I've run into an interesting issue and hoping someone can shed some light.

I have a radNumericTextBox that has its value being validated and changed if invalid via set_textboxvalue function. The set_textboxvalue is working fine, however I found that if you click back in the textbox the value will return to what it was originally. What's causing this?

Using version 2008.1.515.20

    
            <%@ Page Language="VB" AutoEventWireup="false" CodeFile="sandbox.aspx.vb" Inherits="test_sandbox" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title>Untitled Page</title> 
        
                <script> 
        
                function update() { 
        
                $find('radTbQty').set_textBoxValue('1000'); 
        
                } 
        
                </script> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                    <rad:RadScriptManager ID="RadScriptManager1" runat="server"> 
        
                    </rad:RadScriptManager> 
        
                    <rad:RadNumericTextBox ID="radTbQty" CssClass="txtbox" Width="30px" MinValue="1" 
        
                        MaxValue="4000" MaxLength="4" NumberFormat-DecimalDigits="0" Value="1" runat="server"> 
        
                    </rad:RadNumericTextBox> 
        
                    <a href="#" onclick="update()">Update</a> 
        
                </form> 
        
            </body> 
        
            </html>

Hello Nik,

Simply put, RadInput textboxes consist of two textboxes - one holds the formatted visible value and one holds the actual nonformatted value. The control works correctly when both textboxes have consistent values. You should always use set_value() to set the control's value, as it updates both the visible and the hidden textbox.
