In the fourth position I have stored an Image and it is stored as "Binary data".

I want to view that "Binary data" stored in an SQL Database in a Gridview.

How do I do that?

No error codes the image column does not even display.

string connStr2 = ConfigurationManager.ConnectionStrings["ImageMDFdb"].ConnectionString;
string cmdStr2 = "SELECT * FROM [ImageTable];";
byte[] btImage = null;
DataSet ds = new DataSet();
try
{
    using (SqlConnection conn2 = new SqlConnection(connStr2))
    {
        using (SqlCommand cmd2 = new SqlCommand(cmdStr2, conn2))
        {
            conn2.Open();
            using (SqlDataAdapter da = new SqlDataAdapter(cmd2))
            {
                da.Fill(ds);
                btImage = (byte[])ds.Tables[0].Rows[0][3];
                GridView1.DataSource = ds;
                GridView1.DataBind();
            }
            conn2.Close();
            cmd2.Dispose();
            conn2.Dispose();
        }
    }
}
catch (Exception ex)
{
    Label2.Text = "Gridview: " + ex.ToString();
}
