    • loading the report from a file or stream;
    • loading the report from the designer's undo buffer;
    • assigning another object to this object using the Assign(Base) or AssignAll methods;

    GetContextMenu()

    Gets the object's context menu.

    Declaration
    public override ContextMenuBase GetContextMenu()
    Returns
    Type Description
    ContextMenuBase

    Null reference if object does not have a menu.

    Overrides
    FastReport.ComponentBase.GetContextMenu()
    Remarks

    Do not call this method directly. You may override it if you are developing a new component for FastReport.

    GetPageDesignerType()

    Gets a page designer for this page type.

    Declaration
    public override Type GetPageDesignerType()
    Returns

    Type Description
    SelectionPoint[]

    Array of SelectionPoint objects.

    Overrides
    FastReport.ComponentBase.GetSelectionPoints()
    Remarks

    Selection point is a small square displayed at the object's sides when object is selected in the designer. You can drag this square by the mouse to change the object's size. For example, the TextObject has eight selection points to change its width and height by the mouse.

    If you are developing a new component for FastReport, you may override this method if your object has non-standard set of selection points. For example, if an object has something like "AutoSize" property, it would be good to disable all selection points if that property is true, to disable resizing of the object by the mouse.
