Just check extension before uploading.

C#

if (FileUpload1.HasFile)
        {
            // Get the name of the file to upload.
            string fileName = Server.HtmlEncode(FileUpload1.FileName);
            // Get the extension of the uploaded file.
            string extension = System.IO.Path.GetExtension(fileName);
            // Allow only files with .doc or .xls extensions
            // to be uploaded.
            if (extension == ".pdf") 
{
//upload accordingly
}
            }

Use FileUpload control &RegularExpressionValidator to validate.

XML

<asp:FileUpload ID="flUpld" runat="server" />

                <asp:RegularExpressionValidator
                    id="RegularExpressionValidator1" runat="server"
                    ErrorMessage="Only PDF files are allowed!"
                    ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))(.pdf|.PDF)$"
                    ControlToValidate="flUpld" CssClass="text-red"></asp:RegularExpressionValidator>
