wpf binding and lazy loading

[Kevin Anderson]

I did do a quick search but honestly I am not even sure what to look
for. I am using a grid (XamDataGrid) with nhibernate and it seems that
the wpf binding to the grid is causing load all of the various pieces
of the object each row is displaying even if we have lazy loading on
and the column for that particular piece is not visible.

Has anybody seen this behavior? Is there a work around?

Thanks.

My guess is that you are running a grid which is layout-virtual and not data-virtual. What this means is that the grid will pull all the data from the data source, but not create visuals for non-visible elements.

 

You will likely need to figure out how to virtualize the data access.

Proper way to achieve what you want is to use pagination tech.

But this will require additional coding.

don't bind the grid directly to NH object. map the NH objects to view models and load the view model into the UI control.
