    PlaceHolder Class
    In This Topic
    Using the PlaceHolder object you can forward records of properties to the references objects. You also can get information about place holders in macros.

    Remarks
    To reduce the number of displayed properties refer to two user settings. First is 'USER.MacrosGui.XMDlgPlaceholder.ShowOnlyFilled' which controls if properties with empty value in 'Variable' column are displayed. Second setting is 'USER.MacrosGui.XMDlgPlaceholder.ShowCurrentValueFilled' which controls if properties with empty value in 'Current value' column are displayed.
    Example
    The following example shows how to use class PlaceHolder. Here is example of PlaceHolder having IsChangeable property set.
    // Create PlaceHolder
    PlaceHolder placeHolder = new PlaceHolder();
    placeHolder.Create(oPage);
    placeHolder.Location = new PointD(80.0, 200.0);
    placeHolder.Name = "PlaceHolder 1";
    
    // Add variables and set values to records
    placeHolder.Variables.Add("X VAR");
    placeHolder.ValueSets.Add("Set 1");
    placeHolder.ValueSets.Add("Set 2");                
    
    //setting values
    MultiLangString oMultiLangString = new MultiLangString();
    oMultiLangString.AddString(ISOCode.Language.L___, "test string");
    placeHolder.Values["X VAR", "Set 1"] = oMultiLangString;
    
    // Set variable for FUNC_TEXT property
    Eplan.EplApi.Base.MultiLangString funcText = new MultiLangString();
    funcText.AddString(ISOCode.Language.L_en_US, "<X VAR>");
    placeHolder.SetPropertyEntry(oFunction, Properties.Function.FUNCTION_MESSAGETEXT, funcText);
    
    //Apply record
    placeHolder.ApplyRecord("Set 1");
    
    
    
    //creating PlaceHolder
    PlaceHolder oPlaceHolder = new PlaceHolder();
    oPlaceHolder.Create(m_oTestPage);
    
    oPlaceHolder.Variables.Add(new PlaceHolder.Variable(oPlaceHolder, "test variable 1"));
    oPlaceHolder.Variables.Add("test variable 2");
    oPlaceHolder.Variables.Add("test variable 3");
    oPlaceHolder.Variables.Remove("test variable 2");
    
    //adding value sets
    oPlaceHolder.ValueSets.Add("value set 1");
    oPlaceHolder.ValueSets.Add("value set 2");
    oPlaceHolder.ValueSets.Add("value set 3");
    oPlaceHolder.ValueSets.Remove("value set 1");                
    
    //setting values
    MultiLangString oMultiLangString = new MultiLangString();
    oMultiLangString.AddString(ISOCode.Language.L___, "test string");
    oPlaceHolder.Values["test variable 1", "value set 3"] = oMultiLangString;
    
    //setting IsChangeable
    oPlaceHolder.Variables["test variable 3"].IsChangeable = !oPlaceHolder.Variables[0].IsChangeable;
    oPlaceHolder.Variables.Add("test variable 2", true);                
    
    //clearing variables and value sets                 
    oPlaceHolder.ValueSets.Clear();
    oPlaceHolder.Variables.Clear();

    Public Properties
     NameDescription
    Public PropertyActivates the properties of the page for the place holder object.  
    Public PropertyGets/Sets a list of StorableObject references to a PlaceHolder object. The originally assigned references are replaced.  
    Public PropertyReturns an array of objects cross-referenced with this object (i.e. having the same name - in case of functions - or otherwise associated) (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyReturns the project as number. The number is unique for all open projects in one session. The number changes when the project is closed and opened again. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertySets display sequence. The drawing order flag will be used to sort elements according to drawing order within a group. If elements chare the same value the drawing order will result from order of the data model. Default value is 67. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public PropertyReturns a group that the Placement object belongs to. If the Placement object doesn't belong to any group, NULL is returned. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public Property

    Determines if the the StorableObject is locked.

    The StorableObject is locked when it was explicitly or implicitly locked.

    (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyReturns true if the placement is placed (Inherited from Eplan.EplApi.DataModel.Placement)
    Public PropertyDetermines if StorableObject is read-only (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyGets/Sets visibility of the object as set in its properties dialog. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public Property

    Determines if the the StorableObject is transient.

    The StorableObject is transient when it was created by default constructor and:

    it is a Eplan.EplApi.DataModel.Page and it was not assigned a Eplan.EplApi.DataModel.Project,

    it is a Eplan.EplApi.DataModel.Placement or any class derived from it and was not assigned a Eplan.EplApi.DataModel.Page.

    (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyDetermines if StorableObject is correct database object and is not deleted. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyGets/Sets the actual visibility state of the object. (Inherited from Eplan.EplApi.DataModel.Graphics.GraphicalPlacement)

    Public PropertyOverridden. Get or set the placement's location.  
    Public PropertyGets/Sets the name of the placeholder.  
    Public PropertyGets/Sets the name of a record, specified by its index.  
    Public PropertyCount of records.  
    Public PropertyCount of objects referenced by the PlaceHolder.  
    Public PropertyCount of Variables.  
    Public PropertyReturns the object identifier as number. The number is unique for all objects of this type. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public PropertyReturns the page the Placement is on, or assigns a Page object to the placement. If the placement was previously assigned to another page, it is removed from old one and assigned to the page given as an argument. (Inherited from Eplan.EplApi.DataModel.Placement)
    Public PropertyReturns the project the StorableObject belongs to. (Inherited from Eplan.EplApi.DataModel.StorableObject)
    Public Property.NET Property enabling access to P8 properties of the PlaceHolder object.
