Finally figured out how to get the code on the master page to deal with this... Would delete this post, but I do not see an option...










I have master page and on this page I have a javascript section that I need to have search the current page to see if a radgrid is on that page.

I tried 
   var control = document.getElementById('<%= RadGridStudents.ClientID %>');
                if (control == null) {
but it returns an error because the grid is not there - of course.



What is the best way in javascript to see if the current page has an element on it before continuing...

   var div, i;
                // Loop through all divs, check if they contain the RadGridStudents
                divs = document.getElementsByTagName('div');
                for (i = 0; i < divs.length; i++) {
                    var rg = divs[i].id;
                    var result = rg.search('RadGridStudents');
                    if (result != -1) {
                        alert(result);
                    }
                    
                }

Hello Warren,

Please take a look at the Getting RadGrid client object help topic to see how the desired functionality can be implemented.

I hope this helps.

Best wishes,
