When we double click to page It creates an empty Page_Load event codeblock automatically. Or you know can create other control's event subroutine events by clicking the relevant event in properties window.
but how can we create a Page_Init ? is there an automatic way ? or should we just write its name and parametes manually is the only way ?
I m trying to load a new tab which should load WebUserControl2.ascx on button_clickbut I m coming across this eror: A Zone can only be added to the Page in or before the Page_Init event.I have a webpart in WebUserControl2.ascx which should load FeaturedControl.ascx.Well, i m getting the error when i click on button at :
Private Sub LoadTab2()
Dim uc2 As UserControl = CType(LoadControl("WebUserControl2.ascx"), UserControl)
tp2.HeaderText = "Tab2"
tc1.Tabs.Add(tp2)
tp2.Controls.Add(uc2)
End Sub
Where, tc is tabcontainer, tp is tab panel.
I'm creating a page that users can upload a file to the webserver. After upload the page will then have a link to the file that has just been uploaded, along with any other files that have already been uploaded.As I am programatcially creating links to the files which have been uploaded, I have to do this in page_init or else the link button won't fire off it's event when clicked. MY web page does all this - it creates the link buttons and when I click on them, it calls the event method required i.e. a sub to download the file.
OK, the problem I've come accross is: when I click upload (to upload the file) - the page_init sub is called, displaying all the previously uploaded files as link buttons. Then my btnUpload_click sub is called, which uploads my current file. The only prob is the current file hasn't been displayed? I can only display links in the page_init, but because btnUpload is called after the page_init, the current file isn't uploaded until after page_init and therefore not dislayed?
I have menu item on my master page that has block around the text when the page is first run. I wrote in the css on the link and visited property to change the color to match the image color that it is on. When a menu item is clicked the color changes to the right color. How do I get it to the right color on when the page first opens or is there a way to get rid of the block or make it transperant?
View 1 RepliesI want to add event handlers programmatically to the server controls rather than using their predefined OnClick properties, etc. But which would be considered a better practice for defining handlers:
Define them in Page_Init
Define them in Page_Load
Every time I create a new aspx page and add some new photos and text, after I finish, I have to update page title, Web.sitemap, Sitemap.xml to feed search engines, static sitemap.aspx page, add photos to proper folders, update database to display feeds etc, and I have to remember to upload all new files including links to any new pdfs....This routine eats my time and drives me crazy.
I was wondering if there is such interface, where you need to create only 1 aspx page, for example "Articles" which can populate Texts, photos etc into pre-defined sections, but at the same time it displays with different URL's, so there is a permanent link to it. After you finish it creates a title automatically, based on article title, populates Web.sitemap - does all the dirty work. Similar to how blog engines, Joomla and Drupal work.
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:
Base Class:
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
Derived Class:
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

View 4 RepliesI do some dynamic stuff with UpdatePanel controls and it would be great to store stuff in a Session key and be able to grab it immediately with confidence in a Page_Init. Fantasy e.g.,
If(!isPostBack)
Session[pageInstanceID + "ThekeyIWantAccessTo"] = "123";
else
locVarValue = Session[pageInstanceID + "ThekeyIWantAccessTo"] +"";
I want something like this so that even if an individual user has two or more instances of that page open I am able to respond correctly to the immediate instance in Page_Init. Is it possible to achieve what I want or some facsimile of same? I know I can speculatively make an assumption and then check it in Page_Load when I have access to ViewState, but I would like something that approaches a best practice.

View 1 RepliesI was wondering, if I create a page e.g. index.aspx and I create it's contents based on a variable, would an AdSense block always show the same ad? Meaning is there a way to give it a dynamic content and having the ad addept to the content without creating a page for each content.For example I have a site with 3 links: pears, apples and lemons. I have a database which has the content of each page. I have a dynamic page index.aspx which modifies it's content based on the clicked link (the link always returns to index.aspx). If I want an ad to match my content, should I then do it differently? Like creating pages for each link and adding the content to each page dynamicly based on the link or something?
View 1 RepliesI'm having trouble with an image button I create via c# in an event causing page validation to occur on postback. The CausesValidation attribute is set to false at time of creation in the event. I also wire up the Click event in the page_init with postback so not to loose the event handler if the page posts another way. Here is the code I'm using in the click event of a Button. I've also tried to enable and disable viewstate for the button with no luck. What am I missing here that continues to fire page validation in the Click of this imagebutton?

View 4 RepliesI have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.
So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place?
