Does anyone know how to check in ASP.NET (C#) if Facebook is scraping a page? I'd like to be able to check on the server side if the "browser" hitting the page is actually Facebook (e.g. when it grabs details when a user is attempting to share a link).

I have a gridview control on my page that has two textboxes in its itemtemplate. When I type into one of the textboxes and hit the <enter> key, the browser returns to the page I was on previously. I have the textboxes set to not cause a postback and there is no ontextchanged event routine. Why would this be happening. What I want to happen when the enter key is hit is NOTHING or perhaps to sequence to the next tab stop.
I have two pages, step0 and step1.
Users get firsly to the step0 page, where they fill some info, the page updates, they fill some more, and then get redirected to step1 page.
Problem is that upon getting to the Step1 page, if the user clicks on the back button, then he gets to the last stage of the step0 page, which uses sessions and variables that are no longer existing, what causes a crash.
I'm looking for an elegant way to make sure that with each page visit, the page will restart itself to start phase.
I have this idea maybe twitching the Page_Load function, something about the is_post method, but since each page's post back hits this function,
I am having an odd issue where when I hit the 'enter' key, a button on my page (not on the Popup) is being activated. Consequently, it is firing a command that I do not want fired.Put another way, I have a ModalPopup with a 'TextBox', 'Image', and three buttons. I can click inside of the TextBox, begin typing, then hit 'enter', and for some reason it acts as though I am clicking on a button that is on my page, not on the Popup.
View 1 RepliesI was just typing on an old site of mine that requires the constant contact method that uses threading and an update panel to prevent users from being logged out since despite setting the timeout period in web.config to what mathematically should be millions of minutes people still seem to get logged out after like 5 minutes. I tried the web service method, but it was ineffective.
The constant contact with an update panel accomplishes its primary objective well, however when a user clicks on their keyboards back button at the wrong time they get redirected to the previous page and if they click the forward button in their browser the page contains none of their typed data.
Is there a way to override whatever causes the backspace button to do this?
I have a modal popup and the CSS prevents anything from being entered on the main page.
However, when I hit enter while the modal popup is displayed, a button on the main page is fired.
It seems to only happen if the button on the main part of the page is pushed down out of view so it is not currently on the screen.
How can I prevent a button on the main page from firing when the user hits enter?
I have a master page which includes a search textbox and a button which posts back to another page. The controls are defined as follows:
<asp:TextBox
ID="SearchTextBox"
runat="server"
style="margin-left:
0px"
Width="170px" />
<cc1:TextBoxWatermarkExtender
ID="SearchTextBox_TextBoxWatermarkExtender"
runat="server"
Enabled="True"
TargetControlID="SearchTextBox"
WatermarkCssClass="watermark"
WatermarkText="Search Name" />
<asp:Button
ID="SearchButton"
runat="server"
Text="Search"
PostBackUrl="~/SearchPage.aspx"/>
The problem is that for any other TextBox on the page which is using this MasterPage, for example the login page, if you type your user name and password and hit Enter, The page is redirected to the SearchPage. If you click on login buttton everything works fine. How do I make sure hitting enter on the page in any other text box does not post back to SearchPage.aspx?
What ASP.NET page lifecycle event can I write code in to determine the size of the viewstate that being sent out? Also, is it possible to determine the size without parsing through the rendered HTML (like a property on the page object) or is parsing the only way?
What I'd like to do is log the sizes, specifically if they cross a certain threshold.
I want to know how can I determine what was the back page using C#?

View 6 RepliesI'm using Forms Authentication. Is there a way to determine whether a page (or request) required authentication or not? My site has logged-in areas, and logged-out areas (all set in web.config under authorization sections), and I'd like a good way to know if asp.net required authentication to be set or not.

I use a separate project for my data layer and call one class within it clsData.cs. I'd like to know which page from the Presentation Layer (in another project within the solution) has referenced it from the clsData side, if that's possible.

ID="hyper1"
runat="server"
NavigateUrl='<%#string.Format("~/PLayer.aspx?ID={0}&Type={1}",Eval("arrange_by_id"),Eval("value"))%>'><%# Eval("value")%></asp:HyperLink>
I've implemented this string format in my NavigateUrl to pass a dynamic querystring depending on the clicked item!
but you see the first part in the string format where it says "~/PLayer.aspx" i want the user control to automatically change this part according to where it's placed!
I have a MasterPage, several content pages - each of the content pages have a UserControl.
In the MasterPage, I'm setting the Page.Title programmatically based on Page_Init "Request.UserAgent.Contains....", so that the content pages end up with different page titles based on this.
Each content page has its Title set to blank (Title=" "), but when the page renders, the pragmatically generated page title shows up in the browser tab.
In the UserControl code behind, I need to access the content page's (parent page) Page.Title value, and base on this, display some text:
If(Page.Title == "something")
{
Lable.Text = "something";
}
else if (Page.Title == "somethingElse")
{
lable.Text = "somethingElse";
}
However, my label remains blank when using this code. What is the way I need to determine the current Page.Title to what the MasterPage has set it as?
I'm looking to alter the way my asp .net webpage is output to the browser depending on the css media type being used. Although the css is generally taking care of the differences in appearance between screen and print mode I would also like to make some minor adjustments to the markup when print mode is required. I would simply be dropping a floated section down below its sibling rather than as a 2 col approach which is to used during screen layout in the browser.
View 3 RepliesSo, I have web apps with web.configs like so:
<authorization>
<deny users="?"/>
</authorization>
<location path="SomeUnsecuredPage.aspx">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
In other words, most pages require authentication and authorization, but some don't.
Then I have an IHttpModule that will be used by all the different applications. All I want to do is check if the current request is "secured" at all. If the page doesn't require authorization I don't want my IHttpModule to do anything at all. I am using FormsAuthentication and I assume that FormsAuthentication already has all of this information cached somewhere, doesn't it? Also, since this check will be running constantly so it has to be very quick.
I am currently subscribing to the HttpApplication.AuthorizeRequest, but surprisingly this event fires even for resources that allow anonymous access.
I have an application which use some javascript functions,As all javascripts include in Masterpage, most of them which comes withpage are not necessary, and some of those are repeated ( cause used in some different JS file. )So I want to check if there is a way to determine duplicate functions and remove them ?

View 2 RepliesI need to check if an authenticated user is authorized to access a directory. I have done this before with a base class library method, I just cannot remember what class it's part of or what it's name was. I think the method was a static method and the class may have had the word Utility in it's name, but I just can't remember or find it on the net. BUT I KNOW I HAVE USED IT! The method definition was something like:
bool SomeTypeWithTheWordUtilityInTheNamePossibly.VerifyUserIsAuthorized(Principal user, string virtualPath)
I'm not using a roles provider in this application and I'm not planning to.
Im working on a website where users can log into a members area, inside this area they will be able to communicate with other members.
In order to keep an accurate list of who is online and who is not, I would need to update a IsOnline field in my database when they log on and when they exit my website..
The login part is easy, but how can I determine if someone is leaving my website to go to another, or closing the browser.
