Fore.NET Syntax

Add(Value: Prognoz.Platform.Interop.ExtCtrls.MetaAttributeParamItem);

Parameters

Value. Parameter to be added to the collection.

Description

The Add method adds the specified parameter to the collection.

Fore Example

Executing the example requires a form with the Button1 button and the MetaAttributesBreadcrumb component named MetaAttributesBreadcrumb1. The MetaAttributesBreadcrumb1 component is linked to a time series database.

    Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
    Var
        Setting: IMetaAttributeSetting;
        AttrParam: IMetaAttributeParamItem;
    Begin
        Setting := MetaAttributesBreadcrumb1.MetaAttributeSettings.FindById("DL");
        //Set up parameter
        AttrParam := New MetaAttributeParamItem.Create;
        AttrParam.Id := "Param1";
        AttrParam.Key := 1;
        AttrParam.Name := "Period 1";
        AttrParam.Tag := "Day;Week";
        AttrParam.Visible := True;
        //Add parameter to collection
        Setting.MetaParamItemsCollection.Add(AttrParam);
        //Set up parameter
        AttrParam := New MetaAttributeParamItem.Create;
        AttrParam.Id := "Param2";
        AttrParam.Key := 2;
        AttrParam.Name := "Period 2";
        AttrParam.Tag := "Month;Year";
        AttrParam.Visible := True;
        //Add parameter to collection
        Setting.MetaParamItemsCollection.Add(AttrParam);
        //Set the first parameter as attribute value
        Setting.SelectedParam := Setting.MetaParamItemsCollection.FindById("Param1");
    End Sub Button1OnClick;

Clicking the button creates two parameters for the Period attribute. The first parameter is set as attribute value.

Fore.NET Example

Executing the example requires a .NET form with the Button1 button and the MetaAttributesBreadcrumbNet component named MetaAttributesBreadcrumbNet1. The MetaAttributesBreadcrumbNet1 component is linked to a time series database.

    Private Sub button1_Click(sender: System.Object; e: System.EventArgs);
    Var
        Setting: IMetaAttributeSetting;
        AttrParam: MetaAttributeParamItem;
    Begin
        Setting := MetaAttributesBreadcrumbNet1.CtrlBox.MetaAttributeSettings.FindById("DL");
        //Set parameter
        AttrParam := New MetaAttributeParamItemClass();
        AttrParam.Id := "Param1";
        AttrParam.Key := 1;
        AttrParam.Name := "Period 1";
        AttrParam.Tag := "Day;Week";
        AttrParam.Visible := True;
        //Add parameter to collection
        Setting.MetaParamItemsCollection.Add(AttrParam);
        //Set up parameter
        AttrParam := New MetaAttributeParamItemClass();
        AttrParam.Id := "Param2";
        AttrParam.Key := 2;
        AttrParam.Name := "Period 2";
        AttrParam.Tag := "Month;Year";
        AttrParam.Visible := True;
        //Add parameter to collection
        Setting.MetaParamItemsCollection.Add(AttrParam);
        //Set the first parameter as attribute value
        Setting.SelectedParam := Setting.MetaParamItemsCollection.FindById("Param1");
    End Sub;

Clicking the button creates two parameters for the Period attribute. The first parameter is set as attribute value.
