Notwendigkeit, durch statisch erstellte Radiobuttonlist für Werte zu gehen

Question

Ich habe etwas Asp.net-Code mit der folgenden Tabelle geerbt. Ich muss durchgehen und Radiobuttons suchen, die als 'Schlecht' ausgewählt wurden, und dann den zugehörigen Spaltentext finden. Hier ist der aspx-Code:

<table class="checklistTable" id="checkListTable" cellpadding="0" cellspacing="0" runat="server"> 
    <!-- start of visual checks --> 
    <tr> 
     <td colspan="4" class="sectionTitle"> 
      Visual Checks 
     </td> 
    </tr> 
    <tr> 
     <td class="columnRadioPictures"> 
      <asp:Image ID="Image1" runat="server" AlternateText="Ok" ImageUrl="../../images/checkmark.gif" /> 
      <asp:Image ID="Image2" runat="server" AlternateText="Bad" ImageUrl="../../images/xmark.gif" /> 
      <asp:Image ID="Image6" runat="server" AlternateText="N/A" ImageUrl="../../images/notapplicable.gif" /> 
     </td> 
     <td class="columnText"> 
      &nbsp; 
     </td> 
     <td class="columnRadioPictures">

      <asp:Image ID="Image5" runat="server" AlternateText="N/A" ImageUrl="../../images/notapplicable.gif" /> 
     </td> 
     <td class="columnText">

    </tr>

</table> 

Ich habe den folgenden Code hinter versucht, aber lese nicht den Wert des Radiobutton:

foreach (Control ctrl in checkListTable.Controls) 
{ 
    foreach (Control tblCell in ctrl.Controls) 
    { 
     foreach (Control radioBtn in tblCell.Controls) 
     { 
      strCtrl = radioBtn.GetType().ToString(); 
      if (radioBtn is RadioButtonList) 
      { 
       RadioButtonList rbl = (RadioButtonList)ctrl; 

       for (int i = 0; i < rbl.Items.Count; i++) 
       { 
        if (rbl.Items[i].Value.ToString() == "Bad") 
        { 
         //get the text value of the column text 

        } 
       } 
      } 
     } 
    } 
} 

Vielen Dank im Voraus!

Answer 1

Sie können verwenden, um die Control von Jimmy in Better way to find control in ASP.NET bot die ID und die SelectedValue Eigentum des Radiobuttonlist zu erhalten:

ControlFinder<RadioButtonList> radioButtonLists = new ControlFinder<RadioButtonList>(); 
radioButtonLists.FindChildControlsRecursive(checkListTable); 

foreach (RadioButtonList rbl in radioButtonLists.FoundControls) 
{ 
    string id = rbl.ID; 
    string value = rbl.SelectedValue; 
    ... 
} 

Der Text der benachbarten Zelle (zB MANUFACTURER'S MANUAL) ist jedoch nicht leicht zugänglich ist, und Die Verbindung mit der entsprechenden RadioButtonList ist nicht offensichtlich.
