This way you can format the digits as per your need
protected void Page_Load(object sender, EventArgs e)
{
string constr = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
using (SqlConnection conn = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand("SELECT [Salary] as Price From Person", conn))
{
using (SqlDataAdapter da = new SqlDataAdapter(cmd))
{
DataSet ds = new DataSet();
da.Fill(ds);
lblPrice.Text = Convert.ToDecimal(ds.Tables[0].Rows[0]["Price"]).ToString("N2");
}
}
}
}
