使用從xml文件生成的按鈕來設置單選按鈕值

Question

案例：我的Windows窗體應用程序正在從XML文件創建按鈕和單選按鈕。對於每個創建的按鈕（預設爲XML），我想將選中的單選按鈕（XML中的Lijst）更改爲我的XML中描述的值。

我的想法：應該有一個點擊方法，它會讀取預設點擊的xml值並將單選按鈕更改爲正確的值。但我沒有線索如何做到這一點。

代碼的XML：

<Lijsten> 

    <Lijst> 
    <Titel>Discipline</Titel> 
    <Waardes>Elektro</Waardes> 
    <Waardes>Mechanisch</Waardes> 
    <Waardes>Civiel</Waardes> 
    <Waardes>Proces</Waardes> 
    <Waardes>N.v.t.</Waardes> 
    </Lijst> 
    <Lijst> 
    <Titel>Soort</Titel> 
    <Waardes>Tekening</Waardes> 
    <Waardes>Tekst doc</Waardes> 
    <Waardes>Afbeelding</Waardes> 
    <Waardes>N.v.t.</Waardes> 
    </Lijst> 

    <Preset> 
    <ButtonTitel>Preset 1</ButtonTitel> 
    <sets> 
     <RadioButtonTitel>Discipline</RadioButtonTitel> 
     <RadioButtonValue>Elektro</RadioButtonValue> 
    </sets> 
    <sets> 
     <RadioButtonTitel>Soort</RadioButtonTitel> 
     <RadioButtonValue>Afbeelding</RadioButtonValue> 
    </sets> 
    </Preset> 
    <Preset> 
    <ButtonTitel>Preset 2</ButtonTitel> 
    <sets> 
     <RadioButtonTitel>Discipline</RadioButtonTitel> 
     <RadioButtonValue>Mechanisch</RadioButtonValue> 
    </sets> 
    <sets> 
     <RadioButtonTitel>Soort</RadioButtonTitel> 
     <RadioButtonValue>Tekening</RadioButtonValue> 
    </sets> 
    </Preset> 

</Lijsten> 

代碼創建單選按鈕的：

foreach (XmlNode node in nodes) 
{ 
    radioButtonCounter += 1; 
    count += 1; 
    if (count < 4) 
    { 
     int heightRadioButtons = 0; 
     WidthPanelsRow1 += 155; 
     Panel panel = new Panel(); 
     panel.Size = new Size(140, 200); 
     panel.Location = new Point(WidthPanelsRow1, heightPanelsRow1); 
     panel.Name = "panel" + count.ToString(); 
     panel.BackColor = Color.LightGray; 

     Label lbl = new Label(); 
     lbl.Text = node["Titel"].InnerText; 
     lbl.Location = new Point(0, 0); 
     lbl.Font = font1; 
     panel.Controls.Add(lbl); 

     int counterLastRadioButton = 0; 
     XmlNodeList waardeNodes = node.SelectNodes("Waardes"); 
     foreach (XmlNode wNode in waardeNodes) 
     { 
       counterLastRadioButton += 1; 
       heightRadioButtons += 20; 
       RadioButton rb = new RadioButton(); 
       rb.Text = wNode.InnerText; 
       rb.Location = new Point(5, heightRadioButtons); 
       rb.Name = node["Titel"].InnerText; 
       if (waardeNodes.Count - 1 < counterLastRadioButton) 
       { 
        rb.Checked = true; 
       } 
       panel.Controls.Add(rb); 
     } 
     this.Controls.Add(panel); 
    }else... 
} 

代碼用於創建預設按鈕：

foreach (XmlNode node in nodes) 
{ 
    count += 1; 
    if (count < 4) 
    { 
      WidthPanelsRow1 += 155; 
      Panel panel = new Panel(); 
      panel.Size = new Size(140, 40); 
      panel.Location = new Point(WidthPanelsRow1, heightPanelsRow1); 
      panel.Name = "panel" + count.ToString(); 

      XmlNodeList titelPreset = node.SelectNodes("ButtonTitel"); 
      foreach (XmlNode titelNode in titelPreset) 
      { 
       Button btn = new Button(); 
       btn.Text = titelNode.InnerText; 
       btn.Location = new Point(0, 0); 
       btn.Name = node["ButtonTitel"].InnerText; 
       btn.Size = new Size(140,40); 
       btn.Click += (sender, args) => 
       { 
        //What to do here? 
       }; 
       panel.Controls.Add(btn); 
      } 
      this.Controls.Add(panel); 
     }else... 
} 

感謝。

嘗試使用詞典。見下面的代碼：
