Navigator

The Navigator is a user interface feature that allows easy accessibility to record actions such as Find or Edit. 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 jqGrid. jqGrid provides icon button graphics for the predefined actions.

The full set of predefined actions are:

1) 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.

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.

* 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.

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.

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.

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.

HTML definition

...
<body>
...
   <table id="list"></table> 
   <div id="gridpager"></div> 
...
</body>

JavaScript code

<script>
...
jQuery("#grid_id").jqGrid({
...
   pager : '#gridpager',
...
});
jQuery("#grid_id").navGrid('#gridpager',{parameters},prmEdit, prmAdd, prmDel, prmSearch, prmView);
...
</script>

Using the new API

<script>
...
jQuery("#grid_id").jqGrid({
...
   pager : '#gridpager',
...
});
jQuery("#grid_id").jqGrid('navGrid','#gridpager',{parameters},prmEdit, prmAdd, prmDel, prmSearch, prmView);
...
</script>

or in chained mode

<script>
...
jQuery("#grid_id").jqGrid({
...
   pager : '#gridpager',
...
}).navGrid('#gridpager',{parameters}, prmEdit, prmAdd, prmDel, prmSearch, prmView);
...
</script>

Where:

  • grid_id - the id of the already constructed jqGrid.
  • gridpager - the id of the navigation bar
  • parameters - an array of settings, defined below
  • prmEdit, prmAdd, prmDel, prmSearch, prmView are objects which holds the parameters and events for a particular action in Form editing

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.

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

The code below defines a edit button with id myedit.

<script>
...
jQuery("#grid_id").jqGrid({
...
   pager : '#gridpager',
...
}).navGrid('#gridpager',{}, {id:'myedit'});
...
</script>

If a class ui-state-disabled is added to some of these buttons we disable not only the button, but the click action too

Parameters

When we use the Navigator the following options are included from the language file.

If you want to change the text that appears when a user hovers over a button, simply replace the text in the title string in the bottom part of the code below. For example: hover text for the view button is supplied by viewtitle: “View selected row”

$.jgrid = {
...
   search : {
     caption: "Search...",
     Find: "Find",
     Reset: "Reset",
     odata : ['equal', 'not equal', 'less', 'less or equal','greater','greater or equal', 'begins with','does not begin with','is in','is not in','ends with','does not end with','contains','does not contain'],
     groupOps: [ { op: "AND", text: "all" }, { op: "OR", text: "any" } ],
     matchText: " match",
     rulesText: " rules"
   },
   edit : {
     addCaption: "Add Record",
     editCaption: "Edit Record",
     bSubmit: "Submit",
     bCancel: "Cancel",
     bClose: "Close",
     saveData: "Data has been changed! Save changes?",
     bYes : "Yes",
     bNo : "No",
     bExit : "Cancel",
  },
  view : {
    caption: "View Record",
    bClose: "Close"
  },
  del : {
    caption: "Delete",
    msg: "Delete selected record(s)?",
    bSubmit: "Delete",
    bCancel: "Cancel"
  },
  nav : {
    edittext: "",
    edittitle: "Edit selected row",
    addtext:"",
    addtitle: "Add new row",
    deltext: "",
    deltitle: "Delete selected row",
    searchtext: "",
    searchtitle: "Find records",
    refreshtext: "",
    refreshtitle: "Reload Grid",
    alertcap: "Warning",
    alerttext: "Please, select row",
    viewtext: "",
    viewtitle: "View selected row"
  },

The above example enables the grid view mode form enabling closing of the modal dialog with ESC key and sets advanced searching. It also disables the delete action.

Hi,

I am having trouble formatting the navGrid for over 999 records. When I get records over 999 it is displaying as ex: “View 1 - 20 of 2 150”, but I would like to show either “View 1 - 20 of 2150”. or “View 1 - 20 of 2,150”. Don't want to display blank space at thousands position. Either it should be a comma (,) or no space. How can I format this to not to show any extra space or use comma (,).

Thanks

Steve Busko, 2010/11/12 20:55

I just solved this myself yesterday. You need to edit the grid.locale-en.js (or whichever language file(s) you are using) and search for: thousandsSeparator:” ” and then simply replace the ” ” (space) with whatever delimiter you want. One last note, there are three instances of this variable, I don't know the differences between each, I just changed them all. Enjoy - Steve

Chris Mathews, 2012/08/17 04:49

Easier way to do this without having to modify any of the jqgrid distributed files is: $.jgrid.formatter.integer.thousandsSeparator='';

slam, 2010/12/20 08:15

This is the quesion what i faced.

I want to delete a item but there is no item checked.it will pop a box and shows “Warning! Please Selet Row”,there is only a close button in the top right corner but I want custom a confirm button in this box.

Can it likes info_dialog ways,just configure with “buttons : []”

Could you tell me what should i do for it.

Thanks

Steffen Mutter, 2011/01/23 00:47

How can I make use of 'editfunc': I want to display a datetimepicker in the row with the id 'spieltermin'… Unfortunalely there's no example how to get this done.

Sergey, 2011/02/03 20:00

I'm using both inline jqGrid editGridRow button onclick method and edit button in the grid. When default grid button is pressed, that is ok with afterSubmit check - it returns success. But when editGridRow method is called - there is no way to see if there was problems or not. Please clarify my delusion!

wayne, 2011/03/03 11:32

who can tell me where is the “bulid in add function”???

Paul Speranza, 2011/05/06 05:21

Is there a way to override the ajax beforeSend and complete events in the delete dialog options? Also in the other CRUD dialog options. Thanks, Paul

sue, 2011/05/06 17:14

I downloaded jqgrid4.0. I can't get pager's left and right arrow to display. Do I need to download image from somewhere else?

Diosney Sarmiento Herrera, 2011/07/05 04:56

Hi!

It could be great if there is another default action(or specific to the Add action) in navigator that clones a selected row and then send the data to the server or open an Add form with the cloned data for edition.

Regards.

saravanan, 2011/09/13 17:21

Hi is there a way to add mouseover event to add in the navigator pager button

Problem:- loadonce:true 'disables' pagination by making datatype to 'local' from 'json' if loadonce:false pagination will work fine but filteration(search) will not happen.

So is there a way to enable 'mouseover' event on 'pager' button. through which i can trigger the loadonce:false and reset the 'datatype' as 'json'. And in loadcomplete i ll set loadonce:true which in turn makes datatype local and filteration works.

Jeremy, 2011/12/21 08:28

Hi, how can i set the actions during runtime? For example, when the no row is selected, i only wan to display the “Add”. If a row is selected, two new actions: “Edit” and “Delete” will be visible. Cheers!
