A JQ Grid is a light weighted open source grid developed in JavaScript Jquery to fill data from the database.

To download the JQ Grid js file go to the following site:

http://www.trirand.com/blog/?page_id=6.

Now I will create an ASP.Net application where I will display the record from an array through the JQ Grid.

Step 1:

In Visual Studio 2010 first create a simple ASP.Net web project named "JQgridapplication".

Step 2:

After that add the required JS file and folder for the JQ grid. The folder and file structure will look as shown in the following figure1 marked with red.

Figure 1:

Step 3:

Now create a folder named "UserControls" under the main project. After that create a user control named "Main.ascx" under the "UserControls" folder.

Step 4:

Now in the Main.ascx file first call all the related JQ Grid related js files.

<script src="../js/jquery-1.5.2.min.js" type="text/javascript"></script>
<script src="../js/i18n/grid.locale-en.js" type="text/javascript"></script>
<script src="../js/jquery.jqGrid.min.js" type="text/javascript"></script>
<script src="../Scripts/json2-min.js" type="text/javascript"></script>
After that for the JQ Grid paste The following code:

<script type="text/javascript">
$(document).ready(function () {
jQuery("#list1").jqGrid({
datatype: "local",
colNames: ['Inv No', 'Date', 'Client', 'Amount', 'Tax', 'Total', 'Notes'],
colModel: [
{ name: 'id', index: 'id', width: 60, sorttype: "int" },
{ name: 'invdate', index: 'invdate', width: 90, sorttype: "date" },
{ name: 'name', index: 'name', width: 100 },
{ name: 'amount', index: 'amount', width: 80, align: "right", sorttype: "float" },
{ name: 'tax', index: 'tax', width: 80, align: "right", sorttype: "float" },
{ name: 'total', index: 'total', width: 80, align: "right", sorttype: "float" },
{ name: 'note', index: 'note', width: 150, sortable: false }
],
multiselect: true,
rowNum: 10,
rowList: [5, 10, 20, 50, 100],
pager: jQuery('#pager1'),
sortorder: "desc",
viewrecords: true,
caption: "Manipulating Array Data"
});

var mydata = [
{ id: "1", invdate: "2007-10-01", name: "test", note: "note", amount: "200.00", tax: "10.00", total:
"210.00" },

{ id: "2", invdate: "2007-10-02", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },

{ id: "3", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" },

{ id: "4", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" },

{ id: "5", invdate: "2007-10-05", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },

{ id: "6", invdate: "2007-09-06", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" },

{ id: "7", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" },

{ id: "8", invdate: "2007-10-03", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },

{ id: "9", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" }

];

for (var i = 0; i <= mydata.length; i++)

jQuery("#list1").jqGrid('addRowData', i + 1, mydata[i]);

});
// });
</script>

Here I am defining the JQ Grid and binding it through an array.

So the whole code of the "Main.ascx " is:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Main.ascx.cs" Inherits="OneConsole.UserControls.Main" %><link href="../css/ui-darkness/jquery-ui-1.8.12.custom.css" rel="stylesheet" type="text/css" />
<link href="../css/ui.jqgrid.css" rel="stylesheet" type="text/css" />
<script src="../js/jquery-1.5.2.min.js" type="text/javascript"></script>
<script src="../js/i18n/grid.locale-en.js" type="text/javascript"></script>
<script src="../js/jquery.jqGrid.min.js" type="text/javascript"></script>
<script src="../Scripts/json2-min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
jQuery("#list1").jqGrid({
datatype: "local",

colNames: ['Inv No', 'Date', 'Client', 'Amount', 'Tax', 'Total', 'Notes']
colModel: [
{ name: 'id', index: 'id', width: 60, sorttype: "int" },
{ name: 'invdate', index: 'invdate', width: 90, sorttype: "date" }
{ name: 'name', index: 'name', width: 100 },
{ name: 'amount', index: 'amount', width: 80, align: "right", sorttype: "float" },
{ name: 'tax', index: 'tax', width: 80, align: "right", sorttype: "float" },
{ name: 'total', index: 'total', width: 80, align: "right", sorttype: "float" },
{ name: 'note', index: 'note', width: 150, sortable: false }
],
multiselect: true,
rowNum: 10,
rowList: [5, 10, 20, 50, 100],
pager: jQuery('#pager1'),
sortorder: "desc",
viewrecords: true,
caption: "Manipulating Array Data"
});

var mydata = [
{ id: "1", invdate: "2007-10-01", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" },

{ id: "2", invdate: "2007-10-02", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },

{ id: "3", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" },

{ id: "4", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" },

{ id: "5", invdate: "2007-10-05", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },

{ id: "6", invdate: "2007-09-06", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" },

{ id: "7", invdate: "2007-10-04", name: "test", note: "note", amount: "200.00", tax: "10.00", total: "210.00" },

{ id: "8", invdate: "2007-10-03", name: "test2", note: "note2", amount: "300.00", tax: "20.00", total: "320.00" },

{ id: "9", invdate: "2007-09-01", name: "test3", note: "note3", amount: "400.00", tax: "30.00", total: "430.00" }

];

for (var i = 0; i <= mydata.length; i++)

jQuery("#list1").jqGrid('addRowData', i + 1, mydata[i]);

});

// });

</script>
<asp:ScriptManager ID="ScriptManager1" runat="server"> <Services>
</Services>

</asp:ScriptManager>
<table id="list" ></table>
<div id="pager" ></div>
<br />
<br />

<table id="list1" ></table>

<div id="pager1" ></div>

Step 5:

Now in the "Default.aspx" we have to call the "Main.ascx" UserControl.

So the code is:

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeBehind="Default.aspx.cs" Inherits="OneConsole._Default" %>
<%@ Register TagPrefix="OneConsole" TagName="MainControl" Src="~/UserControls/Main.ascx" %><asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<h2>
OneConsole
</h2>
<OneConsole:MainControl ID="mainControl" runat="server" />
</asp:Content>

Step 6:

Now run the application. It will look like the following figure.

Conclusion: So in this example we have seen how to bind the value from an array to a JQ Grid.
