I had to pre-populate a FormView that contains a textbox with the current date and time.
Googled and found this link which proved to be quite useful, though not exactly what I wanted.
Pre-populate DetailsView InsertItemTemplate TextBox with User.Identity.Name value - ASP.NET Forums

Anyway, what you need to do is to first add an event handler for "ondatabound" in the FormView.
Assuming you have a textbox named "TextBoxDataOfEntry" in the InsertItemTemplate of the FormView, this is how I got the current date and time to be populated in the textbox.
protected void FormView1_DataBound(object sender, EventArgs e)
{
if (FormView1.CurrentMode == FormViewMode.Insert)
{
DateTime datetime = DateTime.Today;
TextBox tbDateOfEntry = (TextBox)FormView1.FindControl("TextBoxDateOfEntry");
tbDateOfEntry.Text = datetime.ToString();
}
}//end FormView1_DataBound
