You can use DateDiff function to calculate the difference between any two date and time values.

Example

DateDiff("d", [FirstDate], [SecondDate]) //Displays the days between the values of the FirstDate and SecondDate fields.
The firstdate and second date will be a DateTime...

Or you can have a look to this site

You can try using DataSet, like, take all the values from the datagridview in the dataset and after that using the columns of startdate and enddate, update the presentdays column. 

DataSet ds= ((DataTable)datagrid1.dataSource).DataSet

Like this you will get all the columns in the dataset 

private void Columns(DataSet ds)

{

    foreach(DataTable table in ds.Tables)

    {

        foreach(DataColumn c in table.Columns)

        {

            Console.WriteLine(c.ColumnName);

        }

    }

}
