将ListView绑定到动态手风琴

Question

在page_load中，我使用来自SpGetCompanies的数据动态创建了标头，该数据工作正常。然后，我试图在每个动态创建的手风琴窗格中添加一个ListView，数据源为SpSearchPublicationsTop1。

protected void Page_Load(object sender, EventArgs e) 
    {  
     if (!this.IsPostBack) 
     { 
      SQLConnection dataAccessor = new SQLConnection(); 
      dtCompanies = dataAccessor.SpGetCompanies(); 

      if (dtCompanies.Rows.Count > 0) 
      { 
       AccordionPane pn; 

       Label lblContent; 
       int j = 0; 
       for (int i = 0; i < dtCompanies.Rows.Count; i++) 
       { 
        lblHeader = new Label(); 
        lblHeader.Text = dtCompanies.Rows[i][1].ToString(); 

        lblContent = new Label();      
        lblContent.Text = "Hallo"; 

        pn = new AccordionPane(); 
        pn.ID = "Pane" + j; 
        pn.HeaderContainer.Controls.Add(lblHeader); 

        ListView view = new ListView(); 

        view.LayoutTemplate = new LayoutTemplate(); 
        view.ItemTemplate = new ItemTemplate(); 
        //view = (ListView)FindControl("lv_result"); 

        view.DataSource = SQLConnection.SpSearchPublicationsTop1(lblHeader.Text); 
        view.DataBind(); 

        #region commented stuff 
        //dt2 = SQLConnection.SpSearchPublicationsTop1(lblHeader.Text); 

        //if (dt2.Rows.Count > 0) 
        //{ 
        // //view = (ListView)FindControl("lv_result"); 

        // //column1.Text = dt2.Rows[0][0].ToString();      
        // //view.Columns.Add(column1); 
        // //Label lblAcronym = new Label(); 
        // //lblAcronym.Text = dt2.Rows[0][0].ToString(); 

        // //view.DataSource = lblAcronym; 
        // view.DataSource = dt2; 
        // view.DataBind(); 

        //} 

        //listView1.Columns.Add(column1); 

        //foreach (DataRow dr in dt2.Rows) 
        //{ 
        // ListViewItem lvi = new ListViewItem(dr[0].ToString()); //1.st column in datatable, instead of 0 you can write column`s name like: ["CustomerID"] 
        // lvi.SubItems.Add(dr[1].ToString()); //2nd column from datatable 
        // view.Items.Add(lvi); 
        //} 

        //this.Controls.Add(view); 

        //ListView lv_result = new ListView(); 
        ////lv_result.ItemTemplate = new ItemTemplate(); 
        //lv_result.ID = "lvpane" + i; 
        //lv_result.Visible = true; 

        //dt2 = SQLConnection.SpSearchPublicationsTop1(lblHeader.Text); 

        //if (dt2.Rows.Count > 0) 
        //{ 
        // lv_result.DataSource = dt2; 
        // lv_result.DataBind(); 
        //} 

        //var level2 = (ListView)FindControl("lv_result"); 
        //level2.ItemTemplate = view.ItemTemplate; 

        ////level2.DataSource = dt2(e.AccordionItem.DataItemIndex); 
        ////level2.DataBind(); 

        //dt2 = SQLConnection.SpSearchPublicationsTop1(lblHeader.Text); 

        //if (dt2.Rows.Count > 0) 
        //{ 
        // level2.DataSource = dt2; 
        // level2.DataBind(); 
        //} 
        #endregion 


        pn.ContentContainer.Controls.Add(view); 
        //pn.ContentContainer.Controls.Add(lblContent); 
        Accordion1.Panes.Add(pn); 
        ++j; 
       } 
      } 
     } 

    } 

private class LayoutTemplate : ITemplate 
    { 

     public void InstantiateIn(Control container) 
     { 
      var ol = new HtmlGenericControl("ol"); 
      var li = new HtmlGenericControl("li") { ID = "itemPlaceholder" }; 
      ol.Controls.Add(li); 

      container.Controls.Add(ol); 
     } 
    } 

    private class ItemTemplate : ITemplate 
    { 
     public void InstantiateIn(Control container) 
     { 
      var li = new HtmlGenericControl("li"); 

      li.DataBinding += DataBinding; 
      container.Controls.Add(li); 
     } 

     public void DataBinding(object sender, EventArgs e) 
     { 
      var container = (HtmlGenericControl)sender; 
      var dataItem = ((ListViewDataItem)container.NamingContainer).DataItem; 

      container.Controls.Add(new Literal() { Text = dataItem.ToString() }); 
     } 
    } 

与手风琴头上面的代码都做工精细，但不是在内容的ListView数据，我只得到：System.Data.DataRowView

我在做什么错？

你缺少一个电话：

DataBinder.Eval(container.DataItem, "YouBindingProperty"); 

例子：

public void DataBinding(object sender, EventArgs e) 
{ 
    var genericControl = (HtmlGenericControl)sender; 
    var container = (ListViewDataItem)container.NamingContainer; 

    container.Controls.Add(new Literal() { Text = DataBinder.Eval(container.DataItem, "YouBindingProperty") }); 
}
