Connection still open? Try using 'using': http://www.w3enterprises.com/articles/using.aspx

As far as I am aware you cannot bind a source field to more than one control at a time, therefore as you are binding all fields to the grid view you cant then bind them to another source. Check by removing the line that binds to the gridview.

You also need to set the datepicker DataSource as well.
