IE11  
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Grid1.SelectedRowIndex < 0 Then
            Alert.Show("请选择！")
            Exit Sub
        End If
        Session.Add("id", Grid1.Rows(Grid1.SelectedRowIndex).Values(1))
        Session.Add("mc", Grid1.Rows(Grid1.SelectedRowIndex).Values(3))
        PageContext.RegisterStartupScript(ActiveWindow.GetHidePostBackReference())   '运行到这就报图上的错误
    End Sub

    Protected Sub Grid1_RowDoubleClick(ByVal sender As Object, ByVal e As FineUI.GridRowClickEventArgs) Handles Grid1.RowDoubleClick
        If Grid1.SelectedRowIndex < 0 Then
            Alert.Show("请选择！")
            Exit Sub
        End If

        Session.Add("id", Grid1.Rows(Grid1.SelectedRowIndex).Values(1))
        Session.Add("mc", Grid1.Rows(Grid1.SelectedRowIndex).Values(3))

        PageContext.RegisterStartupScript(ActiveWindow.GetHidePostBackReference())
    End Sub


在按钮是  PageContext.RegisterStartupScript(ActiveWindow.GetHidePostBackReference())  报错但是在表格双击是不报错
