使用多个组合框的值过滤datagridview

Question

我想知道如何使用组合框中的选定值过滤datagridview。我有多个表的数据库。

这是用于填充datagridview并将值添加到组合框中的代码：

            /*OleDbCommand command1 = new OleDbCommand(query1, connection);
            command1.CommandText = query1;*/

            OleDbDataAdapter da1 = new OleDbDataAdapter(query_datagrid, connection);
            DataSet ds = new DataSet();
            //DataTable dat1= new DataTable();
            da1.Fill(ds);
            dataGridView1.DataSource = ds.Tables[0];
            dataGridView1.ReadOnly = true;



            //
            string query1 = "SELECT * FROM House";
            OleDbCommand command1 = new OleDbCommand(query1, connection);
            OleDbDataReader reader1 = command1.ExecuteReader();
            while (reader1.Read())
            {  
                cmbhouse.Items.Add(reader1["House_names"].ToString());

            }
            cmbhouse.ValueMember = "House.ID_house";
            reader1.Close();

            string query2 = "SELECT * FROM House";
            OleDbCommand command2 = new OleDbCommand(query2, connection);
            OleDbDataReader reader2 = command2.ExecuteReader();
            while (reader2.Read())
            {
                cmbfloorhouse.Items.Add(reader2["Floors"].ToString());
                cmbfloorhouse.ValueMember = "ID_house";

            }
            cmbfloorhouse.ValueMember = "House.ID_house";
            reader2.Close();

            string query3 = "SELECT TypeofHouse FROM HouseType";
            OleDbCommand command3 = new OleDbCommand(query3, connection);
            OleDbDataReader reader3 = command3.ExecuteReader();
            while (reader3.Read())
            { 
                cmbtypeofhouse.Items.Add(reader3[0].ToString());
            }
            cmbtypeofhouse.ValueMember = "HouseType.ID_type";
            reader3.Close();
