i have a datetime field in a gridview
i need the date field to be null or empty if the database returns either null, “”, or 1/1/0001

how does one achieve this– i seem to be having a brain freeze.

you can see what i have tried below

   <asp:TemplateField HeaderText="LastEval" ItemStyle-CssClass="gvColumnSmallCss">
                        <ItemTemplate >
                        <asp:Label ID="lblmyLabel"  Text='<%# Bind("myField","{0:M/d/yyyy}") %>'  runat="server" > </asp:Label>  
                            
                        <%--    Text= '  <%#  Eval("myField") !=null ? Convert.ToDateTime(Eval("myField")).ToString("MM/dd/yyyy") : "" %>'
                      --%>
                            
                       
                              
                           <%-- Text='<%# Bind("myField","{0:M/d/yyyy}") %>'--%>
                        </ItemTemplate>

c#

 protected void gv_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                string myField;
                myField= (e.Row.FindControl("lblmyField") as Label).Text;
                DateTime? myField= null;
                _myField = string.IsNullOrEmpty(myField)
                 ? (DateTime?)null : (DateTime?)DateTime.Parse(myField);

                DateTime checkDate = DateTime.Parse("1/1/00001");


                if (lastEval == checkDate.ToString() || myField=="")
                {
                    (e.Row.FindControl("lblmyField") as Label).Text = "";

                }
             
            }
        }
