# SUBPAGE

The SUBPAGE control defines an area in which an HTML page is shown. The URL of the page is not statically defined, but is dynamically controlled by the application.

Due to the browser's capability to embed installed plug-ins, you can use non-HTML objects to be called - and which the browser is able to understand. For example, if you have Microsoft Office installed (or the viewers for Microsoft Office documents) and you pass the name of a Word document as the URL, the Word document will be embedded into the page.

The following topics are covered below:

- Properties

## Properties

Basic
valueprop | Name of the adapter parameter that provides the URL to be displayed inside the SUBPAGE control. Please note: the SUBPAGE control only re-renders its inner content if the URL provided by the property really changes. The SUBPAGE control does not "know" if something changed inside the contained page and that it has to redraw the page. - If you want to refresh the inner page explicitly append some random number to your URL, e.g.: http://...url...?RANDOM=45435. By changing the number the browser will reload the URL. | Obligatory |
width | Width of the control. There are three possibilities to define the width: (A) You do not define a width at all. In this case the width of the control will either be a default width or - in case of container controls - it will follow the width that is occupied by its content. (B) Pixel sizing: just input a number value (e.g. "100"). (C) Percentage sizing: input a percantage value (e.g. "50%"). Pay attention: percentage sizing will only bring up correct results if the parent element of the control properly defines a width this control can reference. If you specify this control to have a width of 50% then the parent element (e.g. an ITR-row) may itself define a width of "100%". If the parent element does not specify a width then the rendering result may not represent what you expect. | Sometimes obligatory | 100 120 140 160 180 200 50% 100%
height | Height of the control. There are three possibilities to define the height: (A) You do not define a height at all. As consequence the control will be rendered with its default height. If the control is a container control (containing) other controls then the height of the control will follow the height of its content. (B) Pixel sizing: just input a number value (e.g. "20"). (C) Percentage sizing: input a percentage value (e.g. "50%"). Pay attention: percentage sizing will only bring up correct results if the parent element of the control properly defines a height this control can reference. If you specify this control to have a height of 50% then the parent element (e.g. an ITR-row) may itself define a height of "100%". If the parent element does not specify a width then the rendering result may not represent what you expect. | Sometimes obligatory | 100 150 200 250 300 250 400 50% 100%
comment | Comment without any effect on rendering and behaviour. The comment is shown in the layout editor's tree view. | Optional |
Appearance
width | (already explained above) |  |
height | (already explained above) |  |
scrolling | Definition of the scrollbar's appearance. You can define that the scrollbars only are shown if the content is exceeding the control's area ("auto"). Or scrollbars can be shown always ("scroll"). Or scrollbars are never shown - and the content is cut ("hidden"). Default is "auto". | Optional | auto yes no
pagestyle | CSS style definition that is directly passed into this control. With the style you can individually influence the rendering of the control. You can specify any style sheet expressions. Examples are: border: 1px solid #FF0000 background-color: #808080 You can combine expressions by appending and separating them with a semicolon. Sometimes it is useful to have a look into the generated HTML code in order to know where direct style definitions are applied. Press right mouse-button in your browser and select the "View source" or "View frame's source" function. | Optional |
colspan | Column spanning of control. If you use TR table rows then you may sometimes want to control the number of columns your control occupies. By default it is "1" - but you may want to define the control to span over more than one columns. The property only makes sense in table rows that are snychronized within one container (i.e. TR, STR table rows). It does not make sense in ITR rows, because these rows are explicitly not synched. | Optional | 1 2 3 4 5 50 int-value
rowspan | Row spanning of control. If you use TR table rows then you may sometimes want to control the number of rows your control occupies. By default it is "1" - but you may want to define the control to span over more than one columns. The property only makes sense in table rows that are snychronized within one container (i.e. TR, STR table rows). It does not make sense in ITR rows, because these rows are explicitly not synched. | Optional | 1 2 3 4 5 50 int-value
alwaysreload | When setting to false, the subpage is not reloaded when a page switch is executed, default is true. | Optional | true false
Binding
valueprop | (already explained above) |  |
Natural
njx:natname | If a Natural variable with a name not valid for Application Designer (for instance #FIELD1) shall be bound to the control, a different name (for instance HFIELD1) can be bound instead. If the original name (in this case #FIELD1) is then specified in this attribute, the original name is generated into the parameter data area of the Natural adapter and a mapping between the two names is generated into the PROCESS PAGE statement of the Natural adapter. This mapping must not break a once defined group structure. If for instance a grid control that is bound to a name of GRID1 contains fields that are bound to FIELD1 and FIELD2 respectively, the corresponding njx:natname values may be #GRID1.#FIELD1 and #GRID1.#FIELD2, but not #GRID1.#FIELD1 and #MYGRID1.#FIELD2. | Optional |
njx:natcomment | The value of this attribute is generated as comment line into the parameter data area of the Natural adapter, before the field name. The Map Converter, for instance, uses this attributes to indicate for a generated statusprop variable to which field the statusprop belongs. | Optional |
