How to Add Columns and Rows in the Datagridview in C#

This time, I’m going to teach you how to add columns and rows in the Datagridview programmatically using C#.Net. This is a step by step guide and easy to follow for adding columns and rows in the Datgridview. I will use Microsoft Visual Studio 2008 for my IDE

So, let gets started.

Step 1. Open Microsoft Visual Studio 2008 and Create a new windows form application.

Step 2. Add a Label and a Datagridview in the Form. See the figure1 as follows.

Figure 1.

Step 3. Double-click the Form and do the following codes for adding Columns and Rows in the Datagridview.

 //Setting up columns to be added.
 dataGridView1.ColumnCount = 5;
 //Set the columns name
 dataGridView1.Columns[0].Name = "ID";
 dataGridView1.Columns[1].Name = "Product";
 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", "Product 1", "500", "2", "1,000" };
 //adding row
 dataGridView1.Rows.Add(row);
 //Set a value to be added in a row
 row = new string[] { "2", "Product 2", "1,000", "3", "3,000" };
 //adding row
 dataGridView1.Rows.Add(row);
 //Set a value to be added in a row
 row = new string[] { "3", "Product 3", "2,000", "4", "8,000" };
 //adding row
 dataGridView1.Rows.Add(row);
 //Set a value to be added in a row
 row = new string[] { "4", "Product 4", "3,000", "5", "15,000" };
 //adding row
 dataGridView1.Rows.Add(row);
