Preventing AutoPostBack According To Confirmation Dialog
Aug 5, 2010
I want to show a confirmation dialog when a specific value is selected in an asp:DropDownList. If the confirmation dialog returns false (cancel) then I want to prevent the AutoPostBack.
<asp:DropDownList id="theDropDownID" onchange="foo()"></asp:DropDownList>
However, it ignores the returned value from foo() and actually does the postback. The generated code of the onchange event is:
foo();
setTimeout("__doPostBack('theDropDownID','')", 0);
so basically controlling the setTimeout that the .net adds, will do the job.

A user inserts ad details and on button click saves them to database. If the save is successful, a DIV element slides down (becomes visible) allowing the users to add pictures for that ad.
As the users adds the pictures, they are being shown in a Repeater control. When you hover over a picture, a Delete button is displayed and when you click it, a confirmation message pops out asking the users if they really want to delete the picture.
Now this is where the problems begins. The code behind the button click doesn't wait for the user to click YES or NO. It just executes leaving the message displayed.
So to summarize:
- The entire "bottomDIV" element is wrapped inside an UpdatePanel with update mode set to "Conditional".
- Since the Button is inside the Repeater control, I cannot access its Click event. I use Repeaters ItemCommand to check for the correct Command Name.
- The Repeater Control is inside the same UpdatePanel
- The Update Panel has AsyncPostBackTrigger set to Repeater Control.
The HTML:
HTML Code:
<asp:UpdatePanel ID ="bottomUpdate" runat ="server" UpdateMode="Conditional" >
<ContentTemplate>
<div id ="bottomWraper">
<div id ="savePictureWraper" runat ="server" style="float:left; padding-top:3px;" >
<asp:TextBox ID ="pictureName" runat ="server" placeholder ="Naziv slike" style="width:181px;">
[Code] ....
The Script (using alertify.js to display the confirmation dialog):
HTML Code:
<script>
$("[id*=btnDeletePicture]").on("click", function () {
alertify.confirm("Confirm?", function (e) {
if (e) {
alertify.alert("Successful AJAX after OK");
[Code] ....
The code behind is simple and all it does it executes the delete statement and then calls the displayPictures sub again. So, why the code behind doesn't wait for the user to select an option in confirmation dialog....

I need to collect additional information from the user when they initiate a delete on a radgrid. Right now I am presenting the user with a confirmation dialog box that lets them click "OK" to continue but I need to add an additional textbox to collect a reason.

I have JQuery confirmation dialog function that called by server side code (C#)how to get its return value of that function? in this case the return value would be either Yes or No.I called it in button clicked event as below:
Code:
protected void btn1_Click(object sender, EventArgs e)
{
string message = "Message from server side, please select yes or no";
ClientScript.RegisterStartupScript(this.GetType(), "Popup", "ShowConfirmation('" + message + "');", true);
}
my question is how to get JQuery return value, in this case the return value would be Yes or No?
Code:
=== JQuery Confirmation Dialog ==
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.9/jquery-ui.js" type="text/javascript"></script>
<link href="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.9/themes/start/jquery-ui.css"

I am trying to use confirmation dialog from jQuery UI.
I ran into this problem: how to trigger correctly the dialog and at the same time prevent trigger OnClick event specified at button until user click on Yes or No buttons at dialog?
In the example below are two ways how to popup confirmation. Lower one works well. It's a classic JavaScript confirm dialog. When I try to use the jQuery UI dialog, it displays a dialog but allows it to run the event assigned at OnClick (here by using Command, but I suppose there is no difference. Hope I am not wrong.). The piece is taken from the ASP.NET Repeater control btw.

Is there any way to add a confirmation dialog to a submit button when the form already has other validation controls and a summary control using "showmessagebox=true"? I tried adding
OnClientClick="return confirm('Are you sure?');" to the submit button, but that seems to block all of the other validation?

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.

I am using MVC2 on VS2010 Express edition. I followed a post by Dino Esposito on UI with JQuery passing data to a dialog from strongly typed views. I can't make the dialog work with modal:true option.Here I have a simple page that includes RenderPartial for a dialog. The dialog is supposed to pop up when a button is clicked. However, if I include modal:true as one of the dialog options, then when the button is clicked nothing happens. The dialog does not pop up. When I remove modal:true from the dialog options then dialog pops up as expected and closed as expected.

I've got a div on Page A.When an event happens (whatever I define, a click, whatever), I do a div.Dialog, set its properties and open itThe data inside is returned from an async .ajax call that grabs the data from a url and appends it to the div by calling div.html(data) inside the .ajax callback, so it's essentially loading a PageB by getting the data (content) and appending it to the div that's calling the dialog("open")...nothing special here I don't think.
My question: In Page B, how do I reference the dialog so I can do some things to it? For instance in Page B's content that I received back from that .ajax call and added to the div via .html(data), there is a button and when clicked I need to close the dialog.Right now my buttons are not working inside the dialog because one of them closes out the dialog and the other should redirect to a new page but both do not work now because I have no reference to the dialog that it's in to manipulate it. So I need reference so I can close the dialog via some jQuery that will reside in PageB (data).

I'm using the "cache tecnique" to prevent multiple logins. Reading in this forum I have read the following code:
Global.asax
[Code]....
Login.aspx
[Code]...This code works fine, If the user is already logged the second login is not permitted. But....
But if I make the logout (destroing all my session variables) and I try to login a second time... it's not possible, I read that the user is already logged!!I have also tried to clear the cache after the logout but nothing changs, even if it is illogic because the code must work even if I don't do the log off...

there any way where i can make a page only accessible through a RedirectToAction? It's a bit dumb of a question given a redirect writes a URL.. I know it might sound a bit silly, but i really don't like the fact i have to be 'forced' to create a partial view to be able to make the page i want to redirect to. What i want to do is quite simply, after deleting a user account, redirecting to a page where it says, account deleted (with a bunch of other stuff), so its quite a simple task. I have no problem making a partial view here and there, but if i want to make many pages unaccessible, i think i would have to make most of the website in partial views haha. Maybe i'm getting it wrong though, i've read a couple of posts about it, including Phil Haack's ->http://haacked.com/archive/2009/11/18/aspnetmvc2-render-action.aspx But i'm still very confused about this subject,

This involves using the Membership provider to add a comment to users server side records when they log in and out, and then confirming that when a cookie is used to authenticate, that the user hasn't logged out. This makes perfect sense to me. Where this starts to fall apart is that we do not currently use a membership provider, and so it seems like I face reimplementing all our authentication code to use a membership provider. We currently check authentication in a controller, and make a call to FormsAuthentication.SetAuthCookie() once we know the user exists. It would be a lot of work to force a membership provider in.
Is all this work really neccesary. Can I roll my own key value store of cookie values to logged in users and just make sure I clear this when a user hits the logout button. If this seems unsafe is there a way of implementing a minimal Membership provider in order to make these checks without handing off all authentication code to it?
I guess my main problem here is that we decided a long time ago that the membership provider model doesnt fit with the model we use for locking and unlocking accounts, and chose not to use it. Now we find that the MS recommendations specifically mention a membership provider, and as this is security I need to be sure that not using it as they recommend isn't going to cause troubles.

I am relatively new to ASP.NET and have searched the Internet to find guidance in preventing caching of web pages (in the latest versions of IE, Firefox, Chrome and Safari). Based on my search, I found a lot of conflicting/confusing info. As best as I can tell, it appears that I need to add the following 3 lines to the <head> section of my .aspx files:
[Code]....
if the aforementioned lines are correct and if all 3 lines are necessary? I have tried using different combinations of the 3 lines, but I get conflicting results (i.e., sometimes the page is cached and sometimes it's not).

I am developing a registration process which consists of 4 steps. Each step has its own action method. As such a user could type the url for each step as follows: bogusURL/Step1 //returns the View Step1 bogusURL/Step2 //returns the View Step2 etc... I would like to prevent users from gaining access to a step unless they have completed the previous steps. i.e. If they typed in bogusURL/Step2 without having completed Step 1 they should be redirected to the first step.
What is the best way to implement this?

I'm using a file manager-type WebControl that does lots of postbacks. It's placed inside a Page that is relatively complex. I would like to prevent the WebControl from causing the whole Page to go through the lifecycle.
Is there any way to isolate the WebControl from the rest of the Page? The only way I can think of is sticking the WebControl in a separate Page and creating an iframe in the original Page. Unfortunately that also means my WebControl properties/settings are no longer in the original Page. If I want two instances of the WebControl with different settings, then I have to create a Page for each setting and reference the correct one in my iframes. Not quite as "drag & drop" as I would like.
