title: How to clear check boxes after button click
body: <p>Simply put, I have a series of videos with check boxes in a gridview.  After hitting submit, there is a postback, and they go to another gridview on the same page.  My question is simply this, how do I make the initial check boxes where the user first picks the videos be unchecked?  Every time a user hits the submit button after selecting a few videos the boxes stay checked and if you pick some more and hit enter without realizing the other ones were still checked you now have duplicate entries.</p>
  
  <p>I am sorry for what I estimate is a simple answer, but all the research I have done deals with much more elaborate problems.  </p>
  
  <p>Thanks in advance!</p>
  
  <p>EDIT:  I am sorry, I should have mentioned this is in C# ASP.NET.  This is the check box in question:</p>
  
  <pre><code>&lt;asp:CheckBox ID="cbAdd" runat="server" /&gt; 
  </code></pre>
