Asp.net Range Validator


Html (Full Code)

<asp:TextBox ID="txtSasiNo" runat="server" Width="250px" MaxLength="17"></asp:TextBox>
<asp:RegularExpressionValidator CssClass="zorunlu" ValidationGroup="kaskoTeklifSayfasi" Display="Dynamic" ID="rangevalidator1" runat="server" SetFocusOnError="true" ControlToValidate="txtSasiNo" ErrorMessage="Enter number characters only (8 or 17)" ValidationExpression="^\d{8}$|^\d{17}$""></asp:RegularExpressionValidator>

Question:

I am trying to use RangeValidator.

If txtnumber is null or empty and if txtnumber is not 8 characters or not 17 characters. Only 2 options first option is 8 character second option is 17 character.

txtnumber text character only can be like below

12345678    // This is 8 characters
12345678901234567    // This is 17 characters

What to add to RangeValidator in order to achieve this ?

Thanks.


Solution

  • As described by Ondrej you can use RegularExpressionValidator. To be more specific with the aspx. See the code below:-

    UPDATED CODE:

    Here you go:-

    <asp:TextBox ID="txtnumber" runat="server" Width="250px"></asp:TextBox>
    <asp:RegularExpressionValidator Display="Dynamic" ID="regtxt" runat="server" SetFocusOnError="true" ControlToValidate="txtnumber" ErrorMessage="Enter number characters only (8 or 17)" 
        ValidationExpression="^\d{8}$|^\d{17}$"></asp:RegularExpressionValidator>
    

    Hope it helps
