Just for fun you can include in your jqGrid treeANode: -2 parameter and reset the parameter treeANode to -2 one more time in the loadComplete:

loadComplete: function(){
    this.p.treeANode=-2;
} 

You will see that the old grid contain will not deleted by jqGrid and new contain will be just appended to the grid on every grid refresh.

It is not the way which I recommend you! It is just for playing. It shows only how the grid work and that the place is the only place where the grid contain will be deleted during refreshing.

If you grid work very slowly you should search for the problem in your code: For example: you don't use gridview:true jqGrid parameter or you use afterInsertRow event handle or you use any very slow actions inside of loadComplete/gridComplete event... I can continue.

Best regards

I'd like to reload a grid with remote data as a background task, but it seems that the grid content is deleted before the ajax request is send.

Is there a simple way to update the grid content once the ajax request is complete,  in order to minimize the 'refreshing' time while the grid is empty ?

Thanks for your help !
