Is there a more general descripton of the sequence of events for a page loading
[Code]....
I am using a master page with a treeview control. I have 2 other pages Summary.aspx and Home.aspx
I want the Summary page to be loaded when I run the application but afterwards I want to load the Home.aspx page based on the selected Node change event of the treeview control.
I have placed the treeview control in master page because it has to remian the same for all my pages.
Did I do something wrong? The problem is I am not able to load the pages based on events occuring for Tree view control.
which is better approach from performance point of view, is it better to use one web-service method to load data by passing Database Table name and keys or is it better to use separate method for each database table! knowing that i'm using .net asmx through ajax requests.it's obvious that one method is better from OO perspective since it have one function type 'data loading' but what about performance? does IIS affected by that or not? also is it better to make multi web-services 'asmx files' or just one!
View 3 RepliesI have a web app that presents a list of statements pulled from the db to be ranked from "Never" to "Always" using a radioButtonList.
Some of the assessments have up to 100 statements, so I'm thinking that a ListView with paging and a RequiredFieldValidator for the radioButtonList would keep the presentation manageable.
I would like to submit the data after all of the pages are complete but I think that would require customization, or is my approach wrong?
what are the events fired during gridview loading,,,,,,,,,,?
View 1 RepliesI've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
View 4 RepliesIn my ASP.Net application, I am using ajax accordian control on my aspx page and vb.net for code behind pages.
I have used validation summary for page validation.
1st accordian Pane contains following fields:
First Name
Last Name etc.
2nd accordian Pane contain following fields:
Address
City
Country etc.
while validating the page It displays error messages in following sequence:
Address cannot be blank
City cannot be blank
Country.....
First Name....
Last Name....
But I want to display error messages in following order:
First Name cannot be blank
Last Name....
Address cannot be blank
City cannot be blank
Country.....
I tried to resolve it by giving tabIndex to textboxes and RequiredFieldValidator, but sequence doesn't change I created RequiredFieldValidator again in sequence, but it doesn't affect.
I want to share a common page load and page init events sequence between Master page and child page and User Control as described below:
Let us have the following components:-
1. TestMaster.master -> It is the master page
2. TestChild.aspx -> It is the Child page
3. TestUserContrl.ascx -> It is the UserControl present within the TestMaster.master page.

View 3 RepliesWhat 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).
We have installed a web site written by others which is compiled with Visual Studio 2008 and hosted in Windows server 2008 R2.
The IIS connection timeout is set to 120 seconds. But for some pages, the first page loading fails with HTTP 404 error but sequential refresh can bring the page up. The same problem happens for some images which fail to load in web pages. We are not very sure it is network related issue or hosting issue.
When master page event fires, content page events are fired first,
is there any content page event that fires after the master page events.
I'm looking for a good tutorial/article that explains the exact sequence of events that takes place when a page is created. I can never remember the order. I think it's something like the parent controls Init event is called, then the child controls Init event is called, in order of the placement on the page. Also, when the control events are called, what order are they called in? For example, if a button event is raised, does this event get called before a DataList_ItemDataBound event is called if the DataList.DataBind is in the Page_Load event? So, does anyone want to try to explain or direct me to a nice article that explains all this?
View 3 RepliesI have update panel on the page to avoid postback and placed a dropdownlist control within that update panel. DrodownList is filled with Category names and also it's autopostback set to True.
Now whenever dropdownlist index change's on select, untill page loads complete data it should show mesage as "Loading.... in center and middle of the page and background should become bit transparent". And when page load completely with data then that background and message should get disappear.
I want to display a loading animation while my page is loading, and when loading is complete then obviously hide it.
I am working in ASP.NET using Masterpages, just wondering there is a a simple way of doing this using JQuery?
I have a previously working ASPX website which also supports AJAX. However, we just upgraded our SQL Server from 2008 Evaluation to 2008 R2 version 10.50.16 and now this website is no longer working. I believe the problem is that now we need to again restore original SQL accounts and settings prior to this upgrade. This website also uses AJAX. Which accounts need to be created to fix this problem? When I navigate to this URL, I get the message below:
The address is not valid.

I'm trying to create a page that displays a databound gridview to the user showing them the items being processed. Then the page should immediately begin processing. The problem is that the page never shows the gridview (or any other control) until the process is complete. The process is being sent to a WCF service. I've tried setting the page to async and running the wcf in async mode but the content still fails to display.
View 1 RepliesUsing C#, ASP.NET 3.5, VS 2008.
On a page with some user controls, I need to execute some lines of code only once (i.e. not on postback), however, the code must run after ALL page objects complete loading.
Example, Page1.aspx also contains uc1.ascx and uc2.ascx. If I imbed the code in a if (!PostBack) code block, it will end up running before the corresponding page load is completed for uc1 and uc2.
Is there a way to run the code on Page1.aspx once AFTER all the objects on the page have run thru their page load events?
I have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
Is it possible to inherit a page events to another page
like inherit page Init to another page...
I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?
I am experiencing an issue with the TreeView control when loading new pages. It is databound to web.sitemap, but when loading a new page, it does not select the node of the current page, just resets it to the root. THe new page loads fine, just not preserving the current navigation in the tree view.
