View 2 RepliesIs there a simple way to clear the value of server controls on postback? I have tried ViewState.clear() and it doesn't do anything. The page I am working on inherits from a Masterpage that has viewstate enabled.
View 3 RepliesHTML 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.
I have a contact form inside of an update panel so I don't get the page flicker. Once the form passes validation and the email sends, how do I automatically clear the text boxes?
Here is my C# code:

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.

I have couple of DDL's, namely DDL1 and DDL2. The latter is dependent on the DDL1, which is creating some problem for me. When I choose a value in DDL1 it populates DDL2 accordingly but when I choose a different value in DDL1 it still shows the result from my previous selection in DDL2.
How do I remove historical values from DDL2 and only shows values matching to what is selected in DDL1.
