You say the files is within the reports folder, so I assume ASPxDropDownEdit1.SelectedItem.Text is the file name. Could it be the '*' that is the illegal character?

Yes I am suspicious about the value there as well. The OP should debug it and if the value has a illegal character or not.

Try the following and let me know your feedback.

C#

string FileToDelete;
FileToDelete=ASPxDropDownEdit1.SelectedItem.Text.Trim().ToString() + ".pdf";
// Set full path to file
FileToDelete = Server.MapPath("~/reports/"+FileToDelete+");
// Delete a file
File.Delete(FileToDelete);

Solution 1

File.Delete does not accept wild cards, so the * is an invalid character.

You could try iterating over all the files that match the search pattern like this:

C#

DirectoryInfo directory = new DirectoryInfo(Server.MapPath("~reports"));

foreach (FileInfo file in 
         directory.GetFiles(String.Format("{0}*.pdf", 
         ASPxDropDownEdit1.SelectedItem.Text)))
{
    file.Delete();
}

Hope this helps,
Fredrik
