Hi TusharZoo,
I assume you have not bound your grid values to a data source?
So you could just handle GridView's
CellEndEdit
Event and than run whatever logic you want (Change the displayed values or the underlaying data source)
dataGridView1.CellEndEdit += dataGridView1_CellEndEdit;
...
void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
var cell = dataGridView1[e.ColumnIndex, e.RowIndex];
cell.Value...
}
}
