Bind Datatable zu einem Repeater

Question

Ich versuche, eine Datentabelle zu einem Repeater auf aspx zu binden. Ich bekomme den unten erwähnten Fehler bei der "DataBind" -Methode. Ich bin es leid, das seit gestern zu reparieren. Dies ist der Code, den ich habe:

ASPX:

<asp:Repeater ID="HistoryList" runat="server"> 
    <HeaderTemplate> 
    <table class="dataTable" style="width:100%;border-collapse: collapse;padding:0px 0px 0px 0px;"> 
     <tr> 
     <td class="dataHeaderCell">#</td> 
     <td class="dataHeaderCell">Date</td> 
     <td class="dataHeaderCell">Dealer</td> 
     <td class="dataHeaderCell">Security</td> 
     <td class="dataHeaderCell">Bid</td> 
    </tr> 
    </HeaderTemplate> 
    <ItemTemplate> 
     <td class="dataCell right" title='<%# DataBinder.Eval(Container.DataItem, "HistoryId") %>'><%# Container.ItemIndex + 1 %></td> 
     <td class="dataCell"><%# (null != DataBinder.Eval(Container.DataItem, "EffectiveDate")) ? ((DateTime)DataBinder.Eval(Container.DataItem, "EffectiveDate")).ToString("d") : "..."%></td> 
     <td class="dataCell"><%# DataBinder.Eval(Container.DataItem, "OrganizationName") %></td> 
     <td class="dataCell nowrap"><a target="_blank" title="Click Here to View Name..." href='NameView.aspx?page=27&nid=<%# DataBinder.Eval(Container.DataItem, "SecurityId") %>'><%# (60587 == (int)DataBinder.Eval(Container.DataItem, "NameId")) ? DataBinder.Eval(Container.DataItem, "Expr1").ToString() + " (Unknown)" : DataBinder.Eval(Container.DataItem, "Name").ToString() %></a></td> 
     <td class="dataCell nowrap"><%# DataBinder.Eval(Container.DataItem, "Bid") %></td> 
    </ItemTemplate> 
    </table> 
</asp:Repeater> 

CS.aspx:

string dbConnect = System.Configuration.ConfigurationManager.AppSettings["dbConnect"].ToString(); 
    SqlConnection thisConnection = new SqlConnection(@dbConnect); 
    thisConnection.Open(); 

    SqlCommand customCommand = new SqlCommand(queryString.ToString()); 
    customCommand.Connection = thisConnection; 
    customCommand.CommandType = System.Data.CommandType.Text; 

    DataTable dt = new DataTable(); 
    SqlDataAdapter adapter = new SqlDataAdapter(customCommand4); 
    adapter.Fill(dt); 

    DataTable newsDataTable = new DataTable(); 

    foreach(DataRow dr in dt.Rows) 
    { 
    //check for something 
    if (true) 
    { 
     newsDataTable.ImportRow(dr); 
    } 
    } 

    if (0 < newsDataTable.Rows.Count) 
    { 
    HistoryList.DataSource = newsDataTable; 
    HistoryList.DataBind(); 
    HistoryList.Visible = true; 
    HistoryTitle.Text = string.Format(HistoryTitle.Text, HistoryColor.Count); 
    } 

Der Fehler, den ich mit zu kämpfen habe, ist:

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'HistoryId'. ---> at System.Web.UI.DataBinder.GetPropertyValue(Object container, String propName) 
     at System.Web.UI.DataBinder.Eval(Object container, String[] expressionParts)

Kann jemand bitte darauf hinweisen, was ich vermisse oder falsch mache? Vielen Dank.

Answer 1

Modified DataTable newsDataTable = new DataTable(); zu DataTable newsDataTable = dt.Clone(); und statt newsDataTable.ImportRow(dr); verwendet newsDataTable.Rows.Add(dr.ItemArray);
