Table break detect end of page Flowdocument

hello,

I am a beginner using flowdocument. I am trying to print but before printing I would like to check if what i'm printing will fit on the page and if not should be put to the next page and not be cut.

I know I can use this code below but i want to detect that what i'm printing will not fit

Section section = new Section();
section.BreakPageBefore = true;

 var tfc2 = from b in conn.tblReQResults
                       where b.ResultID == GlobalVariables.ResultID
                       orderby b.tblTestPram.tblSubTest.tblPanel.tblCategory.Category
                       group b by new { b.tblTestPram.tblSubTest.tblPanel.tblCategory.CatID, b.tblTestPram.tblSubTest.tblPanel.tblCategory.Category } into ynb
                       select new { CatID = ynb.Key.CatID, Category = ynb.Key.Category };
            foreach (var ynb in tfc2)
            {             
                    table1.RowGroups[0].Rows.Add(new TableRow());
                    currentRow = table1.RowGroups[0].Rows[j + 1];
                    currentRow.Cells.Add(new TableCell(new Paragraph(new Run("\n" + ynb.Category))));
                    currentRow.Cells[0].TextAlignment = TextAlignment.Center;
                    currentRow.Cells[0].FontSize = 12;
                    currentRow.Cells[0].FontWeight = System.Windows.FontWeights.Bold;
                    currentRow.Cells[0].BorderThickness = new Thickness(0, 0, 0, 0.5);
                    currentRow.Cells[0].BorderBrush = System.Windows.Media.Brushes.LightGray;
                    currentRow.Cells[0].ColumnSpan = 9;

j++;

}

Thank you in advance
