Keep state on postback

Keep state on postback

I have a wizard in a .Net app, 3.5 framework. In my wizard, I would like to be able to go from step one to step two and not lose the state of the controls that are in step one. Example: If a textbox control is disabled with jQuery, when I go to step two and then go back to step one, I would like the same textbox control to still be disabled. Below is the markup and jquery code.
  2. <div class="row">
  3. <label class="label required">Location of Incident</label>
  4. <asp:CheckBox ID="chkLocationUnknown" Text="Unknown" runat="server" />
  5. </div>
  6. <div id="locationDiv" class="row">
  7. <label class="label required">Address</label>
  8. <div id="addressDiv" class="addressDiv">
  9. <div class="addressDivContent">
  10. <div class="row">
  11. <label class="required">Street Address</label><br />
  12. <asp:TextBox ID="txtIncidentAddress1" CssClass="width325 textField jqcLocationUnknown" runat="server" /><br />
  13. <asp:TextBox ID="txtIncidentAddress2" CssClass="width325 textField jqcLocationUnknown" runat="server" />
  14. </div>
  15. <div class="row" style="vertical-align: top;">
  16. <label style="width: 100px; display: inline-block;" class="required jqcLocationUnknown">City</label>
  17. <label style="width: 100px; display: inline-block;" class="required jqcLocationUnknown">State</label>
  18. <label style="width: 100px; display: inline-block;" class="required jqcLocationUnknown">County</label><br />
  19. <asp:TextBox ID="txtIncidentCity" CssClass="width100 textField jqcLocationUnknown" runat="server" />
  20. <asp:DropDownList ID="ddIncidentStates" DataValueField="value" DataTextField="text" CssClass="width100 textField jqcLocationUnknown" OnDataBound="DropDown_OnDataBound" runat="server" />
  21. <asp:TextBox ID="txtIncidentCounty" CssClass="width100 textField jqcLocationUnknown" runat="server" />
  22. </div>
  23. <div class="row">
  24. <label class="required">Zip Code</label><br />
  25. <asp:TextBox ID="txtIncidentZipCode" CssClass="textField jqcZipCodeMask jqcLocationUnknown" runat="server" />
  26. </div>
  27. </div>
  28. </div>
  29. </div>
