ShowFormulaEditor Command

Purpose

It displays the standard dialog box of the editor to set up a dimension element.

Parameters of Use

Value type	Description
IEaxAnalyzer	The express report, for which an expression must be created. Mandatory parameter.
IEaxDataAreaTransformation	The object that is used to work with a data transformation formula. Mandatory parameter.
IDimInstance	It contains properties and methods of access to dictionary data. It is required to search for a transformation element. Optional parameter.
IDimSelectionSet	Selection used to build table.
Boolean	The checkbox determines whether the filter settings panel is available. Available values: True. Use filtering. False. Do not use filtering. Optional parameter.
IEaxDataArea	Returns parameters of the analytical data area. Optional parameter.

Example

Executing the example requires a form, buttons named BUTTON1 and BUTTON2 on the form, the UiErAnalyzer component named UIERANALYZER1 that is a data source for the TabSheetBox1 component, the UiReport1 component that is a data source for the Tabsheetbox2 component. An express report with the FACTS identifier, which contains the calculated element, is connected to UiErAnalyzer1; a regular report with a dimension with the FACTS identifier, which contains the calculated element, is connected to Uireport1.

Add links to the Express, Pivot, Tab, Ui, Dimension and Report system assemblies.

After clicking the Button1 button a dialog box of expression editor for express report calculated element opens, which contains the element formula that can be edited:

After clicking the Button2 button a dialog box of expression editor for regular report calculated element opens, which contains the element formula that can be edited:
