#### Parameters

The Report Viewer for ActiveX provides several optional parameters to customize the look of the viewer and to control its functionality. Apply values to these parameters by using the standard PARAM tag in your HTML code.

##### DisplayGroupTree

Indicates whether the Group Tree is displayed when the viewer first appears. If the Has Group Tree parameter is set to false, this parameter is ignored. If the Group Tree is hidden, the user can display it by clicking the Toggle Group Tree button in the viewer.

- A value of 1 (TRUE) displays the Group Tree.
- A value of 0 (FALSE) hides the Group Tree.

##### EnableAnimationControl

Indicates whether the viewer displays the Animation Control. The Animation Control runs while a report is being generated and downloaded. Once the report completely arrives at the client web browser, the animation stops.

- A value of 1 (TRUE) displays the Animation Control.
- A value of 0 (FALSE) prevents the Animation Control from being displayed.

##### EnableDrillDown

Indicates whether a user can drill-down on summary values in a drill-down report. In a drill-down report that appears in the Report Viewer for ActiveX, the mouse pointer becomes a magnifying glass over any group or value that can be drilled down on. Double-click the group or value to display a separate Drill-Down tab inside the viewer.

- A value of 1 (TRUE) indicates the user can drill-down on reports.
- A value of 0 (FALSE) indicates the user is not allowed to drill-down on reports.

##### EnableExportButton

Indicates whether or not the Export button appears in the Report Viewer. If the Export button appears, the user can export the displayed report to Microsoft Word, Microsoft Excel, HTML 3.2, or Seagate Crystal Reports format.

- A value of 1 (TRUE) displays the Export button.
- A value of 0 (FALSE) prevents the Export button from being displayed.

##### EnableGroupTree

Indicates whether the viewer generates a Group Tree for the report. Does not indicate whether or not the Group Tree is displayed. If HasGroupTree is set to 0, ShowGroupTree is automatically set to 0.

- A value of 1 (TRUE) generates a Group Tree.
- A value of 0 (FALSE) prevents a Group Tree from being generated.

##### EnablePrintButton

Indicates whether the user can print the report to a printer. When the user clicks the Print button, the report is sent to a printer according to the settings selected by the Standard Print dialog box. If the Has Print Button is set to 0, then you cannot print. For more information, see Printing from Report Viewers.

- A value of 1 (TRUE) displays the Print button.
- A value of 0 (FALSE) prevents the Print button from being displayed.

##### EnableRefreshButton

Indicates whether a Refresh button is available in the viewer to allow the user to refresh report data.

- A value of 1 (TRUE) allows users to refresh report data.
- A value of 0 (FALSE) prevents users from refreshing report data.

##### EnableSearchControl

The Search control and button that appear in the Report Viewer for ActiveX allow a user to easily search for and jump to instances of a specific value or field that appear in the report. The user enters the value of interest in the drop-down list, then clicks the Search button to find the first instance of that value. Clicking the button again finds successive instances of the value in the report.

- A value of 1 (TRUE) displays the Search controls.
- A value of 0 (FALSE) prevents the Search controls from being displayed.

##### EnableZoomControl

Use the Zoom Control to switch between levels of magnification in the Report Viewer for ActiveX. With the Zoom Control, you can magnify the report up to 400% of its original size, or reduce it down to 25% in order to see more of the report at once.

- A value of 1 (TRUE) displays the Zoom Control.
- A value of 0 (FALSE) prevents the Zoom Control from being displayed.
