13. //Set a value to be added in a row
    
14. string
    
    [

16. dataGridView1.
    
    Rows
    
    .
    
    Add

    .
    
    Add
    
    (
    
    row)
    
    ;
    
21. //Set a value to be added in a row
    
22. row =
    
    new

    , "2"
    
    , "4,000"
    
    }
    
    ;
    
23. //adding rows in the datagridview
    
24. dataGridView1.
    
    Rows
    
    .
    
    Add
    
    (
    
    row)
    
    ;
    
25. //Set a value to be added in a row
    
26. row =
    
    new
    
    string
    
    [
    
    ]
    
    {
    
    "4"
    
    , "Desktop Computer"
    
    , "10,000"
    
    , "5"
    
    , "50,000"
    
    }
    
    ;
    
27. //adding rows in the datagridview
    
28. dataGridView1.
    
    Rows
    
    .
    
    Add
    
    (
    
    row)
    
    ;
    
29. }

Do the following codes to execute the method that you have created in the first load of the form.

1. 
   
2. private
   
   void
   
   Form1_Load(
   
   object
   
   sender, EventArgs e)
   
3. {
