LoginStatus Inside LoginView Doesn't Trigger LoggingOut Event?

Aug 11, 2010

I have a LoginView in my APS.NET application with AnonymousTemplate and LoggedInTemplate. I've put LoginStatus control inside LoggedInTemplate but it doesn't work as expected.

Here's the code

<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
<asp:Login ID="Login1" runat="server" OnAuthenticate="Login1_Authenticate"
DisplayRememberMe="False" PasswordRecoveryUrl="/"
DestinationPageUrl="/">
</asp:Login>
</AnonymousTemplate>
<LoggedInTemplate>
You are logged in as
<asp:LoginName ID="LoginName1" runat="Server"></asp:LoginName>.
<asp:LoginStatus ID="LoginStatus1" runat="server" LogoutAction="Redirect"
LogoutPageUrl="/" onloggingout="LoginStatus1_LoggingOut" />
</LoggedInTemplate>
</asp:LoginView>

All event handlers are correctly defined in code behind file.

The problem is that if user logs in he will see his user name with logout link from LoginStatus control. Clicking the logout link takes the user back to login form (both login and logout form are part of the same user control) but if I refresh the page the user is still logged in.

I've noticed that if I move LoginStatus control outside the LoginView then logout process works as expected. I've also noticed that when LoginStatus is inside LoginView then it doesn't raise a loggingout event.

UpdatePanel Update Without Trigger Button?

Jan 12, 2011

I have an UpdatePanel with ContentTemplate specified. When page loads, user can do some AJAX work in other part of the page. Then, after that work is finished, I would like to update only content inside UpdatePanel, but without pressing any buttons etc. I should be done automatically using JavaScript when previously started AJAX work finishes. How to do it without manual clicking on the trigger button?

EDIT:

Ok, I've followed that _doPostBack rule, and whole page is posted.

<asp:UpdatePanel ID="panelAttachments" runat="server">
<ContentTemplate>
........
</ContentTemplate>
</asp:UpdatePanel>
<input type="text" name="test" onchange="__doPostBack('<%=panelAttachments.UniqueID %>',''); return false;" />
</td>

Conditionally Trigger A Full Page Postback From A Link Button Inside Update Panel

Nov 29, 2010

How do I conditionally trigger a full page postback from a link button inside of an update panel?

I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.

Here is the control hierarchy:

Page
Custom Control
UpdatePanel
LinkButton

Event handler Pseudo code:

LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
Page.DoFullPostback
End If
End Handler

Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.

AJAX :: How To Trigger Updatepanel Postback From Another Updatepanel

Mar 4, 2011

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.

How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?

AJAX :: How To Mimic Button Click Inside UpdatePanel With JQuery

Mar 7, 2011

I've a dropdown and a listview inside an updatepanel (Master/Child relationship) so based on value selected in dropdown the listview gets populated. The Listview allow user to perform Edit/Insert/delete of records. I have to implement a scenario when a user is editing/inserting a record and if he tries to navigate away/change the value in dropdown he should be prompted to save the data and if he choose yes in JS Confirm Dialogue then the currently edited/inserting record should be saved (for which i'm trying to mimic the click of the update/insert button using js). I've attached change eventhandler of dropdown using JQuery which is getting called properly bind.
[Code]....

This code gets bind using
Sys.Application.add_load(saveChanges);
I also tried the following
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(saveChanges);Sys.WebForms.PageRequestManager.getInstance().add_endRequest(saveChanges). The eventhandler gets called correctly but the click() doesn't work! Also the reason I'm calling click() method of button is to perform the validations via RequireValidator/RangeValidators.

Web Forms :: LinkButton Not Causing Validation Inside UpdatePanel (normal Button Does Though)

Jan 30, 2011

I am using a MultiView inside an UpdatePanel with several views within it and a button on each that is supposed to validate the controls on the current view before moving onto the next view in the sequence (a bit like the Wizard control except I wanted more freedom).

I am using an LinkButton but the problem is that the LinkButton is not causing validation -- I have also tested with an ImageButton which isn't causing validation either. However, when I use a normal Button, the validation does work. I have grouped my validation controls into a ValidationGroup and made sure that CausesValidation is turned on.

AJAX :: Javascript Change-state Toggle Button Inside An Updatepanel?

Oct 7, 2010

I've got a rather difficult one here. I have a JavaScript jquery toggle button inside an update panel. Right now i'm using <form body="onload"> to recall this javascript to re-apply the button state after each partial postback. It works, but it requires two clicks sometimes.

The problem is... after a few clicks, it is significantly slowing down the PC, and I can see the clicks trailing half a second to nearly a second. If I have a group of buttons, all those click events are just catching up to my clicks. It is rather amusing but I suppose it has to do with the fact that the postback is calling the <body onload=" event> each time after the button is clicked.

so how can I then, make this performance faster?

AJAX :: Textbox And Button Inside An Updatepanel In Internet Explorer When Pressing Enter?

Apr 7, 2010

I'm currently building a simple chat application and I have everything working real smooth except for one thing, and this problem is only in IE as far as I know (in firefox there is no problem).

In my chat application I have the textbox where the user writes the messages to the chat and the button that sends this message togheter in an updatepanel (so that there is no visible postback when pressing the button). I also have in the form tag "defaultbutton=" set to the button. The problem is that when the user uses Internet explorer and presses Enter instead of pressing the button with the mouse that after the 2 first times he/she does this causes the textbox to stop focus on it, which it shouldnt do as in the end of the button the code says it should focus, which works the 2 first times for some reason.heres the code where the problem exists:

aspx:

form id="form1" runat="server" defaultbutton="Button1">
<asp:ScriptManager ID="scriptManager" runat="server">
