hi, i have set a condition on the upload function

ASP.NET Syntax (Toggle Plain Text) 
  1. if (FileUploadControl1.PostedFile == null) {
  2.  
  3. lblResult.Text = "Please select a file first";
  4.  
  5. }
  6.  
  7. else
  8.  
  9. {
  10. //upload a file
  11. }

but if i press upload button when no file is selected it still uploads a blank file regardless of the "if' condition i set, does any1 know why this might be?

cheers

Try this:
if (FileUploadControl1.HasFile)
{
    //upload a file   
}
else
{
    lblResult.Text = "Please select a file first";   
}
