UltraWebGrid doesn't restore its state after postback

Hi, I don’t know why after post back UltraWebGrid doesn’t restore data from viewstate.
Grid appeares empty.

  1. I bind data like that:
protected void reportDisplayDD_SelectedIndexChanged(object sender, EventArgs e)
{
    BusinessFacade busFacade = new BusinessFacade();
    UltraWebGridSurveys.DataSource = busFacade.GetSurveyListForReportWriter(Convert.ToInt32(reportDisplayDD.SelectedValue));
    UltraWebGridSurveys.DataBind();
}

Please, have a look at attached pictures.

Here markup of UltraWebGrid.
