I'm going to check the database schema at Application_Start event handle in the Global.asax file. If something wrong, I hope to stop the application instead of just catch an exception.
View 2 RepliesI have a repeater and a user control on my page, when any of the items in the repeater are selected this refreshes the user control accordingly. However I found that if I selected another item before the page/user control had finished to load it produced an error, when left to let the page/control fully load and reselect no error.Clearly this is interrupting the code before its finished, can I stop this from happening by doing some sort of check to see if the user control has finished loading?

When i stop the stop watch i want to display the stopped time in msg box how i get it?????
I use a validation control to check if value entered is numeric. When I type letter in the textbox, the error messages shows for a second, then the application continues, and eventually throw exception.
I'm going to add server side validation in code behind. But I wonder why the validation control doesn't stop the application. I don't see any difference between this web form and other web forms where validation controls work fine.
I'm executing one stored procedure from the '.net' code. Since there is a lot of data, it is taking too much time to execute. Is there any way to stop this execution from the c# code?
In other words, if we execute the query from database itself, there is a option to stop its execution but in the code is it possible?
I am launching a click once application on button click. I am using Response.Redirect(http://domain.com/application.application) to open my click once application. If I click on that button again then I am able to open one more instance of that application again. I want to put a restriction so user can open only one application.

Currently users select a record in a gridview and click on the delete button. Delete button passes certain variables to identify the record, makes a SQL connection and then deletes the record by executing a stored procedure. This is way the delete button's code behind works. Now we need a confirmation box if a certain flag is False. If the users select YES then they should be able to delete any way otherwise clicking on Cancel should stop the operation. I don't want to use the onClientClick event of the button like many examples on Web show, instead I am using the jQuery, that uses the button ID and pops up a confirmation dialog. The issue I am having is even if the Cancel button on the confirmation dialog is clicked it still goes on to run the code behind, executes the stored procedure and deletes the record. The browser being used is IE 7.0, how do I stop the button from running the code behind in the button_click event if they select cancel?
I have tried return false, e.preventDefault();event.propagation, event.returnValue = false etc but can't stop it. Here is the jQuery, that goes to the webservice when clicked and determines whether to display the confirmation or not when another stored procedure returns the record count of 0 or more. Like I said it works fine in getting the flag value from the SQL but does not stop at the client level and continues on to the code behind of btnDelete.
$(function() {
$("#btnDelete]").click(function(e) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "WebServices/myServices.asmx/ConfirmDelete",
data: "{}",
dataType: "json",
error: function(req, msg, err) { alert(req, msg, err); },
success: function(msg) {
if (msg.d == 0 && !confirm("Do you wish to delete this record?")) {
event.preventDefault();
return false;
event.returnValue = false;
}
}
});
});
});
I have an ASP.NET page and have a couple of linkbuttons and Iframes. The pages in side of these IFrame take long time to load, I want the user to navigate to another page by clicking one of the linkbuttons. Now, it looks like it is waiting for the the iframes to finish loading when i click on a link button, the page is still trying to load (instead of navigating to different page).
Is there any way I can stop the iframes to load and go to another page?

View 4 RepliesI am working on an ASP.NET project. When I am debugging, I often want to switch back from my browser to Visual Studio (2008) and edit some code. Visual Studio then won't let me edit the code, unless I explicitly quit debugging first.
Is there any way to configure Visual Studio such that is automatically stops debugging and allow me to edit the code, or do I have to stop it manually each and every time?
Disabling Edit and Continue does allow me to edit the code, but this does not force VS to stop debugging...

I am using asp.net 3.5 and have validateRequest="true" in the machine.config.
Do I need to do something special to stop CSRF and Cross Site scripting or asp.net will handle all these?
Whenever I stop debugging an ASP.NET IIS web application it seems to take very long before VS2010 becomes responsive again (2 or 3 minutes). This happens when I close Internet Explorer 9 (which stops the debugging session), stop debugging in VS (which closes the browser) or when I detach the debugger from the debugging menu (which leaves the browser open).
My CPU time for devenv.exe goes up to 25% during this period of time. I use the professional edition (no intellitrace). Starting without debugging performs ok when I close the browser. I have some add-ins and extensions installed like TestDriven.NET, Resharper, PowerCommands, Productivity Power Tools, VisualSVN,...
Imagine a Web Forms application with routing.
A clean page name like:
[URL]
Might have an underlying of URL of:
[URL]
If a user enters [URL] into a browser, I need to redirect to [URL]
Is this possible to do?
I can't work out a way to do this as the routing engine is not executed for a physical page and in the page.aspx Page_Load method I have no way of knowing whether the URL was entered directly or was the result of a route.
I have an annoying problem with Visual Studio 2008.
When I run the "format code" command ("control+k, control+d") -- it will insert a carriage return. How do I get it to stop doing this?
For example:
<label for="shipCompanyName">Company Name:</label>
undesirably becomes
<label for="shipCompanyName">
Company Name:<label />
This is a really odd situation, so hopefully I can explain it well enough.
I am deploying an ASP.NET 4 webforms application to a Windows Server 2003 SP2 server running IIS6.
Here's the problem -- when the application pool recycles its worker process (w3wp.exe), about 80% of the time, I will get an ReflectionTypeLoadException error trying to access any page in the app that contains an EntityDataSoure every time I try to view it.
However (this is the interesting part) -- the other 20%, it works just fine. I've actually resorted to turning off recycling the worker process entirely for this application pool and just add/remove whitespace from web.config forcing the site to recompile until I get a "good" w3wp.exe.
If this isn't clear, what I'm saying is: the actual worker process doesn't work at all for pages containing an EntityDataSource for about 4/5 times it starts, but still manages to serve all other pages just fine. Once you get a worker process that manages to serve a page with an EntityDataSource, it works every time until that process gets recycled.
My question is, how can I debug this? It works fine on my dev machine, it works fine on the server as long as you get a good process running, but iisreset or a server restart or anything that kills the worker process is almost guaranteed to cause the site to not come back up and throw this ReflectionTypeLoadException.
