sql = "Select [Available_date],[Session1],[Session2],[Session3],[Session4] from Tb_Faculty_Availability where Faculty_code = '" + cb_Faculty_Code.Text.ToString() + "'";
dr = GFun.ReadAcessSql1(sql);
while (dr.Read())

for (irows = 0; irows < DGVCalendar.RowCount; irows++)
{

DGVCalendar.Rows[irows].Cells[2].Value = dr[0].ToString();
DGVCalendar.Rows[irows].Cells[4].Value = dr[1].ToString();
DGVCalendar.Rows[irows].Cells[5].Value = dr[2].ToString();

}
irows++;

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.
