How can I get the text from a texbox that is dynamically made?

//Assessment type combobox
comboBoxAssessments.Add(new ComboBox());
System.Drawing.Point pCombo = new System.Drawing.Point(450, 25 + i * 75);
(comboBoxAssessments[i] as ComboBox).Location = pCombo;
(comboBoxAssessments[i] as ComboBox).Size = new System.Drawing.Size(100, 20);
(comboBoxAssessments[i] as ComboBox).Items.AddRange(new object[]{
     "Coursework",
     "Exam"
});

I'm working on a grade prediction tool for a university degree that has to have dynamically built controls. The code above dynamically builds a combobox to let the user choose from "Coursework" or "Exam" assessment types. "comboBoxAssessments" is an arrayList that holds any given number of comboBoxes. Once I have the user's selection, I'm saving it into an XML file using the XMLTextWriter class. How can I go about getting the user's selection from the combobox during runtime and then write it to an XML file? I've tried using:

textWriter.WriteStartElement("Assessment Type", "");                        //Assessment type start
textWriter.WriteString((comboBoxAssessments[i] as ComboBox).SelectedItem.ToString);
textWriter.WriteEndElement();                                               //Assessment type end

but found no glory. If anyone has some ideas, please throw them my way and I'll try them out.

It's just comboBoxAssessments.Text. Use this for your second line:

textWriter.WriterString(comboBoxAssessments[i].Text);

The Text property is already a string, and will be the value of the user's selection.
