Hiding a nested grid once again

Question

Once again, I''m trying to hide a table. The problem now is that I have two related tables, one of it has records and the other one don''t. So the second one is shown empty. I would like to be able to hide the empty tables, plus the functionality I have now of not showing the +/- button when all tables are empty. Here''s the code I''m using, in a GGC:


if (e.TableCellIdentity.TableCellType == GridTableCellType.RecordPlusMinusCell)
{
    Element cell = e.TableCellIdentity.DisplayElement;
    Record r = cell.ParentRecord as Record;
    bool makeStatic = true;
    if (r != null && r.NestedTables.Count > 0)
    {
        foreach (NestedTable nt in r.NestedTables)
        {
            if (nt.ChildTable.GetFilteredRecordCount() != 0)
                makeStatic = false;
        }
    }
    if (makeStatic)
    {
        e.Style.CellType = "Static";
        e.Style.Borders.Bottom = new GridBorder(grid.TableModel.Options.DefaultGridBorderStyle, SystemColors.GrayText);
    }
}

At the bottom of this thread, there is a sample that shows how to set the rowheight to zero to hide a child table. Maybe that will work for you in this case.

I just want to hide the related table, not the entire row, because a row can have an empty table and a non-empty table, so just one must be shown.

Hi Serras,

Try this and let me know if this serves your purpose.


		private void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
		{
			if (e.TableCellIdentity.TableCellType == GridTableCellType.RecordPlusMinusCell) 
			{ 
				Record r = e.TableCellIdentity.DisplayElement.ParentRecord as Record; 
				if (r != null && r.NestedTables.Count > 0 && r.NestedTables[0].ChildTable.Records.Count == 0) 
				{ 
					e.Style.Enabled = false; 
					e.Style.Clickable = false;
				} 
			} 
		}

Best regards,
Stanley

That is not the type of hiding I need. I''ve posted a small picture of my grid to explain a bit better what I want to achieve.post.zip

Here is a sample. http://www.syncfusion.com/Support/user/uploads/GGC_PasteSort_af331e6d.zip

The first parent record in the has two empty child tables, so no +/- is shown.

The second parent record has one populated child table and one empty child table. The empty child table is hidden by setting rowheights = 0  for its caption row, column header row and addnew row.
