I'm getting a "System.StackOverflowException was unhandled" exception here:

Code:
Private Sub showDetailsView_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles showDetailsView.DataBound
        showDetailsView.DataBind()
    End Sub
when the showDetailsView (a DetailsView component) is made visible by the detailsButton_Click event sub... Why is this happening, and how can I fix this issue?
