For example, a "tight" print in A4 format will be perfectly legible in A3 format.

The management of control anchoring includes two parameters:

• The anchor of control: this parameter is used to define the modification that will be applied to the control according to the change of report size. The control can be moved to the left, its size can be increased in width.
• The anchor rate: this parameter is used to manage the percentage by which the control is moved or stretched. This parameter allows you to:
  • keep a control centered in width in the report regardless of its size,
  • proportionally enlarge some report controls.

• Several WLanguage properties allow you to find out the anchoring characteristics defined in the editor. These properties cannot be used to modify the anchors defined in the editor.
• The anchoring is available for the controls only (it is not available for the blocks).

Anchoring a control in a report

1. Select one or more controls to anchor.
2. Define the anchoring of controls:
   • in the "UI" tab of the description window of control ("Description" from the popup menu of control),
   • via "Anchor" from the popup menu of the control.
     
     Remark: If the print mode of the report is not suited for the anchors, the print mode can be changed from this window directly.
3. In this window, choose the type of anchoring that will be used. The most common options are represented by icons:
   

   	No anchor	The control is not modified when the report is resized. No anchoring option is selected.
   	Width	The control stretches to the right when the report is enlarged. To change the speed at which a control stretches in relation to the report, use the anchor rate in width.
   	Right	The controls moves to the right when the report is enlarged. To make the control move slower or faster, use the anchor rate to right.
   	Centered in width	The control remains centered in width in the report regardless of the report width.
   	Versions 20 and later Height New in version 20 Height Height	The control stretches to the bottom when the report height is enlarged. To change the speed at which a control stretches in relation to the report, use the anchor rate in height.
   	Versions 20 and later Width and Height New in version 20 Width and Height Width and Height	The control stretches to the right and to the bottom when the report is enlarged. To change the speed at which a control stretches in relation to the report, use the anchor rate in height and the anchor rate in width.
   	Versions 20 and later Height and Right New in version 20 Height and Right Height and Right	The control stretches to the bottom and moves to the right when the report is enlarged. To make the control move slower or faster, use the anchor rate to right. To change the speed at which a control stretches in relation to the report, use the anchor rate in height.
   	Versions 20 and later Bottom New in version 20 Bottom Bottom	The control moves to the bottom when the report is enlarged toward the bottom. To make the control move slower or faster, use the anchor rate to bottom.
   	Versions 20 and later Width and Bottom New in version 20 Width and Bottom Width and Bottom	The control stretches to the right and moves to the bottom when the report is enlarged. To make the control move slower or faster, use the anchor rate to bottom. To change the speed at which a control stretches in relation to the report, use the anchor rate in width.
   	Versions 20 and later Right and Bottom New in version 20 Right and Bottom Right and Bottom	The control moves to the right and to the bottom when the report is enlarged. To make the control move slower or faster, use the anchor rate to bottom and the anchor rate to right.
   	Versions 20 and later Horizontally centered at bottom New in version 20 Horizontally centered at bottom Horizontally centered at bottom	The control remains centered in width in the report regardless of the report width. However, the control is anchored to the right and it moves to the right when the report is enlarged. To make the control move slower or faster, use the anchor rate to bottom.
   	Versions 20 and later Centered in height New in version 20 Centered in height Centered in height	The control remains centered in height inside the report regardless of the report height.
   	Versions 20 and later Vertically centered to right New in version 20 Vertically centered to right Vertically centered to right	The control remains centered in height inside the report regardless of the report height. However, the control is anchored to the right and it moves to the right when the report is enlarged. To make the control move slower or faster, use the anchor rate to right.
   	Versions 20 and later Centered New in version 20 Centered Centered	The control remains centered in height and in width inside the report regardless of the report size.

4. Define (if necessary) the different anchor rates.
5. Validate.

• Auto-resizing controls are displayed in the report editor with a specific sign: a line with a down arrow.
  
• At runtime, an auto-resizing control will automatically stretch vertically if it is too small to display all its content.

Print mode of a report and anchoring

• Print the report as it is: In this case, the content exceeding the report size will not be printed.
• Automatically stretch or reduce to the supported format: The report is automatically stretched or reduced to adapt to the paper format.
• Stretch or reduce by applying the anchors: The report is adapted to the selected format by using the defined anchors.

These print modes can be selected or modified in the "Options" tab of the description window of the report.

Option found in the "Print" pane of the ribbon

• the default paper format of the report proposed in portrait mode and in landscape mode.
• the paper formats supported by the default printer of the computer.
