Web Forms :: How To Detect And Prevent New Browser Instance

Aug 25, 2010

The web app in question provides a UI for editing a client (in the business sense, not the browser sense), identified by a ClientID. I store the ClientID in Session, which gets passed from page to page, along with a number of other pieces of data in Session. Works great.

The problem is that if the user opens a new browser window using Ctrl N or File->New Window (in IE), the new window comes up with the same page as the current page, with the same session info. Then if the user navigates to a different client in the 2nd window, the ClientID in session refers to the new client. If they go back to the original browser window and save, the original client gets saved using the 2nd ClientID, and all hell breaks loose, because now the data from the two jobs are intertwined.

I have enabled trace and verified that the new browser window uses the same SessionID as the original. If an entirely new instance of IE is opened, it has a different SessionID, so is not a problem. I have not yet investigated other browsers, such as Chrome or Firefox.

Is there any way to determine if a browser instance is opened for a web app which is already open in another window or tab? Or to prevent that from happening?

VS 2010 - Prompt User Before Navigating Away From A Page And Perhaps Stay On Page

May 15, 2012

I need to check information the user has entered on a page against what I have in my database to see if he is entering duplicate data. It is up to him if he wants to proceed or not. I just need to alert him.

The problem is I don't own the button that he clicks so I can't hook up a javascript confirm to the button click. I am running within vendor code. I have an "override PageLoad()" procedure where I can test what page they're currently on. If they are on page "EditForm.aspx" and would normally navigate to "UserFinish.aspx" without any custom code of mine "interfering", I want to test what they've entered on EditForm.aspx and present them with a popup if they've entered duplicate info, and if they click OK button then proceed to UserFinish but if they click Cancel then stay on EditForm.

Page Causes Validation Errors When Navigating To Another Page - Tab?

Mar 31, 2011

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?

C# - Prevent Opening Of Application On Browser Refresh?

Dec 19, 2010

I have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:

<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />

This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.

I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.

Edit

I've accomplished this by doing the following:

protected void Export_Workbook(object sender, EventArgs e)
{
Response.Redirect(Request.Url.AbsolutePath, false);
ItemList.Prepare_Workbook();
}
