Add a Watermark

Some columns benefit from a watermark, which displays as grey text in the field.

A watermark can be added in two ways: A static text watermark can be added to a column, or a view can be registered that displays the watermark depending on certain conditions.

For example, for list boxes that search for particularly named values/objects a watermark can display the expected formats to ensure that the user understands what’s expected. Also, suggested text formats can be useful. If the user is expected to use a namespace convention, indicating it during the add/edit is more useful than providing a warning after the save.

A watermark can be added to these controls:

  • HTML Area
  • Text Box
  • DateTime
  • Combo Box
  • Numeric
  • List Box
  • Text Area

To add a static text watermark to a column:

  1. Access the Page Columns page's Vertical View.

  2. Click Edit.

    View the field descriptions for the Page Columns page

  1. Enter the text in the Watermark Text field.
  2. Click Save.

To use a view to display a watermark:

  1. Write a view with a Dwv suffix and alias the column as boawatermark
  2. Access the Page Columns page's Vertical View.

  3. Click Edit.

    View the field descriptions for the Page Columns page

  2. Select the view in the Watermark View list box.

  3. Enter the binding field name(s) in the Watermark Binding Field Names text box.

    NOTE: Include a comma between names.
