Solution 1

you can set the checked states as below

C#

cblMinistries.Items.Add(SqlDataPull,true);

or if you need to set it conditionally

C#

while (dr.Read())
{
    SqlDataPull = dr[0].ToString();
    bool checkedstatus = (put your condition here...); 
    cblMinistries.Items.Add(SqlDataPull,checkedstatus);
}

C#

private void PopuMinistry()
{
    using (SqlConnection conn = new SqlConnection())
    {
        conn.ConnectionString = ConfigurationManager
                .ConnectionStrings["constr"].ConnectionString;
        using (SqlCommand cmd = new SqlCommand())
        {
            cmd.CommandText = "select Homecellname from tblministries order by Homecellname";
            cmd.Connection = conn;
            conn.Open();
            using (SqlDataReader sdr = cmd.ExecuteReader())
            {
                while (sdr.Read())
                {
                    ListItem item = new ListItem();
                    item.Text = sdr["Homecellname"].ToString();
                    item.Value = sdr["Homecellname"].ToString();
                    item.Selected = true;
                    chkHobbies.Items.Add(item);
                }
            }
           conn.Close();
        }
    }
