In this post, we will show you how to display the jQuery Grid widget inside a Popup by using the DropDownButton widget.

1. Include the necessary JavaScript and CSS files.
<link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" /><script type="text/javascript" src="../../scripts/jquery-1.7.2.min.js"></script><script type="text/javascript" src="../../jqwidgets/jqxcore.js"></script><script type="text/javascript" src="../../jqwidgets/jqxdata.js"></script><script type="text/javascript" src="../../jqwidgets/jqxbuttons.js"></script><script type="text/javascript" src="../../jqwidgets/jqxscrollbar.js"></script><script type="text/javascript" src="../../jqwidgets/jqxmenu.js"></script><script type="text/javascript" src="../../jqwidgets/jqxgrid.js"></script><script type="text/javascript" src="../../jqwidgets/jqxgrid.selection.js"></script><script type="text/javascript" src="../../jqwidgets/jqxdropdownbutton.js"></script>
2. Add one DIV tag for the DropDownButton and another DIV tag inside for the Grid.
<div id="jqxdropdownbutton"> <div style="border: none;" id="jqxgrid">
3. Create a JavaScript function that will generate and return an array of sample data that we will load into the Grid.
function generatedata(rowscount) { // prepare the data
var data = new Array();
if (rowscount == undefined) rowscount = 100;
var firstNames =
[
"Andrew", "Nancy", "Shelley", "Regina", "Yoshi", "Antoni", "Mayumi", "Ian", "Peter", "Lars", "Petra", "Martin", "Sven", "Elio", "Beate", "Cheryl", "Michael", "Guylene" ];
var lastNames =
[
"Fuller", "Davolio", "Burke", "Murphy", "Nagase", "Saavedra", "Ohno", "Devling", "Wilson", "Peterson", "Winkler", "Bein", "Petersen", "Rossi", "Vileid", "Saylor", "Bjorn", "Nodier" ];
var productNames =
[
"Black Tea", "Green Tea", "Caffe Espresso", "Doubleshot Espresso", "Caffe Latte", "White Chocolate Mocha", "Caramel Latte", "Caffe Americano", "Cappuccino", "Espresso Truffle", "Espresso con Panna", "Peppermint Mocha Twist" ];
var priceValues =
[
"2.25", "1.5", "3.0", "3.3", "4.5", "3.6", "3.8", "2.5", "5.0", "1.75", "3.25", "4.0" ];
for (var i = 0; i < rowscount; i++) {
var row = {};
var productindex = Math.floor(Math.random() * productNames.length);
var price = parseFloat(priceValues[productindex]);
var quantity = 1 + Math.round(Math.random() * 10);
row[
"id"] = i;
row[
"available"] = productindex % 2 == 0;
row[
"firstname"] = firstNames[Math.floor(Math.random() * firstNames.length)];
row[
"lastname"] = lastNames[Math.floor(Math.random() * lastNames.length)];
row[
"productname"] = productNames[productindex];
row[
"price"] = price;
row[
"quantity"] = quantity;
4. Create a new dataAdapter with 100 data records.
var data = generatedata(100);var source =
{
localdata: data,
datatype:
"array"};
var dataAdapter = new $.jqx.dataAdapter(source);
5. Initialize the DropDownButton by selecting the ‘jqxdropdownbutton’ DIV tag and calling the jqxDropDownButton constructor.
$("#jqxdropdownbutton").jqxDropDownButton({ width: 150, height: 25});
6. Initialize the Grid and set its source property to point to the data adapter.
$("#jqxgrid").jqxGrid({
width: 550,
source: dataAdapter,
columns: [
{ text:
'First Name', columntype: 'textbox', datafield: 'firstname', width: 90 },
{ text:
'Last Name', datafield: 'lastname', columntype: 'textbox', width: 90 },
{ text:
'Product', columntype: 'dropdownlist', datafield: 'productname', width: 180 },
{ text:
'Quantity', datafield: 'quantity', width: 70, cellsalign: 'right' },
{ text:
'Price', datafield: 'price', cellsalign: 'right', cellsformat: 'c2' }
7. We want to update the DropDownButton’s text when the user selects a Grid row. In order to achieve that, we will bind to the Grid’s ‘rowselect’ event and will
call the DropDownButton’s ‘setContent’ function to set the displayed text.
$("#jqxgrid").bind('rowselect', function (event) { var args = event.args;
var row = $(
"#jqxgrid").jqxGrid(
'getrowdata', args.rowindex);
var dropDownContent =
'<div style="position: relative; margin-left: 3px; margin-top: 5px;">' + row['firstname'] + ' ' + row['lastname'] + '</div>';
$(
"#jqxdropdownbutton").jqxDropDownButton(
'setContent', dropDownContent);
});
$(
"#jqxgrid").jqxGrid(
'selectrow', 0);
