I have a little issue with selecting all rows in datagridview.

Ok, I have a datagridview with 20 visible columns, and 10 invisible (for program purposes I made those invisible)

and I have a button with


and that works fine when datagridview is populated with 50 rows, but as the number of populated rows gets up, so the the time to select all those rows on button click gets also higher. until around 3500 rows when it simplY crashes down.
now I have tried with selectionmode to change to CellSelect and that works fine but the thing is when you change to CellSelect then rows arent selected which I need in further work of my application. so I figured there is some problem with those inivisible columns

Solutions, most welcome :)

It means the code is executing to select the cells doing some extensive tasks. double check is there any extensive operation inside the datagrid.SelectionChanged event or cellSelection changed event.

do some trail and error method by removing all the datagrid event subscription and apply select all. normally it shouldnt take too much time just to select the cells
