Web Forms :: Clearing A Form With Response.redirect?

Oct 12, 2010

I have the following default.aspx.vb


and I'm trying to clear the dropdown lists and the text box but also still give the thankyouLabel.Text message back to the user to give them some idea that their data has been submitted. I know that with a response.redirect that you're doing a postback but what I'm wondering is if there's a better way to clear a form so I can give users a clear form and also my thankyouLabel.Text message.

MVC :: Clearing ValidationSummary When Form Returns A Download Request?

Sep 20, 2010

Here's my setup:

Simple mvc page with a few controls that includes a validation summary area.

Once the fields are completed there's a download button.

If I enter something invalid, as expected, my controller code updates the UI with the appropriate error. However, if I then correct the error, and then click the download button a file is downloaded, but the UI never gets updated - presumeably since there's no update on the view.

MVC :: Clearing Output Cache?

Jun 26, 2010

I'm running an ASP.NET MVC website where several page controllers are decorated with an output cache attribute like:

[OutputCache(Duration = someduration..., VaryByParam = "*")]

These are typically forms where some lookup data are drawn from a database. These data change rarely, so the cache duration is typically set to 24 hours. Anyway, my question is: when the sql server is updated with new data in this area, is there a way of forcing such pages to "refresh" rather than keeping the cached output? Or if this cannot be done, is there at least a way of clearing the whole cache for the website?

ReturnURL Clearing Querystring?

Jan 26, 2011

Is it possible clear ReturnUrl from the server? I have a login page where the user logouts and I want to direct them to a specific page but when ReturnURL is set it overrides my redirect page.

Update:Ideally, I will only redirect a user who has just logged out versus someone who has bookmarked OR I will redirect regardless in special cases.So these are the cases:A link or bookmark -> should redirect to specified page in most case.A logout that has a returnurl -> should NOT redirect to the page,A special case -> should always redirect to my special case, i.e when a user needs to see something important

Is there a way to remove the returnurl from the logout/login status control?

Clearing Multiple Cookies?

Mar 23, 2011

The code below tries to clear the cookies for all domains once a user logs out of the system. For some reason, only the last domain in the array is cleared. Why does this happen? Am I doing something wrong?

For example, if I change the size of the array to 4 and then change the for loop to only go to 3, then it only logs me out of

As a sidenote, I have this loop working on a different server that uses a slightly different function to clear the cookies.

Edit: Code updated per suggestions below. Now it fails on the "as HttpCookie" line. Do I need to include some library?

Dim aDomain(12)
Dim ESidCookie, WIdCookie, EBidCookie, TSidAccessCookie, PSidAccessCookie, SSidCookie As HttpCookie

aDomain(0) = ""
aDomain(1) = ""
aDomain(2) = "" [code]....

Web Forms :: Clearing The Value Of A Text Box

Sep 23, 2010

I have a ddl that controls the visibility of a textbox (using panels). For example if i select 'Other' from the text box, a post back occurs and a text box appears beneath it for you to give further details. If any other value (for example 'dry') is selectedit's an accepted value and nothing else happens. Only problem is that if i select other, add details the text box and then go back and change the value to 'dry' (for example) the text box may dissapear but the value is still held within the box

Clearing Session In Global Application_Error?

May 10, 2010

Whenever an unhandled exception occurs on our site, I want to:

Send a notification email Clear the user's session Send the user to a error page ("Sorry, a problem occurred...")

The first and last I've had working for a long time but the second is causing me some issues. My Global.asax.vb includes:


When I run a debug, I can see the session being cleared, but then on the next page the session is back again!

I eventually found a reference that suggests that changes to session will not be saved unless Server.ClearError is called. Unfortunately, if I add this (just below the line that sets "ex") then the CustomErrors redirect doesn't seem to kick in and I'm left with a blank page?

C# - Catching An Exception And Clearing It Before ELMAH Gets It?

Feb 18, 2011

i have a problem where i have an exception being thrown that i am capturing in global asax. As part of this exception handling i redirect the user to a specific page because of this exception.

i also have ELMAH error handling with the email module plugged in. I do not want to receive emails for this exception. I also don't want to add this type of exception to ELMAHs ignore list, in case i want to do granular work around the exception (ie, only if it matches certain properties, happens on certain pages)

i want to:

write an Application_OnError that redirects a user to a page (i know how to do this part, more for procedure i've left it here) In the Application_OnError stop ELMAH fromrecieving this error after i've caught it

i am currently calling Server.ClearError() inside my App_OnError method, but am still receiving these emails....

Web Forms :: Clearing A RadioButtonList With Javascript?

Sep 24, 2010

I'm posting this here because my question isn't really about the javascript itself but about the workings of the RadioButtonList control. I have a webforms application where a several radiobuttonlist controls are rendered dynamically from server side code. I want to also render an undo button that will clear the associated radiobuttonlist. I can get it to work fine using an image button that does a postback. However, I'd like to do it without the postback, waiting until the entire form is filled out before posting back via a submit button. I've been able to get it to clear the radio buttons via javascript. However, when I click submit to post back to the server, the server thinks the radiobutton is still selected. Here's a condensed version of the code thatrenders the controls.


At run time, the radiobuttonlists and their associated undo buttons are rendered just fine. If the user selects an option from a radiobuttonlist and then decides they didn't want to answer that question, they can click the undo button and in the browser the correct radiobuttonlist is cleared. However, when they submit, it still saves whatever value they had clicked before to the database. It's as if there is something else on the page that is holding on to the selected value in the radiobuttonlist even after the javascript clears the control itself.
