Cleaning up documents might be necessary when building documents dynamically. Various document sections are added, forced page breaks are inserted at different positions and end-users can modify the resulting document. A typical task is to remove all empty pages from a document that consist only of a page break or section break character.
The following method uses the PageEnumerator to loop through all pages. If the Length of a page equals 1, the page is removed.
[C#] private void RemoveEmptyPages() { TXTextControl.PageCollection.PageEnumerator pageEnum = textControl1.GetPages().GetEnumerator(); pageEnum.MoveNext(); int pageCounter = textControl1.GetPages().Count; for (int i = 0; i < pageCounter; i++) { TXTextControl.Page curPage = (TXTextControl.Page)pageEnum.Current; if (curPage.Length == 1) { textControl1.Select(curPage.Start - 1, 1); textControl1.Selection.Text = ""; } else pageEnum.MoveNext(); } }
[Visual Basic] Private Sub RemoveEmptyPages() Dim pageEnum As TXTextControl.PageCollection.PageEnumerator = textControl1.GetPages().GetEnumerator() pageEnum.MoveNext() Dim pageCounter As Integer = textControl1.GetPages().Count For i As Integer = 0 To pageCounter - 1 Dim curPage As TXTextControl.Page = DirectCast(pageEnum.Current, TXTextControl.Page) If curPage.Length = 1 Then textControl1.[Select](curPage.Start - 1, 1) textControl1.Selection.Text = "" Else pageEnum.MoveNext() End If Next End Sub
