2つのdataTable（C＃とDevExpress）を持つマスターディテールグリッド

Question

プログラムで2つのdataTableをマスターディテールグリッドにコード化しようとしました。残念なことに1週間は、私は解決策をGoogleにしようとすると私はまだ失敗します。 私はC＃とDevExpressを使用して、GridView2としてLevel1を追加設定しています。 メインはgridview1であり、すべてがgridContorl1の下にあります。以下は私がやったコードですが、私の実験プログラムの最後のステップを進めていくことを願っています。 メインテーブルはtableSalesOrder &です。詳細テールはtableDetailです。与えられたマスター行で詳細行を検索するには

private void btnLoadSO_Click(object sender, EventArgs e) 
    { 
     LoadOutstandingSO(); 
     LoadDetailDS(); 
     gridControl1.DataSource = tableSalesOrder; 
    } 

    private void LoadOutstandingSO() 
    { 
     if (tableSalesOrder == null) 
      tableSalesOrder = new DataTable("dtSO"); 
     else 
      tableSalesOrder.Clear(); 

     string sqlSelect2a = "select 0 AS [Check], k.ItemCode, k.[Data Count], l2.Description, l2.ItemGroup, l2.ItemType,"

Answer 1

関係にtableSalesOrderとtableDetailが、時に選択tableSalesOrder ItemCode、tableDetailのみマスター・ディテール・ビュー・グリッドの下ItemCodeが表示されますどのように、あなたはrelationshipを追加する必要がありますデータセット内のこれらのテーブルの間。この関係は、詳細行がそのマスター行に関連付けられる列を定義します。

詳細レベル名が関係名と一致する場合、XtraGridは関係から詳細ビューのデータを自動的に検索できます。 level designerまたはprogrammaticallyを使用してレベル名を割り当てることができます。

さらに、XtraGridは、データセットにリレーションシップがあり、ShowOnlyPredefinedDetailsオプションが偽に設定されている場合、詳細レベルを自動的に設定できます。
