DockingLayout Blazor API

DockingLayout Properties

NameTypeDefaultDescription
AutoLoadStateboolfalseEnable/Disable the automatic state loading. There must be a previously saved state of the Layout in order to load it.
AutoSaveStateboolfalseEnable/Disable the automatic state saving.
Note: In order to save the state of the element it must have an id.
DisabledboolfalseEnables or disables the element.
DraggablebooltrueIf set to false it will disable the dragging of DockingLayout items. If set items can only be repositioned using the API methods.
FloatablebooltrueIf set to false it will disable item floating. This means that if a Window is floated as a result of dragging it will be returned back ot it's original position instead of being floated outside the DockingLayout. Already floated LayoutPanel items will not be affected.
HideSplitterBarsboolfalseHides all splitter bars inside the element.
LayoutobjectN/ADetermines the structure of the element. This property represents an array of objects that define the hierarchy of the items inside the element and their specific settings. Each object must have a type attribute that defines it's behavior.
Three types of objects are allowed:
  • LayoutGroup - Represents a group of items (Splitter). Used when the user wants more than one DockingLayout item in a single container.
    Properties:
    • orientation - A string value indicating the orientation of the Splitter group. Possible values: 'horizontal', 'vertical'.
    • size - A string | number value indicating the size of the Splitter group.
    • items - An array of LayoutPanel object definitions.
    • resizeMode - A string indicating the resize mode. Possible values: 'none', 'adjacent', 'end', 'proportional'.
    • resizeStep - A nummeric value that determines the step of resizing.
    • liveResize - Determines if splitter resizing happens while dragging or not.
  • LayoutPanel - Represents a DockingLayout item (TabsWindow). LayoutPanels can have one or many items (TabItem).
    Properties:
    • id - the ID of the LayoutPanel.
    • autoHide - a boolean property that determines if the LayoutPanel is autoHidden.
    • autoHidePosition - determines the autoHide position of the item if 'autoHide' property is set. Possible values: 'top', 'bottom', 'left', 'right'.
    • dropPosition - Determines the possible positions for the item at which a new item can be dropped as a result of dragging. Possible values: 'top', 'bottom', 'left', 'right', 'center', 'header', 'layout-top', 'layout-bottom', 'layout-left', 'layout-right'. Positions with the 'layout' prefix reflect on LayoutPanelItems that are children of the LayoutPanel.
    • label - the Label of the LayoutPanel window.
    • tabPosition - Determines the position of the Tab labels inside the LayoutPanel.
    • layout - determines the DockingLayout owner of the LayoutPanel. Accepts a string indicating the ID of a DockingLayout on the page or a direct reference to it.
    • headerButtons - an Array of strings that define the buttons in the header section of the DockingLayout item.
    • tabCloseButtons - a boolean property that Enables or disables the close buttons inside each Tab item label inside the DockingLayout item.
    • tabOverflow - same as 'overflow' property of SmartTabs. It defines the overflow mode of the labels of the Tab items inside a DockingLayout item.
    • selectionMode - the same as SmartTabs selection modes. Applies to Tab items inside a DockingLayout item.
    • tabResize - the same as 'resize' property of SmartTabs. Allows resizing the Tab labels inside the DockingLayout item.
    • locked - Locks the size of the item and does not allow resizing.
    • max - sets the maximum size of the item.
    • min - sets the minimum size of the item
    • size - sets the size of the item.
    • items - an array of objects. Each object defines the structure of a LayoutPanelItem.
  • LayoutPanelItem - Represents a LayoutPanel item (TabItem).
    Properties:
    • id - the ID of the Tab item.
    • label - a string representing the label of the Tab item.
    • content - represents the content of the Tab item. Can be anything.
    • selected - determines if the item is selected. By default the first added item to the LayoutPanel is automatically selected.
    • draggable - a boolean property that allows to disable the dragging of the Tab item.

LiveResizeboolfalseWhen enabled the resizing operation happens live. By default this feature is not enabled and the user sees a hightlighted bar while dragging instead of the actual splitter bar.
Localestring"en"Sets or gets the language. Used in conjunction with the property messages.
MessagesobjectN/ASets or gets an object specifying strings used in the widget that can be localized. Used in conjunction with the property locale.
ReadonlyboolfalseIf the element is readonly, users cannot interact with it.
RightToLeftboolfalseSets or gets the value indicating whether the element is aligned to support locales using right-to-left fonts.
ResizeStepint5Determines the resize step during reisizing
SnapModeDockingLayoutSnapModeDockingLayoutSnapMode.AdvancedDetermines the snap mode. Two modes are available:
  • simple - allows dragging of a single tab item inside or outside the layout. A semi-transparent highlighter is used to indicate the possible locations where the dragged item can be dropped. The user has to drop the dragged item inside one of the possible drop zones indicated by the highlighter.
  • advanced - allows dragging of a whole TabsWindow with items or a single tab item. Uses a Visual Studio style feedback that indicates the possible drop locations. The user has to drop the target over one of the icons inside the feedback.

The feedback/highlighter is displayed when the dragging of an item begins.
Themestring""Determines the theme. Theme defines the look of the element
UnfocusableboolfalseIf is set to true, the element cannot be focused.
