Allow User to Upload only .doc file


check this example with server side :

if (FileUpload1.HasFile == true && FileUpload1.PostedFile != null)
        {
            int _size = 9437184;// equal 9 mb
            string _fileExt = System.IO.Path.GetExtension(FileUpload1.FileName);
            if (_fileExt.ToLower() == ".doc" || _fileExt.ToLower() == ".docx" )
            {
                if (FileUpload1.PostedFile.ContentLength <= _size)
                {
                    string CarFile = Guid.NewGuid().ToString() + Path.GetExtension(FileUpload1.FileName);
                    FileUpload1.SaveAs(Request.PhysicalApplicationPath + "Car_Image\" + CarFile);                    

                }
                else
                {
                    FileUpload1.Focus();
                    ClientScript.RegisterStartupScript(Type.GetType("System.String"), "messagebox", "<script type="text/javascript">alert('Max file size is 9 m.b');</script>");
                }
            }
            else
            {
                FileUpload1.Focus();
                ClientScript.RegisterStartupScript(Type.GetType("System.String"), "messagebox", "<script type="text/javascript">alert('Only doc or docx are allowed');</script>");
            }
        }
        else
        {
            //-- if person not has image set default  for him
            

        }

 Or try this using Validator Control:

try this example to allow user to upload file with Doc extension

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
                    ErrorMessage="Only JPG/jpg file allowed!"
                    ControlToValidate="ctlFileUpload"
                    ValidationExpression="^(([a-zA-Z]: )|(<a>\{2}w+)$?)(\(w[w](.)*))+(.doc|.DOC)$</a>"
                    Width="510px" CssClass="Validator"></asp:RegularExpressionValidator>

//—–or —–

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
                    ErrorMessage="Only doc file allowed!"
                    ControlToValidate="ctlFileUpload"
                    ValidationExpression="^(([a-zA-Z]: )|(<a>\{2}w+)$?)(\(w[w].*))+(.doc|.DOC)$</a>"
                    Width="510px" CssClass="Validator"></asp:RegularExpressionValidator> 

//——-or ——-

  <asp:RegularExpressionValidator ID="imgValidator" runat="server" ControlToValidate="imgUpload"
                ErrorMessage="*doc files only" ValidationExpression="^.+.(([dD][oO][cC]?[xX])|([dD][oO][cC]))$" />

or try this to allow user to upload doc file

<asp:RegularExpressionValidator ID="FileUpLoadValidator" runat="server" ErrorMessage="Only doc files!"
                ValidationExpression=".*(.doc|.DOC)$" ControlToValidate="FileUpload1" Display="None">

//—— or ———

<asp:RegularExpressionValidator ID="FileUpLoadValidator" runat="server" ErrorMessage="Only .doc files!"
                ValidationExpression=".*(\.doc|\.DOC)$" ControlToValidate="FileUpload1" Display="None">

Hope it helps you

Good Luck
