Dear Telerik Team,

I have a page with RadGrid control which has some bound columns and GridButton column which is for delete (having inner) item in grid. Open a popup when click on command item link button and it has a tabstrip which has three tabs. In third tab we have a grid which has to ask radconfirm on OnClient event when click on Generate command item Link button. If OK it has to fire event and do some operation. I tried with all the ways from the articles,forum and documentation source but i didn't. At last i tried with the below script which is working fine but i am unable to fire Delete in Grid.

<script language="javascript" type="text/javascript">     
        var oldConfirm = radconfirm;        
        window.radconfirm = function(text, mozEvent, oWidth, oHeight, callerObj, oTitle)        
        {        
            var ev = mozEvent ? mozEvent : window.event; //Moz support requires passing the event argument manually        
            //Cancel the event        
            ev.cancelBubble = true;        
            ev.returnValue = false;        
            if (ev.stopPropagation) ev.stopPropagation();        
            if (ev.preventDefault) ev.preventDefault();        
                    
            //Determine who is the caller        
            var callerObj = ev.srcElement ? ev.srcElement : ev.target;        
       
            //Call the original radconfirm and pass it all necessary parameters        
            if (callerObj)         
            {        
                //Show the confirm, then when it is closing, if returned value was true, automatically call the caller's click method again.        
                var callBackFn = function (arg)        
                {                   
                    if (arg)        
                    {                   
                        callerObj["onclick"] = "";                  
                        if (callerObj.click) callerObj.click(); //Works fine every time in IE, but does not work for links in Moz        
                        else if (callerObj.tagName == "A") //We assume it is a link button!        
                        {                                                               
                            try       
                            {        
                                eval(callerObj.href)        
                            }        
                            catch(e){}        
                        }        
                    }        
                }        
    
                oldConfirm(text, callBackFn, oWidth, oHeight, callerObj, oTitle);      
            }        
            return false;        
        }       
    </script>   
Can you please go through this issue and give me a better solution.

Hi Pradeep,

The "blocking radconfirm" logic that you posted works in certain scenarios only. What I would suggest in your case is to use the original radconfirm() function - you could use the client callback function to fire a custom command for the grid.
e.g. in the client callback function:
$find("<%=RadGrid1.ClientID%>").get_masterTableView().fireCommand("MyCustomCommand",itemIndex);
Then, in the RadGrid.CommandItem event handler, you can executed different code based on the received ArgumentName.



Sincerely yours,
