I am using Telerik version 2011.
I have created RadGrid header by using the below code. Under Each header there are sub headers. Each Sub Header is a Rad Grid Column. Each column having Filter Column. Whenever I click on filter button throwing a error in Visual Studio with popup message "Microsoft JScript runtime error: '_data' is null or not an object"
GridHeaderItem newSubHeaderItem = new GridHeaderItem(FuelSummaryGrid.MasterTableView, 0, 0);
newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = " ", BackColor = System.Drawing.Color.FromName("#61AAE6") });
newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = " ", BackColor = System.Drawing.Color.FromName("#61AAE6") });
newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = Driving, ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });
newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = Shift, ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });
newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = Day, ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });
newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = Week, ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });
head.Controls.AddAt(0, newSubHeaderItem);
For the reference please find the images.
Please help me how to resolve this issue.

Hi Sarath,
Could I kindly ask you to elaborate a bit more on your scenario? Which RadGrid event is used for adding the mentioned header items? How the RadGrid is bind and also is it programmatically created? It will be best if you could open a regular support ticket and send us sample runnable application which demonstrates the mentioned issue.
Thus we will be able to debug it locally and advise you further.

Hi Sarath,
I tried to replicate the described issue locally, using your approach for creating Header Item programmatically and was not bale to replicate the mentioned error on filtering. see my test movie below which presents the correct functionality of this scenario:

In such case it will be best if you could open a regular support ticket and send us sample runnable application which demonstrates the mentioned issue. Thus we will be able to replicate it locally and advise you further.

Hi Maria,
Thanks for your response.
What we are facing the problem was from 5th column on wards by clicking any Filter column up to 10th columns We are getting the error "Microsoft JScript runtime error: '_data' is null or not an object" (For first four columns filter column working properly). If you don't mind can you create few more columns in your solution under different headers (Totally 6 to 7 columns in Rad Grid) then you can check the error whether you are getting or not :-)
I have attached my UI screen shot.
Thanks for your patience!!!

Hi Sarath,
I tested the application by applying your recommendation and was able to replicate the issue locally. However after further discussing the issue with our development team it appears that this kind of adding header items to the RadGrid control is not supported scenario. You cold modify the current available column headers but adding spanned new header items in the header table would break the RadGrid functionality.
However I would suggest you to use the MultiColumn Headers feature which the RadGrid provides in order to achieve the required functionality. see the online resources below for more information on this feature and verify if it helps:
