I think what you want to do is send in your email something like this:
http://myserver/myapp/MyPage.aspx?ID=68
Then in your page_load event, you could use the following to get the ID.
myParam = Request.QueryString("ID")
In the above example, it would return 68, which you could then use to perform a database lookup.

Hello Friends,
I want to have radiobutton in GridView. But only one RadioButton must be selected and also as i select a radiobutton then that row's id should be displayed
|
|
|
|
|
Use Gridview Template Field.

HI,
Use Templatecolumns for placing radio buttons in gridview and after that by using javascript or server side code you can hide/visble the rows ...
|
|
|
|
|
use the following code into <column> </column> tag of your gridview
<asp:TemplateField HeaderText = "Check">
<ItemTemplate>
<input id="Radio1" type="radio" name="ss" onclick="sel(this)" />
</ItemTemplate>
</asp:TemplateField>
sel() is a js function you can use code of selecting current row
<script language="javascript" type="text/javascript">
function sel(srcElement)
{
alert('Ok');
var cb = event.srcElement;
var curElement = cb;
while (curElement && !(curElement.tagName == "TR")) {
curElement = curElement.parentElement;
}
if (!(curElement == cb) && (cb.name != "cbxSelectAll")) {
if (cb.checked) {
curElement.style.backgroundColor = "gold";
rowsSelected = rowsSelected + 1;
}
else {
curElement.style.backgroundColor = "white";
rowsSelected = rowsSelected - 1;
}
}
}
</script>

How can I send as a response a redirection to an external link?
With asp.net I was using Response.Redirect("externalLink")

That should work. What is the problem you are facing?

Hi,
i want fullpath when i select a file it works in IE but not in safari..firefox...etc..
FileUpload1.Postedfile.FileName returns the filename along with its full path which have to be uploaded in IE, but it returns only filename when we run application in Firefox.
if any body knows any replacement function then plz let me know.
Thank you

You've been asking this for days. I still don't see how knowing what path a file came from on the clients computer, is of use to you. If it is, write an activeX that will help you get to that info.
If you knew anything about ASP.NET, you'd know that it generates HTML, and no matter what the platform, you've obviously hit a limitation of the control in FIrefox ( some would say, a security feature ). I'd be amazed if there's a way around it without using a java applet ( ActiveX won't run in FF, of course )

In other browser...when load the file from specific path...that full path is not coming..
----------------------------------
string filePath = FileUpload1.PostedFile.FileName; -->comes full path in IE not in other browsers...
//Load the file
FileStream stream = File.OpenRead(filePath);-->bug is coming here
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
stream.Close();

Well that's just plainly not going to work. The server part at the start should be a bit of a giveaway...

Well, there's a surprise. If you're new to ASP.NET, why are you working so hard on this issue ? Surely you're not writing code that you're paid for ? You're new, so you'd be learning, in a class, or by yourself, right ? So drop the firefox thing, it plainly won't work, and you'd have to be very dishonest to be doing paid work when you're new, so whatever project you're doing for fun, just accept that Firefox doesn't do what you want it to, and move on.

Try this!
string strfile=Path.GetFileName(txtUpload.PostedFile.FileName);
string strdr=Request.PhysicalApplicationPath+"<name of="" the="" folder="">\\";
