To validate a file type or say file extension on client side before you upload a file can be performed by just putting a Regular Expression Validator. Here, i have provided one example to allow uploading only .jpg or .gif files. All you need is a FileUpload control and a Regular Expression Validator to check file type.
<asp:FileUpload ID=”FileUpload1″ runat=”server” /> <asp:RegularExpressionValidator ID=”RegularExpressionValidator1″ runat=”server” ControlToValidate=”FileUpload1″ Display=”Dynamic” ErrorMessage=”Upload a valid file” ValidationExpression=”^.+(.jpg|.JPG|.gif|.GIF)$”></asp:RegularExpressionValidator> If you want to put your own file type validation then just replace “.jpg,.JPG,.gif,.GIF” text, and you can add more file types by adding “|” (pipe) sign and your own file type to validate. source: hspinfo.wordpress.com/2008/06/18/client-side-validation-of-file-type-before-you-upload-a-file/ __________________ |
