I have the following code with the basic required elements to produce the problem:
1<body>2<form id="form1" runat="server">3<asp:ScriptManager ID="ScriptManager1" runat="server" />4<div>5<asp:UpdatePanel ID="UpdatePanel1" runat="server">6<ContentTemplate>7<ajaxToolkit:PopupControlExtender ID="PopupExtender" runat="server" TargetControlID="lbTest"8Position="Right" PopupControlID="buttonPanel">9</ajaxToolkit:PopupControlExtender>10<asp:ListBox ID="lbTest" runat="server" Width="154px"></asp:ListBox>11</ContentTemplate>12<Triggers>13<asp:AsyncPostBackTrigger ControlID="btnAddItem" EventName="Click" />14</Triggers>15</asp:UpdatePanel>16<br />17<asp:Panel runat="server" ID="buttonPanel">18<asp:Button ID="btnAddItem" runat="server" OnClick="btnAddItem_Click" Text="Button" />19</asp:Panel>20</div>21</form>22</body>
The click event is never fired, though the postback occurs.
Any thoughts? Am I doing something "illegal" with the arrangement here? I have a whole form I want to show only in certain circumstances, the results of which should trigger the event to update the main page. How would I do this with Atlas if the given arrangement doesn't work?
TIA, Jeff.
Jeff,
This problem occurs because the PopupControlBehavior's _onClick method calls e.stopPropagation(). That prevents the WebForms.PageRequestManager._onFormElementClick method from getting called. That prevents the asynch postback information from being created correctly. That prevents the asynch postback from working properly.
I believe Ted added the problematic call a long time ago to improve the UI of the PopupControl. I've just pointed him to this thread for more info...
