Hi,

I try to validate two RadNumericTextBox control by CompareValidator:

    
            <telerik:RadNumericTextBox id="NumberMinValueTextBox" runat="server" /> 
        
            <telerik:RadNumericTextBox id="NumberMaxValueTextBox" runat="server" /> 
        
            <asp:CompareValidator ID="NumberMinMaxValidator" runat="server" ErrorMessage="The max value couldn't be less than the min value." Operator="GreaterThanEqual" ControlToCompare="NumberMinValueTextBox" ControlToValidate="NumberMaxValueTextBox" ValidationGroup="NumberField" Display="Dynamic" />

It works ok only, when the compared values in the both min and max control contain the same number of digits.
(i.e min = 1, max = 9 or min = 10, max = 25 etc.)

But when I enter e.g. '12' to min control and '102' validation failed. It looks that the max value is trimmed from '102' to '10' then 12 > 10 and validatio failed.

What am I doing wrong? Thanks in advance.

Hello Michal,

I also experienced same issue when tried your code. I achieved same functionality by using CustomValidator instead of CompareValidator. Here is the code that I tried. Hope this helps.

ASPX:

    
            <telerik:RadNumericTextBox ID="NumberMinValueTextBox" runat="server" /> 
        
            <telerik:RadNumericTextBox ID="NumberMaxValueTextBox" runat="server" /> 
        
            <asp:CustomValidator ID="CustomValidator1" ControlToValidate="NumberMaxValueTextBox" 
        
                runat="server" ClientValidationFunction="ClientValidate" ErrorMessage="The max value couldn't be less than the min value."> 
        
            </asp:CustomValidator>

JavaScript:

    
            <script type="text/javascript"> 
        
                function ClientValidate(source, arguments) { 
        
                    var min = $find('<%= NumberMinValueTextBox.ClientID %>'); 
        
                    var max = $find('<%= NumberMaxValueTextBox.ClientID %>'); 
        
                    if (min.get_value() > max.get_value()) { 
        
                        arguments.IsValid = false; 
        
                    } 
        
                } 
        
            </script>

Hi,

Here is sample:

                    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" Culture="auto" UICulture="auto" %>         
                     
            <%@ Register assembly="Telerik.Web.UI, Version=2010.1.519.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" namespace="Telerik.Web.UI" tagprefix="telerik" %>

            </head>         
            <body>         
                <form id="form1" runat="server">         
                <div>         
                         
                <asp:ScriptManager ID="ScriptManager1" runat="server">         
                </asp:ScriptManager>         
                    <telerik:RadNumericTextBox ID="RadNumericTextBox2" Runat="server">         
                        <NumberFormat DecimalSeparator="," DecimalDigits="2" />         
                    </telerik:RadNumericTextBox>         
                    <telerik:RadNumericTextBox ID="RadNumericTextBox1" Runat="server">         
                        <NumberFormat DecimalSeparator="," DecimalDigits="2" />         
                    </telerik:RadNumericTextBox>         
                    <asp:CompareValidator ID="CompareValidator1" runat="server" ControlToValidate="RadNumericTextBox2" ControlToCompare="RadNumericTextBox1" Operator="LessThan" Type="Double"         
                        ErrorMessage="CompareValidator"></asp:CompareValidator>         
                </div>         
                </form>         
            </body>         
            </html>         

and codebehind

                    public partial class _Default : System.Web.UI.Page         
            {         
                protected void Page_Load(object sender, EventArgs e)         
                {         
                    System.Globalization.CultureInfo info = System.Globalization.CultureInfo.CreateSpecificCulture("en");         
                     
                    System.Threading.Thread.CurrentThread.CurrentUICulture = info;         
                    System.Threading.Thread.CurrentThread.CurrentCulture = info;         
                     
                }         
            }         

Notice that a user's culture is set up to english (bescause all of the resource have to be displayed in English language), but there are some customizable fields that could have a comma as separator.

Hi Michal,

The provided sample page works as expected on my side. I tested in Firefox and Internet Explorer. See the attached screeshot.

<%@ Page Language="C#" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<script runat="server">

protected void Page_Load(object sender, EventArgs e)

{

System.Globalization.CultureInfo info = System.Globalization.CultureInfo.CreateSpecificCulture("en");

System.Threading.Thread.CurrentThread.CurrentUICulture = info;

System.Threading.Thread.CurrentThread.CurrentCulture = info;

}

</script>
