Hi,
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/groupby/defaultcs.aspx
I’m tryingto create a dynamic group by grid and use above sample.
In stead ofusing datasourceid field, I create a dynamic datatable object and bind it withthe grid’ datasource property.
The sampleworks, however each time when I drag and drop a column header into the group byarea.
There isobject null error. Any idea? The source of the data is binded on need dataevent, and I also tried the batabind event as well.

Hello Bin,
If you use advanced binding with NeedDataSource event handling as illustrated on this demo, the grouping feature should work as expected either you define the group expressions declaratively or programmatically from the code-behind. Note that the built-in grouping feature is not supported with simple binding with DataBind() calls.
If you still experience issues, please post your markup and code-behind using the "Format Code Block" dialog of the forum editor. We will examine it in detail and will advice you further.
