The page you describe above is a Java Server Page (JSP)
The refresh is because the code is ran at server side and then posts back
AJAX does not refresh so maybe try that, the cascading drop down you want to look at

Well you need to install ajax
Create two dropdown lists
set cascading properties as so:
CascadingDropDownProperties cProps1 = CascadingDropDown1.GetTargetProperties(ddl);
then post once you have done that

OK, so all I want to do, is to store the URLs I use for links, in a resource file. Is this possible ? Apparently not.
I need to have a hyperlink column in a datagrid, which uses a URL from the resource file. The trouble is, when I get it into a form that compiles, it won't run, because a resource file is internal, and resets to internal whenever you change it. But, despite the file being in the same project as my page, internal means the page cannot access it.
Is there any way around this ?
Oh, and the DataNavigateUrlFormatString cannot be build from a code behind method at all. The <%= syntax is plain ignored by so many controls, it's hard to work out where it will work and where not.
<asp:HyperLinkField DataNavigateUrlFormatString='<%=VMSURL.ViewURL%>' DataNavigateUrlFields='IDRequest, CaseNumber' DataTextField="CaseNumber" HeaderText="Case #" Target="_blank" />
Renders the <%= syntax verbatim
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink runat="server" Text='<%# Eval("CaseNumber") %>' NavigateUrl='<%# string.Format(VMSURL.ViewURL, Eval("IDRequest"), Eval("CaseNumber" ) ) %>' />
</ItemTemplate>
</asp:TemplateField>
Throws an error because VMSURL does not exist. Changing the resource class to public fixes it, until I edit the resource file and it goes internal again.

I got this sorted, I just added a property to the code behind that returns my string from the properties. Still stupid tho.

I am using server variables in the code like:
Response.Write("Some text" & Request.ServerVariables("Somevariable"))
During code review, it was put under vulnerability(Cross site scripting).
I have thought of two solutions for this
1. Create a list of valid URLs and put a check to verify noone has manipulated it.
2. Create a funtion to strip out potential CSS hacks. It will remove characters like '<','>','\r','\n' etc.
Which solution should I stick to? Or is there any other better solution to this?
Will the solution be able to remove response splitting vulnerability as well?

This should work. Along with that QueryStrings should be encoded (escaped in JavaScript) suitably.

Could you elaborate on that? When i use standard authentication everything work fine but when i use custom authentication and authorization i can not work with WCF service. I get error from title. Is there a difference between custom authentication and authorization in .net 2.0 and net 3.5?

Step through the code that should set the value. I prefer to use null as logged out, because it always starts as null, right ?
I have to assume it's not being set, but you need to set breakpoints and examine the session to work that out.

I think your design is not good. If you do so, each user visiting your site will have a session variable even though they are not willing to log in. I suggest you to create session when user logs in and clear it when user logs out. Don't depend on the global.asax.
When user logs in, create session["status"] and keep true value there. When user logs out, remove this session entry. You can check the user logged status by checking this session existence. If session["status"] is returning null, your user has not logged in.

Hi, Are there any downloadable forums written in ASP.Net. Preferably, open source. Like www.phpbb.com
Thanks

Did you look at the starter kits from www.asp.net[^]?

Thanks. I checked that but I couldn't see any stand alone forum package. There is some plug-in for DotNetNuke project which is not I am looking for.

When a user clicks on a link to download a file, does anyone know a way to force a user to save a file to their machine instead of opening it directly? Or a way to at least prevent them from opening it directly?
We have a csv file that we are providing a link to, but in the File Download prompt that appears there are open, save, and cancel buttons. We only want the user to be able to select Save or Cancel. Is there a way to do this even if it is in server settings or IIS?

We do something similar with a few Response.Writes (prolly not the best way) to allow them to download a dynamically generated file, we've tried changed the MIME-type, but most browsers seem to ignore it and base those options on what the file extension is. i've tried setting it to a video mime type, but the browser (IE7) still wants to open the .csv file in notepad(normal default is excel, i changed mine to notepad). I'm fairly sure that links function in a similar fashion, and that the options presented are solely dependant on the clients browser settings. Although i could be completly wrong, and i'd like to know if i am, i dotn think there is a way or at least a way that the client wouldnt be able to turn off, to do what you want. If you find a solution i'd love to hear it, it would be nice to have that functionality on my downloads site. Sorry i couldnt be more helpful.

The File Open/Save dialog is upto the web browser. I don't think you can have granular control over, for security reasons.

problem regarding thumbnail generation.
I am beginner in Asp.net(Asp.net with C#) and facing a problem please help me. 
Problem:-
My problem consists of three parts:-
1]
my application displays images on a web page i want to show images in the form of thumbnails.Now i want to arrange these thumbnails in alphabetical order, there will be 26 thumbnails on my web page each thumbnail represents images belongs to that particular alphabet.
for example my first thumbnail is for images whose name starts from letter 'A'.
2nd thumbnail is for images whose name starts from letter 'B' and so on up to letter 'Z'.
2]
second requirements that images should be sorted out according to their names in ascending order for that particular alphabet and first image should be displayed in that thumbnail.
for example:
there are 4 images whose name starts from 'A'
Adriana,Angelina,Aaliyah,Alice. so it should sort images in the following order
Aaliyah,Adriana,Alice,Angelina.
and the thumbnail which is displaying images for alphabet 'A' should display image of Aaliyah.
same is for images staring from alphabets 'B','C' and so on up to 'Z'.
3]
Third requirement is that when i click on that particular thumbnail it should take me on another page which contains all images in the form of thumbnails starting from that letter.
for example i click on Aaliyah then it should take me to the next page where it will show
thumbnails of Aaliyah, Adriana, Alice and Angelina.
Also tell me about the design view(.aspx file) whether i should use html table to display images or datalist?? i am a beginner so pls help me.

Assuming you're getting the information from a database, it would be easiest to make the DB do the sorting for names and whatnot. A repeater control (if it hasnt been depricated or removed, i've been living in .NET 1.1 for a while and have only recently upgraded) would do what you'd like, it simply repeats the defined HTML for as many records(rows) as in the dataset it's bound with. I like them a lot for data that needs to be formatted the same way. The Navigation could be handeled with a ItemCommand event, that does a Response.Redirect to whatever page you want. This would also let your page display images based on the data in the database and not a static data structure or HTML, letting you add or change images easily. Hope i helped or at least pointed you in the right direction.
