The DataGridView control is extremely configurable and extensible; DataGridView provides many properties, methods, and events to modify its look and behavior. The DataGridView control makes it simple to define the basic appearance of cells and the display formatting of cell values. Below I write few line of code for formatting DataGridView appearance in C#.

Write the below code for change your DataGridView appearance

 private void Form1_Load(object sender, EventArgs e)

 {

 dataGridView1.RowsDefaultCellStyle.BackColor = Color.AliceBlue;

 dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.Aqua;

 dataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None;

 dataGridView1.DefaultCellStyle.SelectionBackColor = Color.CadetBlue;

dataGridView1.DefaultCellStyle.SelectionForeColor = Color.White;

 dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;

}

Code description:
