Public Methods

Method	Description
AddBookmark ( string name, ESRI extent ) : void	Adds a named Map.Extent (aka. a bookmark) into the DataGrid sub-component of the Bookmark Control. The AddBookmark Method adds a named Map.Extent (aka. a bookmark) into the ObservableCollection(Of Bookmark.MapBookmark) object. The ObservableCollection(Of Bookmark.MapBookmark) object is internally bound to the DataGrid sub-component in the Bookmark Control. Use the Bookmark.Bookmarks Property to obtain the ObservableCollection(Of Bookmark.MapBookmark) object. There are two input parameters for the AddBookmark Method: name and extent.The name is the human readable string that defines a geographic extent on the Map. The extent is the Map.Extent that corresponds to item name in the ObservableCollection. The functionality of the AddBookmark Method is comparable to when a user of a client application types a string into the Textbox sub-component of the Bookmark Control and clicks the + button, causing the named Map.Extent (aka. a bookmark) to appear in the DataGrid. It should be noted that the AddBookmark Method IS NOT the Event for the + button of the Bookmark Control. To change the core behavior of any of the sub-components and their appearance of the Bookmark Control (including the + button), developers must modify the Control Template in XAML and the associated code-behind file. The easiest way to modify the UI sub-components is using Microsoft Expression Blend. Then developers can delete/modify existing or add new sub-components in Visual Studio to create a truly customized experience. A general approach to customizing a Control Template is discussed in the ESRI blog entitled: Use control templates to customize the look and feel of ArcGIS controls. An example of modifying the Control Template of the Bookmark control to provide an alternate set of functionality that automatically populates several named Map.Extent (aka. a bookmark) values via the AddBookmark Method is provided in the code example section of this document.
ClearBookmarks ( ) : void	Clears the bookmarks.
DeleteBookmarkAt ( int index ) : void	Deletes a bookmark from the DataGrid sub-component of the Bookmark Control at a specified index. The DeleteBookmark Method deletes a single Bookmark from the ObservableCollection(Of Bookmark.MapBookmark) object. The ObservableCollection(Of Bookmark.MapBookmark) object is internally bound to the DataGrid sub-component in the Bookmark Control. Use the Bookmark.Bookmarks Property to obtain the ObservableCollection(Of Bookmark.MapBookmark) object. Unlike the Bookmark.AddBookmark Method which takes a name and a Map.Extent as parameters to add items into the ObservableCollection, the DeleteBookmark Method requires an Integer index value to remove an item from the ObservableCollection. No Method exists in the ArcGIS API for Silverlight ArcGIS Runtime SDK for WPF ArcGIS Runtime SDK for Windows Phone to remove an item from the ObservableCollection by its name. The top-most Bookmark listed in the DataGrid sub-component of the Bookmark Control is the zero (0) item index value. There is no Property/Method in the ArcGIS API for Silverlight ArcGIS Runtime SDK for WPF ArcGIS Runtime SDK for Windows Phone for the Bookmark Control to obtain the selected index value(s) of the DataGrid sub-component from client user interaction. However, developers can change the core behavior of any of the sub-components and their appearance of the Bookmark Control (including the obtaining selection index values of the DataGrid sub-component) by modifying the Control Template in XAML and the associated code-behind file. The easiest way to modify the UI sub-components is using Microsoft Expression Blend.

An example of modifying the Control Template of the Bookmark control to obtain the selection index value of the DataGrid sub-component in the Bookmark Control is provided in the code example section of this document.
OnApplyTemplate ( ) : void	When overridden in a derived class, is invoked whenever application code or internal processes (such as a rebuilding layout pass) call M:System.Windows.Controls.Control.ApplyTemplate.

Method Details

AddBookmark() public method

Adds a named Map.Extent (aka. a bookmark) into the DataGrid sub-component of the Bookmark Control.

The AddBookmark Method adds a named Map.Extent (aka. a bookmark) into the ObservableCollection(Of Bookmark.MapBookmark) object. The ObservableCollection(Of Bookmark.MapBookmark) object is internally bound to the DataGrid sub-component in the Bookmark Control. Use the Bookmark.Bookmarks Property to obtain the ObservableCollection(Of Bookmark.MapBookmark) object.

There are two input parameters for the AddBookmark Method: name and extent.The name is the human readable string that defines a geographic extent on the Map. The extent is the Map.Extent that corresponds to item name in the ObservableCollection.

public AddBookmark ( string name, ESRI extent ) : void
name	string	Display name (aka. named Map.Extent or bookmark).
extent	ESRI	The Map.Extent of the bookmark.
return	void

ClearBookmarks() public method

Clears the bookmarks.

public ClearBookmarks ( ) : void
return	void

DeleteBookmarkAt() public method

Deletes a bookmark from the DataGrid sub-component of the Bookmark Control at a specified index.

The DeleteBookmark Method deletes a single Bookmark from the ObservableCollection(Of Bookmark.MapBookmark) object. The ObservableCollection(Of Bookmark.MapBookmark) object is internally bound to the DataGrid sub-component in the Bookmark Control. Use the Bookmark.Bookmarks Property to obtain the ObservableCollection(Of Bookmark.MapBookmark) object.

public DeleteBookmarkAt ( int index ) : void
index	int	The index value of the bookmark to remove from the ObservableCollection.
