如何使用動態綁定在AspxGridView中執行頁腳摘要和組摘要？

我做了一個代碼來顯示使用AspxGridView的記錄。現在我想顯示Footer和Grouping的總和（Column_Name），count（Column_Name）。如何使用動態綁定在AspxGridView中執行頁腳摘要和組摘要？

這是我的代碼：

<dx:ASPxGridView ID="ASPxGridView1" runat="server" > 
        <SettingsPager PageSize="50"> 
        </SettingsPager> 
        <Settings ShowFilterRow="True" ShowGroupPanel="True" ShowFooter="True" ShowGroupFooter="VisibleIfExpanded" /> 
        <SettingsCommandButton> 
         <ShowAdaptiveDetailButton ButtonType="Image"></ShowAdaptiveDetailButton> 

         <HideAdaptiveDetailButton ButtonType="Image"></HideAdaptiveDetailButton> 
        </SettingsCommandButton> 
        <SettingsDataSecurity AllowDelete="False" AllowEdit="False" AllowInsert="False" /> 
        <SettingsSearchPanel Visible="True" /> 
       </dx:ASPxGridView>

C＃代碼：

protected void Page_Load(object sender, EventArgs e) 
{ 
if (IsPostBack) 
     { 
      ASPxGridView1.Visible = true; 
      string cs = ConfigurationManager.ConnectionStrings["HQMatajerConnectionString"].ConnectionString; 
      whereQuery = getWhereQuery(); 
      using (SqlConnection con = new SqlConnection(cs)) 
      { 
       string querysss = "select "+txtSelectedColumn.Text+ @" 
          FROM  [HQMatajer].[dbo].[Transaction] as transactions 
          RIGHT JOIN [HQMatajer].[dbo].[TransactionEntry] as transactionsEntry 
          ON transactions.TransactionNumber=transactionsEntry.TransactionNumber 
          INNER JOIN [HQMatajer].[dbo].[Item] as items 
          ON transactionsEntry.ItemID=items.ID 
          INNER JOIN [HQMatajer].[dbo].[Supplier] as suppliers 
          ON items.SupplierID=suppliers.ID 
          LEFT JOIN [HQMatajer].[dbo].[Department] as departments 
          ON departments.ID=items.DepartmentID 
          LEFT JOIN [HQMatajer].[dbo].[Category] as categories 
          ON categories.ID=items.CategoryID 
          where " + txtQuery.Text; 

       SqlCommand cmd = new SqlCommand(); 

       cmd.Connection = con; 
       cmd.CommandText = querysss; 
       con.Open(); 

       SqlDataAdapter sda = new SqlDataAdapter(cmd); 

       sda.Fill(ds); 

       ASPxGridView1.AutoGenerateColumns = true; 
       ASPxGridView1.DataSource = ds; 
       ASPxGridView1.DataBind(); 
      } 
     }

你可以注意到，我的SQL查詢語句。在那個用戶只決定他們想要顯示哪一列。如果他們在select語句中選擇Price column_name。它必須在頁腳中顯示總和（價格）以用於所有記錄和分組以及如果用戶進行分組

也許開始使用LINQ to Entities？和實體框架。 –

您可以在c＃代碼中添加彙總項並在每次回發中更改字段名稱。例如對於頁腳彙總

ASPxSummaryItem gs = new ASPxSummaryItem(); 
gs.FieldName = txtSelectedColumn.Text; 
gs.SummaryType = DevExpress.Data.SummaryItemType.Sum; 
this.ASPxGridView1.TotalSummary.Add(gs);

如果字段名稱不會改變，你可以刪除舊摘要，每次在需要的列中添加一個新的。你也可以爲每個小組總結做同樣的事情。你也可以檢查出這些https://documentation.devexpress.com/#AspNet/DevExpressWebASPxGridView_GroupSummarytopic和https://documentation.devexpress.com/#AspNet/DevExpressWebASPxGridView_TotalSummarytopic
