[VB Programmer]

How do you limit the "Files of Type" selections in the dialog for a
FileUpload control?

FYI: Here's one way...

<asp:RegularExpressionValidator
id="RegularExpressionValidator1" runat="server"
ErrorMessage="Bad file type..."
ValidationExpression="^(([a-zA-Z]|(\\{2}\w+)\$?)(\\(\w[\w].*))+(.mpeg|.MPEG|.wmv|.WMV|.avi|.AVI|.mov|.MOV)$" ControlToValidate="FileUpload1"></asp:RegularExpressionValidator>"VB Programmer" <[email protected]> wrote in messageHow do you limit the "Files of Type" selections in the dialog for aFileUpload control?>
