The direction in which to collapse the Bookmark. Can be either of the following WdCollapseDirection constants: wdCollapseEnd or wdCollapseStart. The default value is wdCollapseStart.

Examples

The following code example adds a Bookmark control with text, and then displays the start and end position of the bookmark before and after collapsing the bookmark.

This example is for a document-level customization.

Private Sub BookmarkCollapse()

    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Dim Bookmark1 As Microsoft.Office.Tools.Word.Bookmark = _
        Me.Controls.AddBookmark(Me.Paragraphs(1).Range, "Bookmark1")

    Bookmark1.Text = "This is sample bookmark text."
    MessageBox.Show("Start and end of Bookmark1 before calling Collapse: " _
        & Bookmark1.Start.ToString() & " and " & Bookmark1.End.ToString)

    Dim Direction As Object = Word.WdCollapseDirection.wdCollapseEnd
    Bookmark1.Collapse(Direction)

    MessageBox.Show("Start and end of Bookmark1 after calling Collapse: " _
        & Bookmark1.Start.ToString() & " and " & Bookmark1.End.ToString)

End Sub

private void BookmarkCollapse()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    Microsoft.Office.Tools.Word.Bookmark bookmark1 =
        this.Controls.AddBookmark(this.Paragraphs[1].Range,
        "bookmark1");

    bookmark1.Text = "This is sample bookmark text.";
    MessageBox.Show("Start and end of bookmark1 before calling Collapse: " +
        bookmark1.Start.ToString() + " and " + bookmark1.End.ToString());

    object Direction = Word.WdCollapseDirection.wdCollapseEnd;
    bookmark1.Collapse(ref Direction);

    MessageBox.Show("Start and end of bookmark1 after calling Collapse: " +
        bookmark1.Start.ToString() + " and " + bookmark1.End.ToString());
}
