Web Forms :: Master Page Event Not Firing On Remote Web Server
May 18, 2010
I have a master page with a login box on it. Inside the login box is a button -
[Code]....
NOW ... On my local dev machine this code works fine. The control fires the event and everything is how it should be. When I run this site on a remote web server (tried two of them - both IIS7 running on 2008 R2) the event is never called. I added some logging to see what is happening and the PostBack event on the Master Page does not happen when the button is clicked - the page is just reloaded.
I'm using SelectedIndexChanged on a gridview row to trigger an event which is working fine in a normal webform. But, when I included "master page", it's not triggering the same event.
everything is same except, I added MasterPageFile location & removed FORM tag.
I have a fairly complex web app which has two levels of master page. The top level provides a nav bar constructed from a Menu control across the top of the page. Second level master pages provide menus down the side. It all works well.
On both Menu controls, I need to handle the MenuItemClick event. This works fine on the Menu controls on the second-level master pages. However, the Menu on the top level master does not raise the event at all.
This web site makes extensive use of Ajax and the top-level master page contains the ScriptManager. Before I go to all the work of creating a much simpler test site, why the Menu control is not raising the MenuItemClick event?
Here is the markup for the Menu in the top-level master:
[Code]....
Here is the MenuItemClick event handler:
[Code]....
The logging call in the event handler never gets called. Equivalent code in the Menu on the second-level master does get called.
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 put a break point at the protected void Page_Load(object sender, EventArgs e) method of my master page, but when i start the site it does not hit that break point.
Why is the event not firing? I would like to use this event along with others such as the Init event in order to check to see if the session has expired everytime a page loads...
I have a DetailsView control bound to an ObjectDataSource within a User Control (.ascx). It appears that the DetailsView.OnDataBound event is being fired on every page load or postback.
I do not see this behavior with a similiar DetailsView directly placed on an aspx page.
i have an ASP.NET application that needs to check a database daily and send emails.
I am using cache item expire to do that, on my localhost everything works fine but on my shared hosting server the CacheItemRemovedCallback events doesnt fire.
The code that works on my localhost is :
'test code, set to expire after 1 minute onRemove = New CacheItemRemovedCallback(AddressOf CacheItemRemovedCallback) HttpContext.Current.Cache.Insert(DummyCacheItemKey, "SendEmail", Nothing, DateTime.Now.AddSeconds(60), Cache.NoSlidingExpiration, CacheItemPriority.Normal,onRemove)
Could be something that blocks this code on my shared hosting sever?
now a days i'm working on my project. In project there is a aspx page which is binded with a masterpage, the problem is that when i run the project in debugging mode i found that page load event of a page is firing two times instead of one along with masterpage page's page load event. This is crreating a problem in filling a grid. I searched through the internet for this problem some says that it may happen if u have any image whose src="" or due to some bad HTML's on page .But i've gone through the page it does not contain any image whose src="" .
I am running some custom code in a user control using the <%=Code%> tag. The problem is that the code seems to run before the PreRender event. Is there any way for met to get this code to run after the PreRender event?
I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
Here is the situation, I have a nested master page with set of global filters for reports. When they click the run button in the master I want the content page to process the filter and execute a general function called RunReport on the content page. Each report has its own content page with its own RunReport method. Everything I see online says to use public events with the RaiseEvent call. This was easy to code but it doesn't seem to be firing the event on the content page. How do I know, I have an error message section on the master page which I can send messages to from the content and it is displaying nothing. I also put a break point in the content page method and it never hit it. NOTE: MyPortal is a class that contains to variables call Master, which reference the main master page, and Validations which references the nested master page. The page does not throw any errors, it just refreshes like a normal button click. I have traced code to make sure it gets to the RaiseEvent call and when I tried to step into the code it skipped over the line. Here is some code for the nested master page:
I have a page with in a master page. This page has a user control with a text box and a button. I also have another button on the page. As the page first loads the button_click event on both the controls does not fire when clicking the buttons. I also have an event on the enter key on the text box. This event fires which causes a post back. After post back now my button_click event fire. The button_click event does not fire on the first page_load.
I have a masterPage on that i am using AjaxModalPopup for login purpose.My requirement is when i login via Master page then it should show the Logged-in User details on the current Content Page that is using same master page.
Here i am using following code to get it back to the same content page after succesful login but it does not show the user details on the same content page rather when i go to next page then it appears.
I have a master page with a menu on it. I have found now two pages out of dozens where for some reason the master page events aren't firing. I've put a break point in there and it never hits it. Is there something that could cause a disconnect between the page and the master page events? Really weird it happens in Chrome and IE but they fire correctly in Safari.
Here is my situation: I have a user control that has a menu in it. This user control sits on my master page. It is my main navigation menu for my application. I am having an issue where, on one of my pages, users seem to be leaving the page before committing all changes to the database, which results in a loss of data. So what I want to accomplish is - if the user is leaving this page and the data has not been saved yet, I want to prompt the user and say something like "The information is not yet saved, are you sure you want to leave this page" in a modal popup. So my approach is this: In my menu user control, create an event handler called MenuClicked that is raised when the menu web control's (in the user control) MenuItemClicked is raised, I raise my custom MenuClicked event. Then on my master page, I can catch this event in NavMenu_MenuClicked. My problem is - I need to catch this event in my content page, not the master? Am I approaching this correctly?
Can I modify the properties of a content page control from an event fired from the master page?create a delegate and event on master page wire up the master page in the content page create the event handler (function) on the content page modify for example:
contents of the Text property of a textbox render a control visible (or hidden) etc...
I have a master page with a DropDownList. I want to respond to an event from the DropDownList in the code behind of the content page. How would I look for events from the master page in the content page?
I have two asp.net buttons in my page.If i make button cause validation false then am able to fire button click event on server side but not able to validate text box values(but i need to validate text boxes) using required field validator.
