You don't posted the definition of the grid which you use, so some questions for me stay opened. Nevertheless I hope that you will find the answer on your question here . In the demo included in the answer are used the parameter loadonce:true which makes all more complex.
The rows which will be selected are not on the first page of the loaded data. Moreover, in the demo there are no columns (even hidden) which can be used to determine which rows should be selected. Instead of that the information about the selection in the grid will be sent from the server as a part of userdata part of the JSON response.
This way is more general and I hope it will work also in your grid.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
