Gets a command to check all items in the control.
public ICommand CheckAllCommand { get; }Gets or sets the mode of the check boxes in the control. For more information see the TreeViewCheckBoxMode type.
public TreeViewCheckBoxMode CheckBoxMode { get; set; }Gets a command to check a specific item in the control. The command accepts a parameter specifying the path to the item. The path is a collection if unique identifiers of items. The first element of the path identifies an item at the root level. The second element of the path identifies a child of the root item etc. The IdentityMemberPath property can be used to specify the unique identifier at each level of the hierarchy.
public ICommand CheckCommand { get; }Gets or sets the collection of items, which are currently checked in the control.
public IList CheckedItems { get; set; }Gets a command to collapse all items in the control.
public ICommand CollapseAllCommand { get; }Gets a command to collapse a specific item in the control. The command accepts a parameter specifying the path to the item. The path is a collection if unique identifiers of items. The first element of the path identifies an item at the root level. The second element of the path identifies a child of the root item etc. The IdentityMemberPath property can be used to specify the unique identifier at each level of the hierarchy.
public ICommand CollapseCommand { get; }Gets or sets a collection of TreeViewDescriptors describing the hierarchical data.
public IList<TreeViewDescriptor> Descriptors { get; set; }Gets a command to expand all items in the control.
public ICommand ExpandAllCommand { get; }Gets a command to expand a specific item in the control. The command accepts a parameter specifying the path to the item. The path is a collection if unique identifiers of items. The first element of the path identifies an item at the root level. The second element of the path identifies a child of the root item etc. The IdentityMemberPath property can be used to specify the unique identifier at each level of the hierarchy.
public ICommand ExpandCommand { get; }Gets or sets a value indicating whether load on demand is enabled.
public bool IsLoadChildrenOnDemandEnabled { get; set; }Gets or sets a command to execute when an item is checked after a user interaction. The command should accept a single parameter with the checked item.
public ICommand ItemCheckedCommand { get; set; }Gets or sets a command to execute when an item is collapsed after a user interaction. The command should accept a single parameter with the collapsed item.
public ICommand ItemCollapsedCommand { get; set; }Gets or sets a command to execute when an item is expanded after a user interaction. The command should accept a single parameter with the expanded item.
public ICommand ItemExpandedCommand { get; set; }Gets or sets a command to execute when an item is unchecked after a user interaction. The command should accept a single parameter with the unchecked item.
public ICommand ItemUncheckedCommand { get; set; }Gets or sets the indentation in pixels between a parent item and its child items.
public double LevelIndentation { get; set; }Gets or sets a command to execute when loading an item on demand. The command should accept a single parameter of type TreeViewLoadChildrenOnDemandCommandContext.
public ICommand LoadChildrenOnDemandCommand { get; set; }Gets or sets the current scroll orientation of the control. Form ore information see the TreeViewScrollOrientation type.
public TreeViewScrollOrientation ScrollOrientation { get; set; }Gets a command to uncheck all items in the control.
public ICommand UncheckAllCommand { get; }Gets a command to uncheck a specific item in the control. The command accepts a parameter specifying the path to the item. The path is a collection if unique identifiers of items. The first element of the path identifies an item at the root level. The second element of the path identifies a child of the root item etc. The IdentityMemberPath property can be used to specify the unique identifier at each level of the hierarchy.
public ICommand UncheckCommand { get; }Methods
Checks the item in hierarchy with the specified path.
public bool Check(IEnumerable itemPath)Specifies the path to an item in the hierarchy to checked. The path is a collection if unique identifiers of items. The first element of the path identifies an item at the root level.
