Hi
I am creating RadTextBox and RadComboBoc controls dynamically from information stored in a database.
Can you please expalin how I can wire up a client side event as each control is created. I am mainly using the OnValueChanged and OnClientSelectedIndexChanged events, respectively.
Could I have answered this myself from the online help?
Regards

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> 

Regards,
Shinu.

Hi Shinu
Thank you so much for your quick response.
The answer is much simplier than I expected.
I guess to become a master takes time.
