be emptied and he gets a notification in a label ("Message sent blabla..."). I want to have the form fields cleared to avoid that the user clicks again on submit and the same message is sent a second time.

How To Clear A Status Message On A Web Form When Starting A Process

Sep 21, 2010

I have a web form used for importing data from a CSV file. It contains a result panel and a result label, which either show a success message or an error message after the import process. Let me say here I know the page should not be doing the import, but this is legacy code and the client expects only small changes.

My problem is that the result message (label) retains it's previous content and visibility during the next import process, because clearing it during Page_Load or at the beginning of the import method only has effect when the import method is complete and thus the postback is complete.

At the moment, the only solution I can see is to move the import code into a separate class (as it should be), call the import method asynchronously, clear the result message, and thne set then result message when the complete or error callback from the import process is called.
