Javascript

    
                    function KeyEnterUserName(sender, eventArgs) {  
        
                        var c = eventArgs.get_keyCode();  
        
                        if (c == 13) {  
        
                            var userNameSearch = document.getElementById('Login1$LoginButton');  
        
                            userNameSearch.click();  
        
                        }  
        
                    }

ASPX

    
            <
 
asp:Login ID="Login1" runat="server" BackColor="#F7F6F3" BorderColor="#E6E2D8" BorderPadding="4"
            
BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana" Font-Size="0.8em"
            
ForeColor="#333333">
            
<
 
LayoutTemplate>
            
            <telerik:RadTextBox ID="UserName" runat="server" Width="136px" ClientEvents-OnKeyPress="KeyEnterUserName" /> 
        
            <asp:Button ID="LoginButton" runat="server" CommandName="Login" Text="Log In" ValidationGroup="Login1" /></
 
asp:Login>
            
</
 
LayoutTemplate>

That's a rough cut and paste but the parts of the form. Everything works okay, just beeps when you press the enter key.

Hello Daniel,

The beep could be caused by two things:

1) The userNameSearch.click(); line triggers a Javascript error, because the client ID of the login button is not Login1$LoginButton and the getElementById method returns null. The correct ID is Login1_LoginButton.

2) submitting the login form as well as the programmatic click of the button triggers a beep, according to the sound settings in the control panel. You should disable the "Start Navigation" sound.

Hello Dimo

I could reproduce the mentioned issue with the code above.
I created a RadNumericTextBox on a test page (no code behind). When I define a value inside the RadNumericTextBox and press the enter key, I hear a beep and then the page is submitted.
When I use a RadCombobox and carry out the same actions I don't hear anything, just submit.

Hi Dimo

I search the internet and found different results for the same problem. I can disable the beep on my computer but that is not exactly the way to go, in my opinion. Other users will hear tyhe beep also.
I extended the code with the following:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeFile="test2.aspx.cs" Inherits="test2" %> 
        
            <!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></title>  
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                <asp:ScriptManager ID="ScriptManager1" runat="server">  
        
                </asp:ScriptManager> 
        
                <div> 
        
                    <telerik:RadTextBox ID="txtCommentsInput" runat="server" AutoPostBack="True">  
        
                    </telerik:RadTextBox> 
        
                    <br /> 
        
                    <telerik:RadNumericTextBox ID="RadNumericTextBox1" AllowOutOfRangeAutoCorrect="false" 
        
                        runat="server" Type="Number" AutoPostBack="true" Visible="true">  
        
                        <NumberFormat AllowRounding="true" KeepNotRoundedValue="false" DecimalDigits="0" /> 
        
                    </telerik:RadNumericTextBox> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

When I enter text in the RadTextBox I hear the beep after first submit. When I submit the second time without changing the value I don't hear a beep anymore. When I change the value again and submit I hear a beep again.
In the RadNumerixTextbox I hear a beep after each submit with or without changing the value.

When I put this in the codebehind:

    
            using System;  
        
            public partial class test2 : System.Web.UI.Page  
        
            {  
        
                protected void Page_Load(object sender, EventArgs e)  
        
                {  
        
                    txtCommentsInput.Attributes.Add("onkeydown", "if(event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {form.submit();return false;}} else {return true}; ");  
        
                }  
        
            }

I don't hear any beeps anymore.

regards
Luc

Hello Luc,

This device is enabled and running on my PC and still no beeps when using RadNumericTextBox. Probably something else is involved as well?

On a side note, eventhough we still do not know the exact cause of the problem, I doubt that we can do anything about it from the control's code. The only sound that I can get from a RadNumericTextBox is when I enable the "Start Navigation" sound from the Control Panel and the control posts back automatically when its value is changed. However, this is normal.

Kind regards,
Dimo
