how to give default value to gridview ?

Here's another example:

public class Product
{
public int ProductID { get; set; }
public string Make { get; set; }
public string Model { get; set; }
}
private List < Product > GetProducts()
{
List < Product > products = new List < Product > ();
products.Add(new Product {ProductID = 1, Make = "Samsung", Model = "Galaxy S3"});
products.Add(new Product {ProductID = 2, Make = "Samsung", Model = "Galaxy S4"});
products.Add(new Product {ProductID = 3, Make = "Samsung", Model = "Galaxy S5"});
products.Add(new Product {ProductID = 4, Make = "Apple", Model = "iPhone 5"});
products.Add(new Product {ProductID = 5, Make = "Apple", Model = "iPhone 6"});
products.Add(new Product {ProductID = 6, Make = "Apple", Model = "iPhone 6"});
products.Add(new Product {ProductID = 7, Make = "HTC", Model = "Sensation"});
products.Add(new Product {ProductID = 8, Make = "HTC", Model = "Desire"});
products.Add(new Product {ProductID = 9, Make = "HTC", Model = "Desire"});
products.Add(new Product {ProductID = 10, Make = "Nokia", Model = "Lumia 735"});
products.Add(new Product {ProductID = 11, Make = "Nokia", Model = "Lumia 930"});
products.Add(new Product {ProductID = 12, Make = "Nokia", Model = "Lumia 930"});
products.Add(new Product {ProductID = 13, Make = "Sony", Model = "Xperia Z3"});
return products;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GridView1.DataSource = GetProducts();
GridView1.DataBind();
}
}

Hi Subin,
Please go through the below link
https://www.c-sharpcorner.com/uploadfile/1a81c5/display-columns-as-rows-in-gridview-in-asp-net/
DataTable dt = new DataTable();

    //Adding columns

    dt.Columns.Add("Names", typeof(string));

    //Adding Row
    DataRow dr = dt.NewRow();
    dr["Names"] = "Ram";
    dt.Rows.Add(dr);

    dr = dt.NewRow();
    dr["Names"] = "Krishna";
    dt.Rows.Add(dr);

    GridView1.DataSource = dt;
    GridView1.DataBind();
