How to programmatically set cell value in DataGridView?

Question

I have a DataGridView. Some of the cells receive their data from a serial port: I want to shove the data into the cell, and have it update the underlying bound object.

Answer 1

I searched for the solution how I can insert a new row and How to set the individual values of the cells inside it like Excel. I solved with following code:

dataGridView1.ReadOnly = false; //Before modifying, it is required.
dataGridView1.Rows.Add(); //Inserting first row if yet there is no row, first row number is '0'
dataGridView1.Rows[0].Cells[0].Value = "Razib, this is 0,0!"; //Setting the leftmost and topmost cell's value (Not the column header row!)
dataGridView1[1, 0].Value = "This is 0,1!"; //Setting the Second cell of the first row!

Note:

1. Previously I have designed the columns in design mode.
2. I have set the row header visibility to false from property of the datagridview.
3. The last line is important to understand: When yoou directly giving index of datagridview, the first number is cell number, second one is row number! Remember it!

Hope this might help you.
