OnClientHiding Postback

[Storm]

I would like to do a postback with onClientHiding.... It seems that onClientHiding does fire but the postback is not..

   function OnClientHiding(sender, args) {
        __doPostBack('<%=btnCloseMessage.ClientID %>', 'OnClick');
    }

<asp:UpdatePanel ID="Message" runat="server" ChildrenAsTriggers="True" UpdateMode="Conditional"
    Visible="True">
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="btnCloseMessage" EventName="Click" />
    </Triggers>
    <ContentTemplate>
        <div style="visibility: hidden; height: 1px; width: 1px; overflow: hidden">
            <telerik:RadButton ID="btnCloseMessage" runat="server" OnClick="btnCloseMessage_Click" CausesValidation="False">
            </telerik:RadButton>
        </div>
        <telerik:RadNotification ID="RadNotification1" runat="server" Skin="Black" AutoCloseDelay="0"
            VisibleOnPageLoad="False" Width="300" Animation="Fade" EnableRoundedCorners="true"
            OnClientHiding="OnClientHiding" EnableShadow="true" Title="Breaking News" OffsetX="-20"
            OffsetY="-20">
            <ContentTemplate>
                <asp:Literal ID="litMessage" runat="server"></asp:Literal>
            </ContentTemplate>
        </telerik:RadNotification>
        <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick">
        </asp:Timer>
    </ContentTemplate>
</asp:UpdatePanel>

changing from

__doPostBack(

 

'<%=btnCloseMessage.ClientID %>', '');

To

__doPostBack(

 

'<%=btnCloseMessage.UniqueID %>', '');

Worked

Hello Storm,

Indeed, you have correctly noticed that the call should be done with the UniqueID. In simple scenarios when no INaming Containers are used, ClientID or even simply the ID will work, while when calling it when in INaming Container you should provide the UniqueID so that your control can be recognized as the eventTarget. There is some confusing information on the net regarding that (e.g some say that it depends on the browser what ID to use) but the difference is in the INaming Containers presence on the resultant page and I can assure you that the solution you have found is a reliable one.
