Why? That path only makes sense on the client computer, the server can't use it for anything.
Some browsers doesn't return the comple path, and some antivirus/firewall software removes the complete path, so there is no guarantee that you will even get the complete path to the server.

Hello,
i want to allow users to copy an entire row from excel, and then with one "ctrl+v", this row will be pasted to a gridview in my web app. is this possible?
Thanks in Advance.

You could provide a textbox which you can paste the row into which can then be processed and added to the gridview, the input of the textbox could easily be split at vbTab.

before doing DataBind set the DataValueField of the DropDownList.
ddlCategory.DataValueField = "CategoryID".
Get the value of Selected Item Using
ddlCategory.SelectedValue

The problem is not with the DropDownList. You better find a Good ASP.NET book to quickly learn the basics.

What a disaster.
Why are you using ToString ? Why are you passing an object ?
If number == null, this code will give that error. If you're using .NET 2.0, I'd suggest passng an int?, checking for null, then using if number < 0 instead of a tostring call that may not work for all locales and is needlessly expensive.

Hy
I have a site on a host for ASP.NET.
I have a file with 30000 records.
I have a .mdf file with a table with 30000 records.
Method 1
I read from file a record and diplay in a label.
Label1.Text = File.ReadAllLines(Server.MapPath("~/fisier.txt"),Encoding.UTF8)[index];
Method 2
I read from .mdf file from my table the same record.
Can tell me witch of the 2 method is faster?
thx

Probably the second, but both are a disaster, obviously.
Well, readalllines returns a string[] as I recall, so it won't compile. ReadAllText is probably faster than the database solution, as it mindlessly reads and passes a single string.
This does NOT mean that flat files are faster than databases.

Method 2 is by far the most efficient. A specific record in the table can be accessed directly without having to read all of them.
The ReadAllLines method will read the entire file and create an array that contains 30000 string objects. The memory used for this will be approximately double the file size, plus 120 kB for the array object itself.
A less wasteful method to read the file would be to use a StreamReader to read line by line until you reach the line you want. That will not create a huge array in memory, and you don't have to read the entire file.

hi
i want to save a file to server. this is the code i'm using in my project.
if ((FileUpload1.PostedFile != null) && (FileUpload1.PostedFile.ContentLength > 0))
{
string fn = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
string SaveLocation = Server.MapPath("Data") + "\\" + fn;
try
{
FileUpload1.PostedFile.SaveAs(SaveLocation);
Response.Write("The file has been uploaded.");
}
catch (Exception ex)
{
Response.Write("Error: " + ex.Message);
//Note: Exception.Message returns detailed message that describes the current exception.
//For security reasons, we do not recommend you return Exception.Message to end users in
//production environments. It would be better just to put a generic error message.
}
}
else
{
Response.Write("Please select a file to upload.");
}
'Data' is afolder in the server. iwant to store the file in that folder. but its not working properly. its showing a config error while running. is there any additional settings needed?

Why not use Path.Combine ?
