I have a  simple asp.net form that is uploading an image.
Even though I put the max-file-size in my form, it's not stopping the page from working and the user just gets an error.
how can I stop the script from erroring and ask the user to retry their.
I am using asp.net 2.0
Thank you

  <form id="form1" runat="server">
            <div>
              <asp:FileUpload ID="FileUpload1" name="FileUPload1" runat="server" />
                <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
                    ControlToValidate="FileUpload1" ErrorMessage="File is required"></asp:RequiredFieldValidator>
              <br /><input type="hidden" name="MAX_FILE_SIZE" value="100000" />
              <br />
              <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" 
         Text="Upload File" />          
              &nbsp;<br />
              <br />
              <asp:HiddenField ID="id2" runat="server"   />
              <asp:Label ID="Label1" runat="server"></asp:Label>
            </div>
      </form>

You cannot check the size of the file before it is uploaded to the server. You can only upload to the server if the file is less that the size allowed on server. You would need to use Javascript or other client side technique to achieve this.
