I have something like this:
bool preventEvents;
protected void Page_Load(object sender, eventargs e)
{
preventEvents = doSomeValidation();[code]....
EDIT:
got some interesting answers (thanks to everyone) but not what i was looking for, maybe i should be more specific:
given some condition, is it possible to skip all events after Page_Load and just jump to the rendering, without manually removing/mapping each event?
Im using intelligencia urlrewriter as my url rewrite module. I have one very strange problem which only occurs when an url is rewritten but to make it more fun, not on all rewritten pages. Edit: Forgot to tell you what's the problem boing boing. the problem is that my Page_Load event gets fired 2 times.his is how my form rewrite adapter looks like:using System;
using System.Web.UI;
using System.Web;
using System.Web.UI.WebControls;

've recently set up an ASP.net site (not using MVC.net) to use URL Routing (more on the code below) - when using user controls on the site (i.e I've created a "menu" user control to hold menu information) the page_load event for that control will fire twice when URLs have more than one variable passed over.
i.e.
pageName/VAR1 : will only fire the page_load event once.
while
pageName/VAR1/VAR2 : will fire the page_load event twice.
*Multiple extra VARs added on the end will still only fire the page_load event twice*.
Below are the code snippits from the files, the first is the MapPageRoute, located in the Global.asax :

Note, that when I'm just hitting the page and it uses the default values for items, the reloads do not happen.
I'm using a .js file to bind events to controls. I'm also using UpdatePanel to do async postbacks; however, when they postback,the controls lose the events that were initially bound to them. Is it possible to rebind the events in the Page_Load function by using the .js file?

View 1 RepliesI thought that Page_Load events executed every time a page was loaded not just the first time. Am I wrong on this?
I have a Page_Load event that writes text to a label to display on the screen: Output.Text &= "Welcome to my Website <br />" (Output being the ID of a Label control)
I also have an On_Click event for a button to display the same information: Output.Text &= "Welcome to my Website <br />"
After clicking the button, I expected to see the output twice. Once for the page being reloaded and once for the click event. I thought that Page_Load events executed every time a page was loaded not just the first time.
I am using a LINQ to SQL data source for a ListView and perform a validation check in the Listview ItemUpdating event:
[Code]....
This works great and keeps the user from updating the record with invalid data.However, when I hit cancel after this operation, it saves the text in the box rather than cancelling the operation. Here's my code for the update button:
[Code]....
Update Function:
[Code]....
I do not handle the cancel button event, as the cancel operation has worked fine... unless someone enters incorrect information and e.Cancel is set to true.What am I doing wrong? Is it the mixture of using the LINQ Datasource and doing my own updating?
I have a text box that I am reading mulitple employee names into. If the user enters a name that does not belong to an employee I want to cancel the item_updating function. Here is my code:

I'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 RepliesSo I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.

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.
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?
Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.
How to wire up HTML server controls events?
I added a Input (Text) control in my web form and turned it into an HTML server control so its an instance of HtmlInputText class.
If I double click on the control It only adds a OnClick event handler method inside the script tags in the HTML doc of the web form but how to I get to handle its Serverchange event exactly? does VS.net 2008 has no ability to auto wire up the event to the control, do I have to manually wire up the event handler?
Is this true? it is not possible to change the content of the buttons in the dialog displayed by the confirm function
This is my code to display a pop-up the our user to confirm his data:
Code:
Queue queue = (Queue)(handlerPages[HttpContext.Current.Handler]);
if ((queue != null))
{
StringBuilder builder = new StringBuilder();
int iMsgCount = queue.Count;
builder.Append("<script language='javascript'>");
string sMsg = string.Empty;
[Code] ....
The user wants to see Yes/No instead of OK/Cancel. It's true I can't use confirm?
I did not write this code and I'll admit I don't understand it, so the first thing I will do is dissect it. But do I also have to rewrite it?
CheckPara is my OnDataBinding procedure SqlDataSource1 is ObjectDataSource (it's only confusing name)
Language is Nemerle, but if you know C# you can read it easy
protected virtual CheckPara(_ : object, _ : System.EventArgs) : void
{
foreach(x is Parameter in SqlDataSource1.SelectParameters)
when(x.DefaultValue=="") //Cancel binding
}
so how can I cancel binding when there is not fully configurated ObjectDataSource ? Or... how can I run binding only when I done with all parameters ?

View 1 RepliesI have a web page (.aspx) that calls a third party web service to get some data. It usually takes couple of seconds to get the response back, and then the rest of the page will load. Occasionally the call gets stuck either due to the web service is down, or internet connection, etc., the page just hang there and will not load.
My questions is:
1) Is there a way to abort/cancel the web service call after a set amount of time?
2) Is it even possible to verify the status of the web service before calling it?

View 2 RepliesI have a page on which I have two forms, which really act as a main form and a subform. I can put a Cancel button (which removes any inputs I have made in the form) on each form. But I want to put just one Cancel button that Cancels the input for both forms. I know that there is a Form.UpdateItem, Form.InputItem, and Form.DeleteItem, but I can find no Form.CancelItem. Is there a way to emulate the Form.CancelItem programmatically?

I have two buttons: Save and Cancel. I have set CauseValidation = "False" for this cancel button. But when I click the button for the first time, it still causes validation while it does not cause validation if I click it again.
I tried to fix it by defining validation group for all validation controls, controls that are validated, and save button. But still the cancel button would validate when first time it is clicked.
how to fix it?
