Question

i have datagridview with values 0; 11,4; 2,3….. ;

How can i add values for example from two cells and send it to third cell?

            dataGridView1[3, 0].Value = Convert.ToInt16(dataGridView1[1, 0].Value) + Convert.ToInt16( dataGridView1[2,0].Value);

but this doesn’t work

so for example in next cell i’ll have 11,4+2,3=13,7.

Problem is in adding float values from datagridview cells.

Answer 1

Why you convert to INT, when you have float? Try use this

dataGridView1[3, 0].Value = Convert.ToDouble(dataGridView1[1, 0].Value) + Convert.ToDouble(dataGridView1[2, 0].Value);
