I want to capture errors on a per-page level. I've added the following code to my code behind page:
public void Page_Error(object sender, EventArgs e)
{
Response.Write("Unhandled error on the page.");
}
I have also ensures that AutoEventWireup="true".
I have some gridviews on this webpage that use a SQLDataSource. I'm hoping to use this error message (which will be better when I get it working, response.write is mostly just to test) to cover up those errors with something more user friendly. Yet when I have an error ("Cannot open database" for instance), Page_Error never fires and I get the ugly yellow screen of death instead.
If I pass in true to the ValidationSummary() helper so that it only displays model-level errors, how can I get the summary to display custom errors I add to ModelState?For instance, here is what I am after. I want my data annotation errors to display next to the textbox's using the ValidationMessage helper, but in my business layer I may throw an exception that I want to display in the validation summary.
When setting up asp.net error handlers for things like 404 errors, it is more 'efficient' to do this in IIS, or handle it in the Global.asax Application_Error event? I know the latter will be called, and I want to log this information in a database, but should I then just return without any redirect and let IIS do the redirect, or would it be better to do a response.redirect inside application_error once we've logged it?
I wanted to use tracing to capture errors and programmatically send reports via email and text message...that if the ADMIN is eating out at a restaurant on a saturday nite he can see the text message/email to notify and capture..any way to do this??
I have to handle error related to web application. I am not sure how its works. I am thinking that I will add an error page (error.aspx) and in global.asax ,application_onError, I will redirecting the user to error page and that should be enough ! i mean it will handle error automatically.
how to implement page level and control level security in MVC applications. Also I would like to know the definition for Page Level and Control Level Security in MVC. Please refer me if any third party tools avilable to implement security in MVC.
I want to be able specify to do the following: Specify configuration settings such as appSettings and connectionStrings for multiple web apps in IIS7 No editing Machine.config or the machine-level web.config Web apps are distinct web sites in IIS (not subfolder apps) Is this possible without just duplicating the configs for each app?
I have the web page [URL] written in html. I have also created a form on this web page, but I do not have any idea how to create the aspx page to capture and email to me (via my mailserver), the data the user enters and submits through the form
I have a C# web forms ASP.NET 4.0 web application that uses Routing for URLs for some reason custom errors defined in the system.web section of my web.config is entirely ignored and it will fall back the IIS errors.
This gets entirely ignored
[code]....
This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.
During pageload i would like capture, which event is raised and its ID .e.g button click event , textbox value change event. I have tried by using the below code in page load but always iam getting only balnk value.
Dim lsTarget As String lsTarget = Request.Form("__EVENTTARGET").ToString lsTarget = Request.Form("__EVENTARGS")
I have a couple of pages with standard asp.net validation controls such as RequiredFieldValidator etc inside my RadAjaxPanel.As soon as I navigate to another tab in my RadTabStrip the page seems to force validation errors and pretty much "locks" the page even though non of the fields was selected to enter data.Only once all the required fields was entered the page seems to release the "lock" and only then am I able to navigate to another tab / page without even submitting the page.
what might be causing the "lock" and forced validation errors on the page?
Using jQuery I inject a partial .NET page with the AJAX load function:
function LoadNewsEditorNew() { try { $("#DivEditor").ckeditorGet().destroy();} catch (e) { }
[code]...
Now that I have my new form (with a submit button) injected into the page, I need to capture the button click so that I can do my insert.I know I can use a jQuery button click, but I really want make use of the button click event in .NET
I have a site that when a user logs in it sets their initials into a session variable and sets the timeout value like so:
[Code]....
I want the user to be logged in for 3 hours. This does not work, the session expires after a short period of time, maybe 20 minutes. What do I need to change to make this page level validation work?I have tried setting in web.config also, but this doesn't work either.
Basically, the reason I am disabling the cache is because I have DevExpress ASPxGridViews, which work great for filtering, sorting, etc. but the client is working with large amounts of data and has requested that we save the filter/sort between page navigations.
The way this is done is via an event that occurs, ClientLayout. The problem is, when the user navigates to a different page, and then clicks the browsers Back button, the events do not fire, and the unfiltered grid is displayed, presumably because this is what was cached. (However a link back to the grid's page causes the page to load properly, and the events to fire.)
The only way I have been able to solve the problem is to disable caching as pointed out in this link: http://forums.asp.net/p/1304752/2563283.aspx
Obviously, just because I CAN do it, doesn't mean its a good idea. I understand it might affect performance a bit, but can anyone tell me of any other problems that might occur? Maybe AJAX problems or controls giving out unexpected behaviour?
Last night i have ran my application which was workin 100%, but in the morning when i run it, it shows the error message in IE Status Bar Done but with some errors on Page due to this, my Menu and TreeView is not appearing well.
I have an error I haven't seen before. One minuter the debugging works fine, the next a App_Web_olwtcupi.4.cs opens in Visual Web Developer (2008) with the following code marked:
[Code]....
I don't know what I did, I've only written code in my aspx and aspx.cs files and I've never seen this before. This is not the first time I use Visual Web Developer, asp.net or c# and I'm truly puzzled..
On my aspx page I am trying to capture user input and then tried to save them in database and also trying to post them onto another page. Now I am using the following code on the button click event:ASPX CODE:
Now when I click save button then it the page waits and then I have to click again to close the page automaticallly and move to the next page. Can anyone tell me why I will have to click Save button twice to activate the button.
Now, on the pages that use that GlobalMaster page I have a button on each one which allows you to jump from one page to another,
basically I do a Response.Redirect.
What I am trying to do is to find a way to change the Title of the application according to the button that the user clicked. I was trying to get the current handler but that does not work well for me:
After working on a page for quite some time, the customer now decided that they wan't to be able to change a top level setting but still maintain the current page they're in.
Say for example:
User goes to default page, clicks on the UserSettings which is loading a partial view. In that partial there is multiple links like Address, Password, Other. Click Address (any of these) and it will load a partial within the partial. This will of course maintain the link "MyProject/User/1" in the URL bar.
When the User now change in the drop down in the top level, from User 1 to User 2 this will update the URL to be "MyProject/User/2" and will load the matching action with that. However, I wan't to be able maintain the user selection from before (MyProject/User/2, click UserSettings, click Address).
If I knew this from the beginning I would have done it completely different, but this now a request from the customer after the project is done so I'm look into if there is any "easy" way
[code]....
I can also add that I've tried to do something like this to figure out what exact page I'm on:
var foo = window.location.pathname;
but that only gives me what ever I already have in the URL bar, and not any information about what partial that potentially would be loaded. Is there any way to see what partials is dynamically loaded at the moment?
Basically loading View -> Partial View -> Partial View. Changing the setting for the View but still want to maintain View -> Partial View -> Partial View, but now for the new User
The Situation: When there multiple PageMethod calls in a single page, each of the method call holds a lock on the Session object thus blocking. The PageMethod calls can be made asynchronous only with @Page directive is turned to False|ReadOnly
Findings: When the Page directive is default (read/write) but the session is not used anywhere on the page, the calls are not blocked. Any read or write in to the session at the page level blocks the pagemethod calls.
The Problem: Making EnableSessionState=ReadOnly at the @Page directive is very restrictive and don't want to take that route. Can the pagemethod calls not block? and still access the session? (may be not write but just read)
