 ====== Navigator ======
-Navigator is a method that can add predefined actions like editing, adding, deleting, and searching.  It is also possible to add [[custom buttons]] with custom actions.
+The Navigator is a user interface feature that allows easy accessibility to record actions such as Find or Edit.
-The built in navigator should be applied to the pager element. In other words, the pager element should be defined. The built in navigator actions correspond to the form editing actions. For more information and details refer to [[Form Editing]].
+The user can activate a grid action by pressing the appropriate icon button in the Navigation layer.
+Developers can create custom actions, or they can use any of the six predefined actions that come with [[http://www.trirand.com/jqgridwiki/doku.php?id=start|jqGrid]]. jqGrid provides icon button graphics for the predefined actions.
+The full set of predefined actions are:
+) Add New Row, 2) Edit Selected Row, 3) View Selected Row, 4) Delete Selected Row, 5) Find Records, and 6) Reload Grid
+The image below shows these six buttons in the bottom-left.
+{{:wiki:navigator1.png|}}
+<note tip>The Navigation layer doesn't have to be located on the bottom:  it can be positioned inside the grid window. Also, the Navigation layer itself is optional and can be removed.</note>
+<note tip>  * You can also add your own [[custom buttons]] with custom actions to the Navigation layer.
+  * You can also change the text that appears when a user hovers over a button (see below: that text is found in the language file)
+ * Navigator buttons can be positioned on the left, middle, or right side. </note>
+=====How to Use:=====
+The Navigator is a jqGrid method.  It's activated and configured by extending your main grid function, as shown in the code examples below. The full list of all possible configurable parameters is listed in the table below.

 ===== Definition =====
-In order to use the navigator the Form Edit module , Common module and optionally the search and Modal modules, should be checked when you download the grid. Refer to [[Download]] section.

     * //parameters// - an array of settings, defined below

+<note tip>Additionally to every particular module defined with prmEdit, prmAdd, prmDel, prmSearch, prmView a id parameter can be passed in order to identify the id of the button in the Navigator. If this id is not defined we use the combination of a prefix and the grid id. See below.</note>
+If the id of the button is not set we use the following rule: \\
+For the add button we use "add_" + the id of the grid \\
+For the edit button we use "edit_" + the id of the grid \\
+For the delete button we use "del_" + the id of the grid \\
+For the view button we use "view_" + the id of the grid \\
+For the search button we use "search_" + the id of the grid \\
+For the refresh button we use "refresh_" + the id of the grid \\
