check this:
The RequiredFieldValidator  is for empty text and
RegularExpressionValidator  is to check for numeric...
If your textbox can accept empty values remove RequireFieldValidator..
Make sure to set ValidationGroupProperty...

Check this for more info: http://quickstarts.asp.net/QuickStartv20/aspnet/doc/validation/default.aspx

<asp:TextBox ID="Txthr" runat="server" ValidationGroup="Txthr1"></asp:TextBox>
      <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
          ControlToValidate="Txthr" ErrorMessage="RequiredFieldValidator"
          ValidationGroup="Txthr1">*</asp:RequiredFieldValidator>
      <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
          ControlToValidate="Txthr" ErrorMessage="RegularExpressionValidator"
          ValidationExpression="^[0-9]*" ValidationGroup="Txthr1">*</asp:RegularExpressionValidator>
      <asp:Button ID="Button2" runat="server" Text="Button" ValidationGroup="Txthr1" />

Regularexpressionvalidator works well, but RequiredFieldValidator no. Appears the error message in all lines of gridview
