+Summary: Datagrid command postback doesn't behave like on MS.NET
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+When I have a command on a datagrid clicking on the button doesn't seem to
+post back to the command handler.
+
+To reproduce it just copy this code into an aspx file and click on the TEST
+link, you should see the price printed on the top of the page. It seems to
+work fine on windows using mono but I have only tested it once on windows.
