Why is my control not populated with XML data?

[mark4asp]

I have created two DropDownList controls on my form which I want to
populate with data from an XML file (stored in the xml subdirectory)

Here is the code I use.

It does not work. I shows "System.Data.DataRowView" in both the value
and text fields of the DropDownLists

In debug, I noticed that:
ds.Tables["date"].Rows.Count = 20
dds.Tables["date"].DefaultView.Count = 20

There are 20 items in the xml file.

Furthermore, when I add a watch for "ds.Tables["date"].DefaultView", I
can click on "Data View Visuliser" (in debug again) and it shows the
table information (20 rows, 2 columns each).

What else do I need to do to load this xml data into my controls?

1) code:

DataSet ds = new DataSet();
ds.ReadXml(@"..\xml\dates.xml");

ddlFromDate.DataSource = ds.Tables["date"].DefaultView;
ddlFromDate.DataBind();
ddlToDate.DataSource = ds.Tables["date"].DefaultView;
ddlToDate.DataBind();

2) xml file: dates.xml
