With large datasets paging seems to crash and doesnt expand child bands. Can someone give me an example of how I can prevent this from happening. DO I need to rebind grid on every postback. How can i call rowIslandsPopulating on demand?
Hi dev_here,
There seems to be a separate thread regarding this matter, please refer to it:

Petar,
Can you give me an example of a manual on demand WHDG inside an updatepanel?
As i am still facing issues in navigation of child bands. cannot seem to be able to page/filter
Well, in my case the grid is not placed in side an updatepanel and I did not find any other way to make it work
Hello dev_here,
Thank you for sharing your solution.
EnableDataViewState may make a difference depending on whether the grid is being rebound on each postback and disabling AJAX may also make a difference if the grid is placed inside an UpdatePanel:

Please do not hesiate to contact me if you have any additional questions.
Finally found the way to get around this:
EnableDataViewState
="True" EnableAjax="False"
Thsi helps in getting data from large datasets with paging.
