  • 0

My goal is to inline edit cells in a data grid using JQuery and JqGrid. I got the grid to populate based on an ajax request and json reponse. Unfortunately I can’t get the cells to become editable when clicking on rows.

I tried both Chrome and Safari and did two days of research and still no luck. The links I used below didn’t help:

http://trirand.com/blog/jqgrid/jqgrid.html

http://www.trirand.net/demoaspnetmvc.aspx

Following the tutorials I added an onRowSelect event that would call editRow and set the value to true. However it never works and I can’t figure out why.

Any help would be greatly appreciated.

Code:

<html>
<head>
    <title>Test</title>

    <link rel="stylesheet" type="text/css" href="ui.jqgrid.css"/>
    <link rel="stylesheet" type="text/css" href="jquery-ui-1.8.2.custom.css"/>

    <style type="text/css">
    html, body {
        margin: 0;
        padding: 0;
        font-size: 75%;
    }
    </style>

    The main error in your code is:

    • you have to include editable: true property in the columns which you need to edit.

    Additionally you should do following changes in the code:

    • you should include <!DOCTYPE html ...> line before <html> which declare the dialect of HTML/XHTML which you use. If you use HTML5 dialect the line will be just <!DOCTYPE html>. In you case it seems can be the line <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> which corresponds XHTML 1.0 Strict. See the documentation for more details.
    • I recommend you reduce the number of global variables. The variable lastSelection and the function editRow should be just in outer scope of onSelectRow. So you can move there inside of $(document).ready(function() {/*here!!!*/}); block. I would recommend you better to use anonymous functions and place the code of editRow directly in the code of onSelectRow. By the way you can use $(this) instead of $("#list") inside of onSelectRow. It makes the code a little bit quickly and improves the maintenance of the code because you can easier cut & paste the code fragments.
    • you should never use prefixes like http://localhost:8080/ in the Ajax requests (see url and editurl options). Instead of that you should use url:'/jblog/messages' or url:'jblog/messages' URLs. Access to another server as the current server from which the current page are loaded or access of another port is prohibited because of same origin policy of Ajax.
    • I recommend you always use gridview: true jqGrid options which can improve performance of the grid.
