Set ReportParam in Epicor Customization

In Epicor, I needed to customize the Sales Order Pick List report screen so it defaults to a wider From and To Ship By date range. In customization, this means updating the ReportParam value when the form loads:


private void SOPickListForm_Load(object sender, EventArgs args)
{
// wrong approach, change data source of control
// EpiTokenDate tdtFrom = (EpiTokenDate) csm.GetNativeControlReference("1f043839-c70e-41e0-8d1b-c33fd3d7e3c5");

// change from date
EpiDataView epiDataView = (EpiDataView) oTrans.EpiDataViews["ReportParam"];
epiDataView.dataView[epiDataView.Row]["FromDate"] = DateTime.Now.AddMonths(-6);
}


Normally, to access the text field for a control in a customization you use csm.GetNativeControlReference. But, in this case, I needed to change the ReportParam, which is accessed through oTrans.EpiDataViews["ReportParam"] dataset.
