Convert these values into numeric types (integer or decimal) before doing a sum on these values.

Solution 3

Use the cell's Text property and convert it to Integer.

dataGridView5.Rows[2].Cells[i].Value=Convert.ToInt32(dataGridView5.Rows[2].Cells[i].Text)+Convert.ToInt32(dataGridView5.Rows[2].Cells[i-1].Text)

Solution 4

If you are sure about values are numeric and you are using .Net 4 or higher you can use dynamic.

C#

dataGridView5.Rows[2].Cells[i].Value = (dynamic)dataGridView5.Rows[2].Cells[i].Value +(dynamic)dataGridView5.Rows[2].Cells[i - 1].Value;

Solution 1

try below, convert to int ( I assume you have integer values) and take the sum

C#

dataGridView5.Rows[2].Cells[i].Value=Convert.ToInt32(dataGridView5.Rows[2].Cells[i].Value.ToString())+Convert.ToInt32(dataGridView5.Rows[2].Cells[i-1].Value.ToString())
