  ModalPopupExtender shows after AutoPostBack

  Feb 16, 2012 06:03 PM|LINK

  Hey everyone,

       I have a place on my page where a user can select from a radiobuttonlist.  The AutoPostBack = True for the list.

  If the user makes a certain selection I display a Panel that allows them to choose something from a drop-down menu, and press "Select" which closes the popup.

  However, there are other controls in my code that have AutoPostBack = "True" and if the RadioButton corresponding with the PopupExtender is still clicked it will display the ModalPopupExtender Panel again.  

  Does anyone know how I can work around this?  Here is the markup code first, followed by the VB.Net code after.

  <asp:Panel runat="server">
                      <asp:RadioButtonList ID="radInqRel" runat="server" RepeatColumns="2"
                          Width="500px" CssClass="style66" AutoPostBack="True">
                          <asp:ListItem>a. Patient - Self</asp:ListItem>
                          <asp:ListItem>b. Family / Friend</asp:ListItem>
                          <asp:ListItem>c. Clinician, McLean</asp:ListItem>
                          <asp:ListItem>d. Clinician, outside McLean</asp:ListItem>
                          <asp:ListItem>e. Other (e.g. Court, lawyer)</asp:ListItem>
                      </asp:RadioButtonList>
                  <asp:HiddenField ID="HiddenField1" runat="server" />
              </asp:Panel>
              <asp:Panel runat="server" ID="pnlSelDeg" Width="200px">
              <span class="PopupTitle">Select Degree:</span><br />
                  <asp:DropDownList ID="ddClinDegree" runat="server">
                          <asp:ListItem>MD</asp:ListItem>
                          <asp:ListItem>PhD</asp:ListItem>
                          <asp:ListItem>LICSW</asp:ListItem>
                          <asp:ListItem>Other</asp:ListItem>
                      </asp:DropDownList><br />
                  <asp:Button runat="server" ID="btnSelDeg" Text="Select Degree" />
                  <p class="style68">Please Select Degree, page is inactive until degree is selected.</p>
              </asp:Panel>
                      <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server"
                          DynamicServicePath="" Enabled="True" OkControlID="btnSelDeg"
                          PopupControlID="pnlSelDeg" TargetControlID="HiddenField1">
                      </asp:ModalPopupExtender>

  For the RadioButtonList Selection;

      Protected Sub radInqRel_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles radInqRel.SelectedIndexChanged
          If Request.QueryString("prog") = "Hill Center" And radInqRel.SelectedIndex = 0 Then
              SubName.Text = InqName.Text
          End If
          If radInqRel.SelectedIndex = 3 And Not IsPostBack Then
              ModalPopupExtender1.Show()
          ElseIf radInqRel.SelectedIndex = 2 Then
              MoreInfo.Visible = False
          End If
      End Sub
  

  I thought that by adding the And Not IsPostBack would work, but it didnt.  Any help would be appreciated. Thanks in Advance, NickG

  Firstly I see you are missing the Selected IndexChcnged for the RadioButtonList. It is defined in the code behind but it is not associated with your RadioButtonList control..

  <asp:RadioButtonList ID="radInqRel" runat="server" RepeatColumns="2"
                          Width="500px" CssClass="style66" AutoPostBack="True">

   <asp:RadioButtonList ID="radInqRel" OnSelectedIndexChanged="radInqRel_SelectedIndexChanged" runat="server" RepeatColumns="2" Width="500px" CssClass="style66" AutoPostBack="True" >

  If this does not work then  try removing the HiddenField from inside the panel and paste it outside the panel.

  Second remove the IsPostBack condition as it makes no sense

   If radInqRel.SelectedIndex = 3  Then
              ModalPopupExtender1.Show()

  See if this works..

  That worked, also I didn't realize but I had functionality in the Page_Load, which wasn't checking if things were a postback.  Thank you for your help, and helping me realize another thing to check on with the associations of the back-end code.  I appreciate it.
