Add bookmarks to a report when you want to provide a customized table of contents or to provide customized internal navigation in the report. Typically, you add bookmarks to locations in the report to which you want to direct users. You can create your own strings to use as bookmarks, or, for groups, you can set the bookmark to the group expression. After you create bookmarks, you can add report items that the user can click to go to each bookmark. These items are typically text boxes or images.
In Design view , select a report item to which you want to add a bookmark. The properties for the selected item appear in the Properties pane.
In the BookmarkId property, type a string that is the label for this bookmark. Alternatively, click the ellipsis to open the Expression dialog box to specify an expression that evaluates to a label.
The BookmarkId can be any string, but it must be unique in the report. If the BookmarkID is not unique, an action to the bookmark finds the first matching bookmark.
