BlockBase SAP SE The main element that holds the content that is displayed in an {@link sap.uxap.ObjectPageLayout ObjectPageLayout}, but not necessarily only there. <h3>Overview</h3> The blocks give the flexibility to combine different content types. A block is a control that: <ul> <li>Has modes and a view associated to each mode. At rendering time, the view associated to the mode is rendered.</li> <li>Can use all view types for storing its internal control tree (XML, JS, JSON, HTML)</li> </ul> As any UI5 view, the XML view can have a controller which automatically comes with a <code>this.oParentBlock</code> attribute (so that the controller can interact with the block). The <code>oParentBlock</code> is firstly available in <code>onParentBlockModeChange</code> method. If the controller implements the <code>onParentBlockModeChange</code> method, this method will be called with the <code>sMode</code> parameter when the view is used or reused by the block. 1.26 sap.ui.core/Control Determines the mode of the block. See {@link sap.uxap.ObjectPageSubSectionMode ObjectPageSubSectionMode}. When <code>BlockBase</code> is used inside an <code>ObjectPageLayout</code>, the <code>mode</code> property is inherited from the respective {@link sap.uxap.ObjectPageSubSection SubSection}. The <code>mode</code> property of <code>BlockBase</code> changes when the <code>mode</code> property of <code>ObjectPageSubSection</code> changes. Determines the visibility of the block. Determines on how many columns the layout will be rendered. Allowed values are integers from 1 to 4 and "auto". Determines if the block should automatically adjust its inner forms. Allowed values are "BlockColumns" and "OneColumn" and "None". If the value is "BlockColumns", then the inner form will have as many columns as the colspan of its parent block. If the value is "OneColumn", the inner form will have exactly one column, regardless the colspan of its parent block. If the value is "None", no automatic adjustment of inner forms will be made and the form will keep its original column count. Determines whether the show more button should be shown. <b>Note:</b> The property will take effect if the <code>BlockBase</code> is inside <code>ObjectPageSubSection</code> and would be ignored in case the <code>BlockBase</code> is nested inside another <code>BlockBase</code>. Fired when an aggregated view is instantiated. The initialized view. Map external UI5 model and internal Block model Internal aggregation that contains all views inside this Block The current view. Corresponds to the currently specified <code>mode</code> of the <code>sap.uxap.BlockBase<code>. Can be used as a getter for the internally created view. <b>Note:</b> As the views are created asynchronously, this association will be updated only after the view creation is completed. Applications that want to be notified when a view is created should subscribe to the <code>viewInit</code> event.
