How to Handle Refresh Problem (Viewstate)

[VIJAY KUMAR]

I have a problem with Refresh button when user add a new record.

Sample Code:

Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnAdd.Click
lblMesaage.Text = "First Name : " + txtFName.Text + " ,Lat Name : "
+ txtLName.Text
txtFName.Text = Nothing
txtLName.Text = Nothing
End Sub

Explanation:

I am using the same form (Multiple Submission) to add values into the
database. The above code which I had paste is similar to my Problem.

When user Enter his/her first name and Last Name in the specified fileds and
Clicks the add button. This values are added to database(here i am showing on
Label Text ). This text filed values are stored in viewstate too(I need to
maintain viewstate for validations).After adding the values to Database, I am
Clearing the values from the text boxes and postback to the same page.

When user Clicks on Add button agian, its working normal. But when user
Press on Refresh button, the same record which was inserted last time is
inserting again even i cleared the textboxes values.

I want to Clear the values in the view state once I inserted into database
or is there any methods to handle the Refresh Button?

Please Help me...... I hope I am Clear to You.....
