hi,
if your datagrid's column type is DataGridViewCheckBoxColumn then you pass the value by using following code
DGVCalendar.Rows[irows].Cells[2].Value = dr[0].ToString().ToLower() == "true" ? true : false;
DGVCalendar.Rows[irows].Cells[4].Value = dr[1].ToString().ToLower() == "true" ? true : false;
DGVCalendar.Rows[irows].Cells[5].Value = dr[2].ToString().ToLower() == "true" ? true : false;
DGVCalendar.Rows[irows].Cells[6].Value = dr[3].ToString().ToLower() == "true" ? true : false;
DGVCalendar.Rows[irows].Cells[7].Value = dr[4].ToString().ToLower() == "true" ? true : false;
hope this will help you.
