Web Forms :: Detect A Pages !IsPostBack In Its User Control?
Aug 4, 2010
I have a page that uses a user control, I have to detect the pages !IsPostBack in the User Control and do some operation
In the User controls page Load method I tried using the following variations to detect the first load
!Page.IsPostBack
!Page.IsCallback
!this.IsPostBack
!this.IsCallback
!this.Parent.Page.IsPostBack
!this.Parent.Page.IsCallback
None of these worked, they all fail to detect the parent pages 1st load in the usercontrols page load method
I also tried using
if (Request.UrlReferrer.AbsolutePath.ToString() != "/PreviosPage.aspx")
This worked for Fire Fox and Chrome but not IE (IE has issues with Request.UrlReferrer, it throws a null exception)
So I cant use this approach as well.

I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page
and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?

What is the best sequence order for Page.IsPostBack and User.Identity.IsAuthenticated? From what I have search for, this comes up most common:
If Not Page.IsPostBack Then
If User.Identity.IsAuthenticated Then
~Some kind of code~
End If
End If
Is this considered "best practice" or can the two items - Page.IsPostBack and User.Identity.IsAuthenticated -be split into their own sections so the fuctions of these can be independent of each other?I am trying to troubleshoot a placeholder that disappears from a master page when a content page button is pressed to change the content pages active view (I have a multiview w/ 5 views inside of it).

I want to display a menu (which will be strongly typed with it's own unique model) across all pages only if a user is logged in.What menu items are available depend on the user's role and also I'll need to hit the repository to get numbers like "x Messages", etc
Been scratching my head for a simple solution here. Don't want to create something that need changes all over the place.All my controllers derive from a BaseController, all my Models from BaseViewModel....probably where I'll be implementing functionality for this.

I have a user control which is used by several pages on my site. I would like the state of the controls within this user control to persist as I move from page to page, but presently any such page navigation causes the user control to reload from it's original state.
I have also noticed that this problem extends to the event handling methods of the controls on the user control. After executing the event handling method in the code behind file the page refreshes and the user control is reloaded from it's original state.
Is there a way to prevent this user control from reloading it's original state?

I have a simple user control(.ascx) with a asp label inside of it. Using the codebehind(C#) from a aspx page, how can I change the text of that label? I have tried using public classes in my user control and a few other things that I could think of off the top of my head. Can somebody give me a quick example of how this would be done?

I'm working on an ASP.net application.I had a problem with a user control I'd designed called LocationSelector. It worked great, but I couldn't use it within an ASP:UpdatePanel. I learned, by browsing SO, that I needed to put my in-line javascript in an external file and register it with ScriptManager so that there are no Response.Write calls in the Javascript.Next, I discovered that the control worked at first, but when I enclosed it within the ASP:UpdatePanel, it would stop functioning after the first AJAX postback. I read that to fix that, I needed to replace my $(document).ready call with function pageLoad() which is automatically executed with each ASP.net page load.
Several of my pages in my ASP.net application work fine (and I was really impressed with how well the framework seemed to drive the application). However, to my dismay, I discovered that my LocationSelector control no longer works at all on three of my pages. The HTML renders, but the pageLoad (which uses jQuery to bind events on control elements) does not fire.I verified this but putting alert('pageLoad'); as the first line of my pageLoad function. On the pages that work, I see the alert. On the pages that don't work, I never see the alert, even on the initial page load.What kind of problem could be causing the pageLoad function on my user control LocationSelector to execute on some pages, but not others?

Is there a way to determine which control on a page caused a post back? I need to be able to make the determination since the _DataBound event of a FormView that I'm working with needs function differently based on which control caused the postback.

We have a SSO solution with ADFS for logging into our web app, we also have standard setup that uses authentication with our database. I want to setup a solution that allows for both. So now I am trying to figure out, is there any way for ASP.NET to detect if a user is authenticated with Active Directory so I could do this on the fly? If user is logged in through AD, send through ADFS, else, show login screen. I also realize that this may not work if they are setup to use forms based authentication only after the ADFS process is started.

This is my approach : I reserve last time that a user post a postback to server in a session and in every postback subtract this value from current value. Is there a better way for this?

I am developing an ASP.NET web application that incorporates google maps. I have an ASP.NET listbox on my page which contains a list of items. When the user selects one of the items, I'd like to show this item on the map. The main complication lies in the fact that google maps uses javascript to control it and the listbox is a server control.
I can think of two ways to do this. The first would involve the listbox calling a javascript function when the user selects a new item. I can then write this function to perform the necessary map operations. Unfortunately, the OnSelectedIndexChanged property of the listbox doesn't seem to support javascript functions.
The second involves wrapping an UpdatePanel around the listbox and getting the listbox to perform a postback. In the SelectedIndexChanged event in VB/C#, I would the need to somehow make a call to a javascript function which would then update the map.

Two users using the same machine, same browser.
User 1 logs in the domain.
User 1 changes some data without saving it.
User 2 logs in the domain in a separate tab.
User 1 switches back to his tab and saves the data.
User 1 actually saved the data into User 2!!
This is caused by the following mechanism:
Different tabs in the same browser seems to share the same session id. We are storing user auth in cookie and the cookie is shared between tabs (same domain)
Therefore, when User 1 request to save, it is recognized as User 2 since the cookie has been updated to User 2.
So I'm wondering if there's any other methods to prevent this from happening, other than:
1. Use cookieless session so the session is embedded in uri.
2. Always include a hidden field in page to indicate which user owns the page.

I dynamically add the webcontrol in onInit or onload (page_load). it will cause the second post back and with the ispostback==false;
if first enter the page is no problem. but if I click on the some button. it will trigger postback two times.
first time: ispostback = true.
second time: ispostback = false.
the second time postback caused me headache because all my value has been initialized due to the coding like below:
DataTable _temp;
if(! ispostback)
[Code]....

I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
