Hello Harry,

Here is the code snippet that I tried in my application in order to attach client events to RadTextBox/RadComboBox when created dynamically. Give a try with this approach.

CS:

    
            protected void Page_Load(object sender, EventArgs e) 
        
             { 
        
               RadTextBox textbox = new RadTextBox(); 
        
               textbox.ClientEvents.OnValueChanged = "ValueChanged";//attaching client side events 
        
               this.form1.Controls.Add(textbox); 
        
               RadComboBox combo = new RadComboBox(); 
        
               combo.DataTextField = "user_role"; 
        
               combo.DataValueField = "user_role"; 
        
               combo.DataSourceID = "SqlDataSource2"; 
        
               combo.OnClientSelectedIndexChanged = "ClientSelectedIndexChanged";//attaching client side events 
        
               this.form1.Controls.Add(combo); 
        
            }

JAVA SCRIPT:

    
            <script type="text/javascript"> 
        
                function ClientSelectedIndexChanged(sender, args) { 
        
                    alert("ClientSelectedIndexChanged fired"); 
        
                } 
        
                function ValueChanged(sender, args) { 
        
                    alert("ValueChanged fired"); 
        
                } 
        
            </script>
