I just took your declaration, put it onto one of my pages, and it worked fine for me. Does the control have focus on initial load?.If so, the text will not be visible as it disappears with focus and will appear if focus is not on the control and the control is empty. This is so that when you click in a textbox the box will be empty for your user data input.

One other non-related thing, you may not need your onfocus declaration as the control has one built-in. Try changing onfocus="movetoend()" to be:

    
            <telerik:RadTextBox ID="RadTextBoxName" runat="server" TabIndex="4" SelectionOnFocus="CaretToEnd" 
        
                    Width="175px" ForeColor="#898a8c" Font-Names="Tahoma" Font-Size="12pt" Height="16px" EmptyMessage="Name"> 
        
                </telerik:RadTextBox>

Hello Anumeha,

Having an empty message visible inside a focused textbox is not a very good idea, because this means that the textbox will hold a value, which is not real. You will have to take care of removing and adding the fake value and make sure that it is not treated like a real value. That's why I recommend avoiding such a scenario. Like Steve suggested, you can use a regular EmptyMessage, no matter whether you focus the textbox initially or not. Another way to tell the user what to type in the textbox is to use the RadTextBox' Label.

If you still insist on implementing the desired behavior, here is a hint:

    
            <%@ 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) 
        
                { 
        
                    if (RadTextBox1.Text == String.Empty) 
        
                    { 
        
                        RadTextBox1.Text = "type here"; 
        
                    } 
        
                    RadTextBox1.Focus(); 
        
                } 
        
            </script>

            <script type="text/javascript">

                    EmptyValueFlag = true; 
        
                    args.set_cancel(true); 
        
                    sender.set_value(args.get_keyCharacter()); 
        
                }    
        
            } 
        
            </script>
