Have you thought of changing your workflow?
Upload the file to a temporary area. Then makes the check for overwrite and inform the user if that is the case.
If there is no overwrite needed or the user permits the overwrite then move the data from the temporary area to the permanent area. If the user declines the overwrite then delete the data in the temporary area.
NOTE: By Temporary area I do NOT mean TempDB

Can't you keep buttons and gridview on same form??
If not then do something like
Session["click"]="button1" // on the click on Button1
Session["click"]="button2" //on the click on Button2
In the page where you have gridview check..
If(Session["click"].Tostring()=="button1")
//Disable your gridview link buttons
else
//Enable your gridview link buttons

You're not likely to 'find' them, you're better off parsing them on the way in, during data binding.

You should never use the design view anyhow, it has always been rubbish.
Having said that, you should be able to see your pages in the design view, there's no reason why you would not.

I agree.
Designing through design view means lots of unnecessary html styles which is just increases your page size.

hi...
In my application i created a generic handler an i called the generic handler in my page.. the code is given bellow
<asp:gridview id="GridView1" runat="server"
="" gridlines="Vertical" autogeneratecolumns="false">
<columns>
<asp:boundfield datafield="Video_Name" headertext="Name">
<asp:templatefield headertext="Video">
<itemtemplate>
<object id="player" classid="clsid:6BF52A52-394A11DB153-00C04F79FAA6" height="170" width="300">
<param name="url" value="<%# "HandlerAudioVideo.ashx?id=" + Eval("id")%>" />
<param name="showcontrols" value="true" />
<param name="autostart" value="true" />
but when i use this codes in mozilla and safari it does nt call the handler but when i use IE as my browser it gets called and the page is function as well...
Oopppzz!!!!!!!

clsid can be accessed only through IE.
Use object tag for IE only...
For Mozilla or Safari use Embed Tags.

If the PDF is in your Website and on a aspx page, then its simple , because you have to check if the user has logged in first before a user can access the secure page. If you are not doing that, then you have to start doing it

Also if you dont want to create asp.net pages to check authentication, you can also use custom HTTPHandler for .pdf files.

That is Correct

On the contrary, Vuyiswa, it is not as simple as you explain.
I have encountered a similar problem before.
I think the original question was: "If a user knows the absolute url to a pdf, how can we prevent them from seeing it?"
Obviously, since the pdf files are most likely kept in a virtual directory of a website, opening them should not be a problem at all (if one knows the virtual directory and the filename).
The way I did it was, I kept the pdf files in a private folder and read them using System.IO, then through the application streamed them and eventually displayed them.
I have tried various things, but the way I did it seemed like the most reasonable thing to do, and, well, secure (hopefully).
var question = (_2b || !(_2b));

The way I do this stuff, and the best way, is to have a http handler, which will not return the file ( whose actual path is hidden ), unless the link came from my site also.
