ILaner.EndDateParamId

Syntax

EndDateParamId: String;

Description

The EndDateParamId property determines identifier of the parameter that sets the end date of displaying data in the workbook.

Comments

The parameter defined in the EndDateParamId property must be of the Date And Time type to work correctly (DbDataType.DateTime) or Date (DbDataType.Date). To determine parameter type, use the IMetabaseObjectParam.DataType property.

If the EndDateParamId value is not set, the date of workbook data display end is determined with the ILaner.EndDate property.

If the EndDateParamId and ILaner.EndDate properties are set, the date of workbook data display end is determined with the last set property.

The date of data display end must be greater than that of data display start. To set the parameter determining the date of workbook data display start, use the ILaner.StartDateParamId property.

The EndDateParamId property affects only the data display in the workbook. To determine the calculation options of a specific series, use the ILanerTransformPeriod interface.

Example

Executing the example requires a form with the LanerBox component and the UiErAnalyzer component with the UiErAnalyzer1 identifier, that is a data source for LanerBox. Repository must contain a workbook with the WBK identifier.

Add links to the Dal and Metabase system assemblies.

Sub SetWbkParam;
Var
    mb: Imetabase;
    Wbk: IMetabaseObject;
    WbkParams: IMetabaseObjectParams;
    Param: IMetabaseObjectParam;
    Eax: IEaxAnalyzer;
    Laner: ILaner;
    ObjI: ImetabaseObjectInstance;
Begin
    mb := MetabaseClass.Active;
    // Get workbook
    Wbk := mb.ItemById("WBK").Edit;
    // Get workbook parameters
    WbkParams := Wbk.Params;
    // Clear collection of parameters
    WbkParams.Clear;
    // Add parameter
    // determining the date of data display start
    Param := WbkParams.Add;
    Param.DataType := DbDataType.Date;
    Param.DefaultValue := "01.01.2002";
    Param.Id := "START_DATE";
    Param.Name := "Start date";
    // Add parameter
    // determining the date of data display end
    Param := WbkParams.Add;
    Param.DataType := DbDataType.Date;
    Param.Id := "END_DATE";
    Param.Name := "End date";
    Param.DefaultValue := "31.12.2010";
    // Save changes
    Wbk.Save;
    // Get object to set up workbook
    Wbk.Bind;
    Eax := Wbk As IEaxAnalyzer;
    Laner := Eax.Laner;
    // Set start and end dates of data display with parameters
    Laner.StartDateParamId := "START_DATE";
    Laner.EndDateParamId := "END_DATE";
    // Open the workbook with parameter values by default
    ObjI := Wbk.Open(Eax.OwnParamValues);
    UiErAnalyzer1.Active := False;
    UiErAnalyzer1.Instance := ObjI;
    UiErAnalyzer1.Active := True;
End Sub SetWbkParam;

After executing the example the WBK workbook contains parameters determining start and end dates of data display. The workbook is opened to view in LanerBox by the values of parameters set by default.
