Get value from dynamically generated textboxes to XML

I added 89 textboxes dynamically. I want to get the value of the textboxes to xml. I can add the textboxes just fine the problem is I cant get the values on those dynamically added textboxes.

For example i want to get value from textBox1 to the node "F1" in XML ,from textBox2 to node "F2" in XML.

private void button1_Click(object sender, EventArgs e)
{  
    XmlNodeList xnList;
    XmlDocument doc = new XmlDocument();
    string dosyayolu = Application.StartupPath + "\\coupling.xml";
    doc.Load(dosyayolu);

    if (globaller.hangimenu == "TWT1")
    {
        xnList = doc.SelectNodes("/coup/TWT1");
    }
    else
    {
        xnList = doc.SelectNodes("/coup/TWT2");
    }

    for (int i = 0; i < 89; i++)
    {
        foreach (XmlNode xn in xnList)
        {
            xn["F" + (i + 1).ToString()].InnerText = "k";
            // xn["F1"].InnerText = textBox1.Text;
        }
    }

    doc.Save(dosyayolu);
}

you can do it like this:

//create
StackPanel sp = new StackPanel();
for(int i=0;i<89;i++)
{
    TextBox tb = new TextBox();
    sp.Children.Add(tb);
}

//get
foreach(TextBox tb in sp.Children)
{

}

or you can add all the textboxs to a list,and get them from list by index

i'm guessing your textboxes are of name textBox1, textBox2, .... also your xml nodes start on F1 instead of F2 so i altered the For loop a bit 

for (int i = 1; i < 90; i++)
  {
      foreach (XmlNode xn in xnList)
      {
          // this if textboxes on form, yourUserControlName if it is under a usercontrol
          var tb = (TextBox)this.Controls["textBox" + i];
          xn["F" + i].InnerText = tb.Text;

      }
  }

You could use the extension ChildrenOfType<T>(). Assuming that grid is the parent of all your TextBoxes..

var textBoxes= grid.ChildrenOfType<TextBox>().ToArray();
for (int i = 0; i < 89; i++)
{
    foreach (XmlNode xn in xnList)
    {
        xn["F" + (i + 1).ToString()].InnerText = "k";
        xn["F1"].InnerText = textBoxes[ i ].Text;
    }
}
