title: ComboBox and EnableViewState="false"
body: <p>Note: I am fairly new with <code>ASP.NET</code></p>
  
  <p>I have a form with two <code>ComboBoxes</code> and one <code>ASP.NET CheckBox</code> list.</p>
  
  <p>I am running into issues outlined as follows: </p>
  
  <p>Though the query was accurate(confirmed by setting breakpoints and hovering over the query and everything step by step) the second ComboBox would not filter by the selected value of the first dropdown. I was then advised to set <code>EnableViewState</code> to false, which I did.</p>
  
  <p>It all worked very nicely, the first <code>ComboBox</code> filtered the second one and the second <code>ComboBox</code> populated the Asp list. The issue now is that the checkboxes selected by the user in the asp list are being deselected after a postback. </p>
  
  <p>When I set <code>EnableViewState</code> to true the checkboxes just refresh, but the second <code>ComboBox</code> does not filter. </p>
  
  <p>Any ideas on what might resolve this issue?</p>
  
  <p>Thank you so  much in advance!</p>
