Controls

Adding a control reference opens a dialog box containing a list of the columns, computed fields, report controls, and text controls in the document.

Control references can also be added to empty attribute values or element contents using drag-and-drop from the Control List view. Column references can also be added using drag-and-drop from the Column Specifications view.

Drag-and-drop cannot replace You cannot drag-and-drop an item on top of another item to replace it. For example, if you want to replace one control reference with another control reference, or with an DataWindow expression, you first need to delete the control reference you want to replace.
