Abstract

A system and method of displaying user interface information with respect to navigation of a hierarchical namespace is disclosed. The hierarchical namespace includes a first set of items representing a top level portion of the hierarchical namespace and a second set of items representing lower levels of the hierarchical namespace.

Claims

1. A method of displaying user interface information with respect to navigation of a hierarchical namespace, the hierarchical namespace including a first set of items representing a top level portion of the hierarchical namespace and a second set of items representing lower levels of the hierarchical namespace, the method comprising:

displaying each of the items in the first set of items in a first navigation display area at a display device;

displaying a second navigation display area at the display device, the second navigation display area including a column explore display area;

detecting a selected use of a particular item in the second navigation display area;

creating a direct link to the particular item; and

displaying the direct link to the particular item in a link area of the first navigation display area at the display device, the link area associated with the selected one of the first set of items;

wherein a first link to a most recently used data item in a first column of the column explorer display area is displayed in a first location in the first navigation display area, the first link associated with a first data item in the first navigation display area, and a second link to a second most recently used data item in a second column of the column explorer display area is displayed at a second location in the first navigation display area, the second link associated with a second data item in the first navigation display area.

2. The method of claim 1, further comprising manipulating a user control to access the particular item without requiring further navigation upon selection of the direct link in the first navigation display area.

3. The method of claim 1, wherein the selected use of the particular item is detected when a user selects an end node of the hierarchical namespace and after a delay period expires, when data is presented in a results viewing area and after expiration of a results viewing period of time, when the user takes an action with respect to results data associated with the particular item, or when the user takes an action related to the particular item.

4. The method of claim 1, wherein a location of the particular item of the list of one or more items in the second navigation display area is stored in a computer memory and wherein the particular item is immediately useable upon selection of the direct link, such that the direct link provides a shortcut to access the particular item.

20. The method of claim 1, wherein a new most recently used link is displayed in the link area to replace the direct link previously displayed in the link area.

5. A user interface comprising:

a navigation pane including a plurality of selectable items, the navigation pane displayable in a first region of a display at a display device; and

a column explorer display area selectively displayable in a second region of the display at the display device, the second region distinct from the first region;

wherein a first link to a most recently used data item in a first column of the column explorer display area is displayed in a first location in the navigation pane, the first link associated with a first data item in the navigation pane, and a second link to a second most recently used data item in a second column of the column explorer display area is displayed at a second location in the navigation pane, the second link associated with a second data item in the navigation pane.

6. The user interface of claim 5, wherein the navigation pane includes a first control item to select a first tree data structure display and a second control item to select a second tree data structure display, wherein either the first tree data structure display or the second tree data structure display is visible;

wherein the first tree data structure display presents hierarchical data of a tree data structure with respect to a column display orientation and the second tree data structure display presents the hierarchical data of the tree data structure with respect to a top-down orientation.

7. A system comprising:

navigation pane logic to provide a navigation pane as part of a user interface at a display device, the navigation pane including a plurality of displayable data items representing a first set of high level nodes of a hierarchical data structure;

expandable column explorer logic to selectively present a column explorer display area that includes one or more columns in response to selection of a column explorer activation selector within the navigation pane, the one or more columns to display a second set of data items representing portions of the hierarchical data structure distinct from the first set of high level nodes where the second set of data items of the hierarchical data structure are selectively displayed by the one or more columns, wherein a first of the one or more columns includes a first portion of the second set of data items and a second of the one or more columns includes a second portion of the second set of data items, wherein the first portion identifies data items at a different level of the hierarchical data structure than the second portion; and

logic to display a first link to a most recently used data item in a first column of the column explorer display area in a first location in the navigation pane, the first link associated with a first data item in the navigation pane, and to display a second link to a second most recently used data item in a second column of the column explorer display area at a second location in the navigation pane, the second link associated with a second data item in the navigation pane.

8. The system of claim 7, further comprising a navigation service to couple data items displayed in the one or more columns within the column explorer display area of the user interface at the display device to corresponding displayable data items in the navigation pane.

9. The system of claim 8, further comprising navigation data that is bound to both the navigation pane and to the column explorer display area, the navigation data including a record of a plurality of most recently used data items, wherein each of the most recently used data items is identifiable by a corresponding link that is displayed within the navigation pane.

10. The system of claim 7, wherein the navigation pane further includes a second plurality of displayable data items representing a second set of nodes of the hierarchical data structure, wherein the navigation pane includes multiple levels of information where a second level of the multiple levels is indented with respect to a first level of the multiple levels, wherein the first level includes the plurality of displayable data items, and wherein the second level includes the second plurality of displayable data items representing the second set of nodes.

11. The system of claim 7, wherein a first link to a data item in a first column is displayed in a first location in the navigation pane associated with a first data item in the navigation pane and a second link to a second data item in a second column is displayed in a second location in the navigation pane associated with a second data item in the navigation pane.

12. The system of claim 7, wherein each of the one or more columns is adapted to enable a search of data items at a particular level of the hierarchical data structure.

13. The system of claim 7, wherein the navigation pane displays a selector that includes a plurality of subset selectors including at least one subset selector displayed proximate to the column explorer activation selector, and wherein the column explorer activation selector is proximate to the column explorer display area.

14. The system of claim 7, wherein the navigation pane includes an area for displaying a most recently used link, the most recently used link providing a direct link to a particular item within the column explorer display area, wherein the most recently used link is representative of the particular item within the column explorer display area that a user has most recently selected.

15. The system of claim 14, wherein the most recently used link is created automatically when a user selects the particular item of the hierarchical namespace and after a delay period expires.

16. The system of claim 7, wherein upon selection of the column explorer activation selector, application code invokes launch of the expandable column explorer logic, wherein actions that involve the navigation pane logic with respect to items within the expandable column explorer logic are synchronized using synchronization links, and wherein a navigation data storage stores data binding elements related to the expandable column explorer logic and the navigation pane logic.

17. The system of claim 16, wherein a most recently used item is stored in the navigation data storage and is retrievable by the navigation pane logic via a data binding to display a most recently used direct link within the navigation pane area, wherein the navigation data storage includes several items and associated recently used links.

18. The system of claim 7, wherein upon navigation to a data item in the one or more columns, a link to the data item is automatically added as a selectable link in association with one of the plurality of displayable data items in the navigation pane.

19. The system of claim 7, wherein a first of multiple selectable items in the navigation pane is associated with a first most recently used link and a second of the multiple selectable items in the navigation pane is associated with multiple most recently used links.
