IEaxDataSources.AddDescriptor

Fore Syntax

AddDescriptor (Desc: IMetabaseObjectDescriptor) : IEaxDataSource;

Fore.NET Syntax

AddDescriptor (Desc: Prognoz.Platform.Interop.Metabase.IMetabaseObjectDescriptor) : Prognoz.Platform.Interop.Express.IEaxDataSource;

Description

The AddDescriptor method adds a data source to express report.

Fore Example

Executing the example requires the button named Button1, the express report with the EXPRESS_REPORT identifier and the cube with the CUBE_1 identifier on the form. Add links to the Express and Metabase system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    MB: IMetabase;
    Expr: IEaxAnalyzer;
    ExprDS: IEaxDataSources;
    Cube: IMetabaseObjectDescriptor;
Begin
    MB := MetabaseClass.Active;
    Expr := MB.ItemById("EXPRESS_REPORT").Edit As IEaxAnalyzer;
    ExprDS := Expr.DataSources;
    Cube := MB.ItemById("CUBE_1");
    ExprDs.AddDescriptor(Cube);
    (Expr As IMetabaseObject).Save;
End Sub Button1OnClick;

After executing the example clicking the button adds the CUBE_1 data source for the EXPRESS_REPORT express report.

Fore.NET Example

The requirements and result of the Fore.NET Example execution match with those in the Fore Example. Instead of the Fore components use their Fore.NET analogs.
Imports Prognoz.Platform.Interop.Metabase;
Imports Prognoz.Platform.Interop.Express;

Private Sub button1_Click(sender: System.Object; e: System.EventArgs);
    Var
    MB: IMetabase;
    Expr: IEaxAnalyzer;
    ExprDS: IEaxDataSources;
    Cube: IMetabaseObjectDescriptor;
Begin
    MB := Self.Metabase;
    Expr := MB.ItemById["EXPRESS_REPORT"].Edit() As IEaxAnalyzer;
    ExprDS := Expr.DataSources;
    Cube := MB.ItemById["CUBE_1"];
    ExprDs.AddDescriptor(Cube);
    (Expr As IMetabaseObject).Save();
End Sub;
