试试这个会对你有用：

if (CheckBox1.Checked == false)
{
    String strConnString = ConfigurationManager.ConnectionStrings["CallcenterConnectionString"].ConnectionString;
    SqlConnection con = new SqlConnection(strConnString);
    SqlCommand cmd = new SqlCommand("insert into CallCenter..Loy_DispMstr (CallType, SUBFormat, Disposition, SubDisposition) values (@CallType, @Format, @Disposition, @SubDisposition)", con);
    cmd.Parameters.Add("@CallType", ddlCalltype.SelectedItem.Value);
    cmd.Parameters.Add("@Format", ddlFormat.SelectedItem.Value);
    cmd.Parameters.Add("@Disposition", ddlDisp.SelectedItem.Value);
    cmd.Parameters.Add("@SubDisposition", ddlSubdisp.SelectedItem.Value);
    con.Open();
    int i = cmd.ExecuteNonQuery();
    con.Close();
    Label2.Text = " Your data is been saved in the database";
    Label2.ForeColor = System.Drawing.Color.ForestGreen;

}
else if (flag == 0 && CheckBox1.Checked == true)
{
    String strConnString = ConfigurationManager.ConnectionStrings["CallcenterConnectionString"].ConnectionString;
    SqlConnection con = new SqlConnection(strConnString);
    SqlCommand cmd = new SqlCommand("insert into CallCenter..Loy_DispMstr (CallType, SUBFormat,Disposition, SubDisposition) values (@CallType, @Format,@Disposition, @SubDisposition)", con);
    cmd.Parameters.Add("@CallType", ddlCalltype.Text);
    cmd.Parameters.Add("@Format", ddlFormat.Text);
    cmd.Parameters.Add("@Disposition", TextBox1.Text);
    cmd.Parameters.Add("@SubDisposition", TextBox2.Text);

    con.Open();
    int i = cmd.ExecuteNonQuery();//error on this
    con.Close();
}
