I am trying to figure out how to access the value of the selected item in a combo box on the client side. I am trying to do this from inside another javascript function where I am building an array of the information on the screen.

All of the examples I have found so far show assigning the value during an event firing. I need to find the value outside of one fo the combobox events firing. If I were using an HTML dropdown I wold just ask for the control.value. But when I try that with the telerik control I get the text of the selected item rather than the assigned value of the selected item. I have been unsuccessful in figuring this out from the help file. Can someone point me to a place that explains how to do this simple task?

The following worked for me:

    
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head id="Head1" runat="server"> 
        
                <title>Test</title> 
        
                    <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server"> 
        
                    <script type="text/javascript"> 
        
                        function OnLoad(sender, args) { 
        
                            var comboBox = sender; 
        
                            var itemValue = comboBox.get_value(); 
        
                            alert(itemValue); 
        
                        } 
        
                    </script> 
        
                    </telerik:RadCodeBlock> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                    <div> 
        
                        <asp:ScriptManager ID="ScriptManager" runat="server"> 
        
                        </asp:ScriptManager> 
        
                        <telerik:RadComboBox ID="RadComboBox1" runat="server" Width="160px" OnClientLoad="OnLoad"> 
        
                            <Items> 
        
                                <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1"  
        
                                    Value="myItemValue" /> 
        
                            </Items> 
        
                        </telerik:RadComboBox> 
        
                    </div> 
        
                </form> 
        
            </body> 
        
            </html>

I think what you were looking for was the get_value() function that is offered on the client-side. You can get more information on other functions to use on a RadComboBox object by looking into this documentation article :)
