I would like to know how to expand all the data programatically? We have hundred of rows and we want to add a button to expand the data before exporting.
I would also like to know if you have a working MVC5 Sample. The sample installed is not working with Visual Studio 2015.
You can expand rows and columns by configuring member choise filter. Unfortunately we don't provide any other way.
Our MVC example is currently not working and we will fix it in closest release.
