  AutoPostBack=true does not work when I select a particular Item in Page_Load

  Apr 11, 2012 01:48 PM|LINK

  Hi,

  my question is very simple, I have a RadioButtonList which has all Items disabled in the markup. In Page_Load, I am enabling all of them programmatically and doing rdo.Items[0].Selected = true;, when chooses any other option, it does not do postbacks.

  When I take off the Items[0].Selected = true part, it works fine.

  And yes, I cannot select Items[0] in markup because the stuff has to go through conditions.

  It is inside if (!IsPostBack) { }

  I do not see it posting back, when I click on radio buttons; I do not see any javascript run and refresh the page.

  Here is a simple example with no masterpage, and acting crazy...

  <asp:RadioButtonList ID="test" runat="server" RepeatDirection="Horizontal"
                          AutoPostBack="True"  >
                          <asp:ListItem Selected="True" Text="Test1" Value="1" Enabled="False"></asp:ListItem>
                          <asp:ListItem Selected="False" Text="Test2" Value="2" Enabled="False"></asp:ListItem>
                      </asp:RadioButtonList>

      Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
  
          If Not IsPostBack Then
              test.Items(0).Enabled = True
              test.Items(1).Enabled = True
  
  
              test.Items(1).Selected = True
          End If
  
  
      End Sub

  
  
  

  Microsoft stuff always acts up on me when I have deadlines unfortunately....

  I will put in some jQuery code to do postbacks while I wait for what you guys have for solution to this.

  I thought so....

  Here is the workaround, use jQuery code for post back

  <script type="text/javascript">
          $(document).ready(function () {
              $("input[type=\"radio\"][name*=\"test\"]").change(function () {
                  __doPostBack($(this).attr("name"), '');
              });
          });
  </script>

  
  
  

  MS has the issue report now.
