Hi Abhilash,

I have created a sample RadGrid web site to demonstrate how you could achieve the requested functionality. Please check out the attached application and let me know if it helps you.

function alertCallBackFn(arg) {
                
               if (arg == true) {
                   var checkBoxes = $("input[id*='chkSelectAllType']");
                   if (checkBoxes.length > 0) {
                       checkBoxes.get(0).checked = true;
                   }
                    
               }
           }
protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
   {
       dynamic data = new[] {
               new { ID = 1, Name ="Name1",path="1.jpg"},
               new { ID = 2, Name = "Name2",path="2.jpg"},
               new { ID = 3, Name = "Name3",path="3.jpg"},
                new { ID = 4, Name = "Name4",path="2.jpg"},
               new { ID = 5, Name = "Name5",path="3.jpg"}
           };
       RadGrid1.DataSource = data;
   }



Please do not forget to add jquery in your page.
