I came across a performance issue with the RadGrid. I dynamically create buttons for every row in the grid when they are expanded. Every buttons opens up a modal and it doesn't use any information from the grid. My issue is that postback happens and the whole grid is reloaded, even though I add the buttons to RadAjax manager programatically on ItemDataBound and assign them to only update the modal Panel. Has anyone encountered something similar to this? This is hindering my applications performance greatly. Any advice?
