In order to run this code, you need to replace connectionstring's credentials myServerName\myInstanceName, myDataBase, myUsername, myPassword with yours

using System.Data;   
using System.Data.SqlClient;

string sConnectionString = @"Data Source=myServerName\myInstanceName;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;";

protected void Page_Load(object sender, EventArgs e){
    if(!IsPostBack)
        BindGridView();   
}

private void BindGridView() {             
    DataTable dt = new DataTable();           
    SqlConnection con = null;         

    try {
        string sQuery = "SELECT ID, Name, Salary FROM EmpDetail";

        SqlConnection con = new SqlConnection(sConnectionString);
        con.Open();
        SqlCommand cmd = new SqlCommand(sQuery, con); 
        SqlDataReader sdr = cmd.ExecuteReader();

        dt.Load(sdr);
        Gridview1.DataSource = dt;
        Gridview1.DataBind();
    }
    catch{ }
    finally{
        dt.Dispose();
        con.Close();
    }
}

You could simply use the SqlDataSource. You would move the SqlDataSource from the toolbox where it says Data, SqlDataSource. You would then configure the datasource using the smart tag. Then using the smart tag on the gridview, select the SqlDataSource you placed onto the aspx page. This is really quick and requires little to no coding. http://msdn.microsoft.com/En-us/Library/z72eefad.aspx this will show you a little bit more. Hope this helps you!

<asp:GridView ID="GridView1" runat="server">
</asp:GridView>

protected void Page_Load(object sender, EventArgs e) {
    if (!IsPostBack) {
        bindData();   
    }
}

public void bindData() {
        SqlConnection con=new SqlCponnection(ConnectionStrings);
        SqlDataAdapter da = new SqlDataAdapter("select * from  Your TableName", con);
        DataSet ds = new DataSet();
        try {
            da.Fill(ds, "YourTableName");
            GridView1.DataSource = ds;
            GridView1.DataBind();
        } catch (Exception e) {
           Response.Write( e.Message);
        } finally {
            ds.Dispose();
            da.Dispose();
            con.Dispose();
        }

Try below code according to your scenario

I hope it helps you

protected void GridviewBind ()
{
    using (SqlConnection con = new SqlConnection("Data Source=RapidProgramming;Integrated Security=true;Initial Catalog=RPDB"))
    {
        con.Open();
        SqlCommand cmd = new SqlCommand("Select Name,Salary FROM YOUR TABLE", con);
        SqlDataReader dr = cmd.ExecuteReader();
        GridView1.DataSource = dr;
        GridView1.DataBind();
        con.Close();
    }
}

<asp:GridView ID="GridView1" runat="server" BackColor="White" 
              BorderColor="#3366CC" BorderStyle="None" 
              BorderWidth="1px" CellPadding="4"
              style="text-align: center; margin-left: 409px" Width="350px">
  <FooterStyle BackColor="#99CCCC" ForeColor="#003399" />
  <HeaderStyle BackColor="#003399" Font-Bold="True" ForeColor="#CCCCFF" />
  <PagerStyle BackColor="#99CCCC" ForeColor="#003399" HorizontalAlign="Left" />
  <RowStyle BackColor="White" ForeColor="#003399" />
  <SelectedRowStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" />
  <SortedAscendingCellStyle BackColor="#EDF6F6" />
  <SortedAscendingHeaderStyle BackColor="#0D4AC4" />
  <SortedDescendingCellStyle BackColor="#D6DFDF" />
  <SortedDescendingHeaderStyle BackColor="#002876" />
</asp:GridView>;

try this....

 protected void Page_Load(object sender, EventArgs e)
{
    using (var conn = new SqlConnection(ConfigurationManager.ConnectionStrings["myDB"].ConnectionString))
    {
        SqlCommand cmd = new SqlCommand("select * from Table1", conn);
        conn.Open();
        SqlDataReader dr = cmd.ExecuteReader();
        GridView1.DataSource = dr;
        GridView1.DataBind();
        conn.Close();
    }

}

<div>
    <asp:GridView ID="GridView1" runat="server"></asp:GridView>
</div>
