how to sum the integers in the i,j cells in data grid view
dear sir,
I have 2 problems that bothering me too much.
1. firstly, how to sum the integers in the cells from the cells of datagridview[0,0]. value to datagridview [jcols,irows].value.
2. secondly, how to multiply the integers in the cell of datagridview[0,0] to datagridview[jcols,irows].value
I paste my codes in here....
please someone help me...
public void acces1()
{
dataGridView2.Columns.Clear();
for (int i = 0; i <= dataGridView1.Rows.Count - 1; i++)
{
string aa;
aa = Convert.ToString(dataGridView1.Rows[i].Cells[1].Value);
dataGridView2.Columns.Add(aa, aa);
dataGridView2.Rows.Add(aa);
}
foreach (DataGridViewRow k in this.dataGridView2.Rows)
{
k.HeaderCell.Value = dataGridView2.Rows[k.Index].Cells[0].Value;
dataGridView2.AutoResizeRowHeadersWidth(DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders);
}
public void calc1()
{
int a, b, c;
int l = dataGridView2.Rows.Count - 1;
for (int i = 0; i <= dataGridView2.RowCount - 1;i++ )
{
for (a = 0; a <= dataGridView2.ColumnCount - 2; a++)
{
if (dataGridView2.Rows[i].Index != -1)
{
b = 0;
b= Convert.ToInt32(dataGridView2.Rows[i].Cells[0].Value.ToString());
c = Convert.ToInt32(dataGridView2.Rows[l].Cells[0].Value.ToString());
c = c + b;
dataGridView2.Rows[l].Cells[0].Value =c;
}
else
{
MessageBox.Show("huh!Please Tell me!");
}
}
