I have a Master-Detail table in RadGrid. For each row of master, there is a DetailTable which expands/collapse. The Radgrid also has paging (15 rows per page). I am using an external button to ExpandAll rows of the grid. On first page i see all 15 rows expanded, but when i go to Page 2(paging), i need the DetailTables expanded for each row on the 2nd page. Can someone please suggest how would i achieve that?
