I am using a radgrid with gridclientselectcolumn with AllowMultiRowSelection="true", the shift key select works however, it selects the rows from the top most selected row till the currently selected row. Say, If I select row 2, then row 4 and then i hold shift and select row 7 it will select all rows from 2 till 7 instead of 2 and 4 to 7
