page does not load(only empty blue page shows), have to refresh page to load in IE11 for telric grid

[Mukesh]

We are using the telerik grid control and facing the issue with this. It does not load the lists properly some times it gives us blank page ,once we refresh that page then it works for us.
Page randomly comes blank in case of IE11.
Can you please suggest me on this ?
my code is like this.
if((Request.Browser.Browser == "IE" || Request.Browser.Browser == "InternetExplorer") && (Request.Browser.MajorVersion >=7))
                        {
                            
                            compatibleIEVersion = "9";
                                   
                        }
if I change compatibleIEVersion = "edge"; then it works but creates the issues for drop downs.
Please suggest me on this.
