I have a datagridview with 11 columns and potentially thousands of rows. The user will sometimes need to make graphs from the data. I need to know which cells are selected. Surprisingly, the graph is easier than getting these selected items! Does anyone know how to do this? I would like to have the control/flexibility to know if the user selected the second column and fourth column, second column from cell 2-100 and column and fourth from 400 thru 700. Is this possible? Thanks.
