Simple GridView Data Binding in ASP.NET

I am going to write a blog on "Gridview Code". This is my first blog on Simple Gridview Data Binding using c#.

Source Code

<div>
    <asp:GridView ID="grdCompany" runat="server">
    </asp:GridView>

</div>

C# Code

protected void Page_Load(object sender, EventArgs e)

{
    if (!IsPostBack)
        bindGridview();
} 

public DataTable getDataTable()

{

   DataTable dt = new DataTable();
    try
    {
        dt = new DataTable();
        dt.Columns.Add("id", typeof(int));
        dt.Columns.Add("company", typeof(string));
        dt.Columns.Add("address", typeof(string));
        dt.Columns.Add("pincode", typeof(string)); 
        dt.Rows.Add(1, "Capgemini", "Vikhroli East, Mumbai", "400 079");
        dt.Rows.Add(2, "TCS", "Tech Park, Bangalore", "560066");
        dt.Rows.Add(3, "Wipro IT", "Guindy, Chennai", "600032");
    }
    catch { throw; }
    return dt;
} 

public void bindGridview()

{
    grdCompany.DataSource = getDataTable();
    grdCompany.DataBind();
}

Code Output
