Re-post

I have a validation form that posts to asp.net the program checks the input for errors and advises the user if there are errors. The program works ok except if the user posts the data then refreshes the page the data is re-posted. I have checked and the easiest solution seems to be Response.Redirect back to the original page. That works ok except it clears the users input boxes- any way around that or better method? Posting button:           <asp:Button ID="Button1" runat="server" Text="Click for Function"/> Input Sub:     Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Thanks, Steve
