    got such a problem.
    Have an updatepanel with autopostback combo.
    Selection in the combo is affecting grid datasource.
    If the combo item is a first one, that says "Select [blabla]" - data in the grid must be cleared.

    When I use DataSource = null assignment, the grid is getting hidden, but when I select some item after this, there is exception
    "Failed to load viewstate".

    So, how to organize the code properly in my case?
