I have a gridview in a page that uses an objectdatasource. The gridview has sorting enabled. The gridview is inside an updatepanel that has a trigger attached to a timer. The gridview will not rerun the datasource on timer expiration. i know the timer works because I have a label that changes the time everytime the timer expires.

If you resort the gridview it will update.

Any idea's?

I have spent ages with the same problem.

in the page load function rebind the control.

GridView1.DataBind();

this seams to work.
