Hello Rose Garza,

Here is one solution:

Declare a global javascript variable which will store the currently clicked toolbar item - this will happen in OnClientItemClicked event for example. Then in the OnRequestStart event handler you can access the global javascript variable.
Here is a sample code:

    
            <script type="text/javascript"> 
        
            //global variable holding the last clicked item 
        
            var clickedItem; 
        
            function OnRequestStartHandler(sender, eventArgs) 
        
            { 
        
                if (clickedItem) 
        
                { 
        
                    alert(clickedItem.get_text()); 
        
                }    
        
            } 
        
            function OnClientButtonClickedHandler(sender, eventArgs) 
        
            { 
        
                //initialize the clickedItem var     
        
                clickedItem = eventArgs.get_item(); 
        
            } 
        
            </script>

I hope this helps.

Hi,

OnClientButtonClicked and OnClientButtonClicking did not work for me. I have the following code, please check the same in IE and firefox. The client side click event of the toolbar button should be called first and then OnRequestStart of the Ajax, but it happens reverse in case of Firefox.

The code is,

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %> 
        
            <%@ Register Assembly="RadToolbar.Net2" Namespace="Telerik.WebControls" TagPrefix="radTlb" %> 
        
            <%@ Register Assembly="RadAjax.Net2" Namespace="Telerik.WebControls" TagPrefix="radA" %> 
        
            <%@ Register Assembly="RadSplitter.Net2" Namespace="Telerik.WebControls" TagPrefix="radspl" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

                    function click_more()  
        
                    {  
        
                        alert('click_more');  
        
                        return false;  
        
                    }  
        
                    function Defaul_click()

                    {  
        
                        alert(eventArgs.EventTarget);  
        
                    }

            </body> 
        
            </html>

and the code behind is,

    
            using System;  
        
            using System.Data;  
        
            using System.Configuration;  
        
            using System.Collections;  
        
            using System.Web;  
        
            using System.Web.Security;  
        
            using System.Web.UI;  
        
            using System.Web.UI.WebControls;  
        
            using System.Web.UI.WebControls.WebParts;  
        
            using System.Web.UI.HtmlControls;  
        
            public partial class Default2 : System.Web.UI.Page  
        
            {  
        
                protected void Page_Load(object sender, EventArgs e)  
        
                {  
        
                    //Telerik.WebControls.RadToolbarButton tbBtnMore =  
        
                    //   tbrButtons.Items.GetButtonByCommandName("More");  
        
                    //tbBtnMore.Attributes.Add("onClick", "if(!click_more()){return false;}");  
        
                }  
        
            }

Let me what is going wrong?

Thanks.
