Wow - what horrible code.

Try this:

if (DataList1.Controls.Length > 0)
{
Control c = DataList1.Controls[0];
Label l = c.FindControl("PriceLabel") as Label;
if (l != null)
{
string Price = l.Text;

Apart from the layers of code with no error checking, what on earth possesses you to do a double.Parse, then turn it back to a string ? If you want to make sure the value is a double, use double.TryParse, not a method that, if it fails, throws an exception.
