How do I create a new event in a base page class that fires after all derived pages have fired their load events but before any controls fire their load events.
The following code fires the event before the derived page's load event. I want it to fire the event after the derived page's load event but before all control load events:
Public Event FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then RaiseEvent FirstLoad(sender, e) End If End Sub
Private Sub Page_FirstLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.FirstLoad 'Stuff here happens before controls load but only on first page loads' End Sub
On page load is there a way to enumerate all the nest user controls for that specific page load?
I'd like to be able to enumerate all the user controls that implement an interface, and call the interface method for the controls before asp.net passes control to thier page_load events.
The problem is from the master page level, any page in the app could be loading, and each of them could have any random user control, and I need the type reference to determine if they implement the interface, and to call the method.
How do i call the OnLoadFun method so the i is being called onload time. i tried putting window.onload=OnLoadFun surrounded by script tag within the PlaceHolderMain content section.
I have a page with features supplied from both a master page and a child master page.In the content placeholder for the head in both master pages I have supplied the link to the stylesheet for the site.In Design View in VS 2008 the CSS code seems to be functioning correctly.When viewing in a browser the CSS does not appear to be applied at all.
Here is the CSS code for the div elements within the main content placeholder:
Can I load an image into the master page based upon which content page in loaded? For example, site theme "animals", 3 content pages (bird.aspx, cat.aspx, and dog.aspx), when any one of these pages are loaded, I want an image to be loaded and displayed based on that page's name. Is the loading accomplised in the master page ot content pages' on load event?I am working in C#
I am using forms authentication, and a session object to hold user information once the user is authenticated.
I am able to login and log out. I am able to log in and use the "remember me" functionality of the forms authentication.
When attempting to test the "remember me" functionality, the master page load event contains code to check the forms authentication & remember me, and retrieve user info from the database to automatically log the user in. This fires correctly, and the screens all load with the user successfuly logged in, and the users info is successfully stored in a session object.
Without touching anything on the screen, a moment passes and then the master page load event spontaneously fires again, Page.User.Identity.Name still contains the user name, however the session variable is now null, and throws an error.If I tell it to run past this error, it does, and the application continues to function normally, withthe session variables set correctly.
Its almost as if that second firing is ina different session, or something.
I have no problem posting code, but I have a profile class holding / handling the session communication, etc so it is a bit cumbersome.
I have the following placeholder in my main master page. I would like to not have to duplicate my news content in several content pages, so I choose to simply not provide this content in them, and the master page should provide its default.
I'm prototyping an environment where multiple applications run on the same server, but they all share a master page. Is it possible to load a master page from another application? In one of my applications, I have this code:
What this does is set the master page to a file sitting outside my current application. (Note the ".." after the tilde -- so I'm going to the root of my current app, then stepping up a directory to find a master page.)
ASP is displeased with this:
The virtual path '/MasterPages/Root.master' maps to another application, which is not allowed. I understand that it might be stressed out about the fact that there's no backing class for it, but what if I have nothing in the code-behind, and I choose not to inherit my master page from anything -- so the entire thing is contained in the ".master" file?Is there any way to do this?
My asp.net web app uses a master page which contains an 8k jpg of the company logo. Whenever I load a page or do a refresh, all of the non-master page html renders first, then the master page logo is shown, pushing all the html down a few lines. It's very annoying. Is there anything I can do to prevent that from happening?
I used a submit button. when I enter the logon details, full name should be displayed on master page. I could display the full name only when i refresh the browser. can you say hao to get rid of this event
I want to add a class and initialize a JS funcion behind my nested masterpage which is being dervised from an other master page. But when I add the following code in the PageLoade event in the code behined of my derived page then it give the folowing error
System.NullReferenceException: Object reference not set to an instance of an object.
