Show checked rows into another DataGridView

Question

I have a DataGridView populated with a DataTable.
I added a CheckBoxColumn to select some rows.

My Goal is to show only se

Answer 1

The problem is the data table DT_Events doesn't have the column Sel, select takes the datasource of the grid i.e the data table you assigned.

Instead of adding a checkboxcolumn, add a boolean column Sel in the table DT_Events and assign to grid.
