Drag and Drop

You use the drag-and-drop feature to create an expression when the data in the source is transferred to the target field exactly as it is, and no transformation is required.

Select the appropriate class in the source and in the target; then click the property in the source and drag the cursor to the property in the target. When you drag this property to the Expression cell in the target pane and release the mouse button, the class and property information populates the Expression column in the Target pane in the following form: <class>.<property>.
