Submitted by janobe on Tuesday, April 30, 2019 - 19:12.

This time, I’m going to teach you how to add multiple columns and rows in the Datagridview programmatically using C#. This method will illustrate on how to control the columns and rows by creating it manually inside the datagridview. This is a big help for you when you are a beginner in programming.

Creating an Application

Step 1

Open Microsoft Visual Studio 2015 and create a new windows form application in C#. ps1

Step 2

Do the form just like shown below. ps2

Step 3

Press F7 to open the code editor. In the code editor, create a method for adding multiple columns and rows in the datagridview

 
        private void add_Columns_Rows()
        {
            //setup the columns to be added.
            dataGridView1.ColumnCount = 5;
            //Set the columns name
            dataGridView1.Columns[0].Name = "ID";
            dataGridView1.Columns[1].Name = "Item";
            dataGridView1.Columns[2].Name = "Price";
            dataGridView1.Columns[3].Name = "Quantity";
            dataGridView1.Columns[4].Name = "Sub-Total";
 
            //Set a value to be added in a row
            string[] row = new string[] { "1", "Cellphone", "15,000", "2", "30,000" };
            //adding rows in the datagridview
            dataGridView1.Rows.Add(row);
            //Set a value to be added in a row
            row = new string[] { "2", "Laptop", "21,000", "1", "21,000" };
            //adding rows in the datagridview
            dataGridView1.Rows.Add(row);
            //Set a value to be added in a row
            row = new string[] { "3", "Speaker", "2,000", "2", "4,000" };
            //adding rows in the datagridview
            dataGridView1.Rows.Add(row);
            //Set a value to be added in a row
            row = new string[] { "4", "Desktop Computer", "10,000", "5", "50,000" };
            //adding rows in the datagridview
            dataGridView1.Rows.Add(row);
        }

Step 4

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

 
        private void Form1_Load(object sender, EventArgs e)
        {
            //displaying the columns and rows.
            add_Columns_Rows();
        }
