Blank Row showing in Hierarchy Table

[David Kucharski]

I have a radgrid on my page. It has a Details Table for children. For the parent rows that have no children I do now want any row(s) to show. I have used the below code and when I do, I still see a blank row underneath my parent row. What am I doing wrong?

The attached file is how my grid looks.

//If the details have no records, make it invisible
      protected void rgCirculationDetails_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridNoRecordsItem && e.Item.OwnerTableView != rgCirculationDetails.MasterTableView)
                e.Item.OwnerTableView.Visible = false;
        }

//below code puts an empty string for a parent row that has no children
        protected void rgCirculationDetails_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)
        {
            try
            {
                GridDataItem parentItem = e.DetailTableView.ParentItem as GridDataItem;

                int parentRow = Convert.ToInt32(parentItem.GetDataKeyValue("ParentRow"));
                string geography = parentItem.GetDataKeyValue("Geography").ToString().Trim();

                if (e.DetailTableView.DataMember == "GeographyRows")
                {
                    if (parentRow == 1)
                    {
                        circulationServiceObj.CircDetail = circulationObj.GetCircDetailsForParentRow(circSetID, geography, dayID).CircDetail;
                        e.DetailTableView.DataSource = circulationServiceObj.CircDetail.CircDetail;
                    }
                    else
                    {
                        e.DetailTableView.DataSource = String.Empty;
                    }
                }
            }
            catch (SoapException ex)
            {
            }
        }

Hello David,

Thank you for contacting us.

The reason for that behavior is that you are hiding the DetailTableView but you need to hide the GridNestedViewItem. A possible solution is to call parent until you get the GridNestedViewItem or use the hardcode approach.

if (e.Item is GridNoRecordsItem && e.Item.OwnerTableView != RadGrid1.MasterTableView)
{
    e.Item.OwnerTableView.Parent.Parent.Visible = false;
}

Please give it a try and let me know about the result.
