I need to load a lot of data into RADGrid (300,000 rows) . The grid itself seems to handle this nicely, but it takes a while for me to load the data from underlying persistent storage. This results in the grid displaying the loading animation for quite a while, before it actually displays any data.
I would like to load the first 1000 rows or so first (would be very quick), and get that data displayed to the user as fast as possible, and then load the rest of the data in the background. Is this supported ? I am aware that there will be some implications with regards to sorting.
