OpenMatrixDataSource(DataSource: IMatrixDataSource);
DataSource. Abstract multidimensional data source, which data should be loaded to express report.
The OpenMatrixDataSource property loads data to the express report from a non-cube source.
For example, data of modeling variables obtained as a result of a modeling problem calculation can be used as a non-cube source. Access to data variables is executed by means of the VariableStub property.
Executing the example requires a form with a button named Button1, the UiErAnalyzer component named UiErAnalyzer1 and other components displaying data of the express report loaded to UiErAnalyzer1. The repository contains a modeling container with the KONT_MODEL identifier. This container contains a modeling problem with the Problem_1 identifier configured to calculate models.
Sub Button1OnClick(Sender:Object; Args: IMouseEventArgs);
Var
MB: IMetabase;
CrInfo: IMetabaseObjectCreateInfo;
Expr: IEaxAnalyzer;
Problem: IMsProblem;
Setting: IMsProblemCalculationSettings;
Calc: IMsProblemCalculation;
MDS: IMatrixDataSource;
Begin
// Temporary express report
MB := MetabaseClass.Active;
CrInfo := MB.CreateCreateInfo;
CrInfo.ClassID := MetabaseObjectClass.KE_CLASS_EXPRESSREPORT;
Expr := MB.CreateObject(CrInfo).Edit As IEaxAnalyzer;
// Calculated modeling problem
Problem := MB.ItemByIdNamespace("PROBLEM", MB.ItemById("KONT_MODEL").Key).Bind As IMsProblem;
Setting := Problem.CreateCalculationSettings;
// Calculate modeling problem
Calc := Problem.Calculate(Setting);
// Data by the first output variable
MDS := Calc.VariableStub(Problem.VariableStubs(MsVariableKind.Output).Item(0));
// Load to express report
Expr.OpenMatrixDataSource(MDS);
// Load express report to UiErAnalyzer1
UiErAnalyzer1.ErAnalyzer := Expr;
UiErAnalyzer1.Active := True;
End Sub Button1OnClick;
After executing the example the PROBLEM modeling problem is calculated. Report on the first output variable is loaded to the UiErAnalyzer1 component. Data is displayed in all components using UiErAnalyzer1 as a data source.
