Hi –
I think i’m overlooking something relatively simple:
I’m trying to use the renderer property within a DropDownList widget to achieve a 2-row table for each dropdown item (very similar to the demo shown on jqwidgets website at ‘demos/jqxdropdownlist/rendering.htm’).
This particular dropDownList widget is populated with JSON data from a separate PHP file — the PHP file is coded fine and generates the appropriate array string.
However, I cannot seem to figure out how to get the renderer property to display the JSON data properly. If I remove the renderer property from the widget initiation, I get a perfectly functioning dropDownList, but without the 2-row table rendering (so therefore I know the PHP linkage is working OK). Yet with the renderer property written as in the code below, I can get the widget to display, but the dropdown is completely empty. I think my error is in how I’m defining variables within the renderer’s assigned function, but I’ve tried a bunch of options and the best I can get is a two-table row that gives me a bunch of “undefined” items in the dropdown…. Thoughts?

var source =
{ datatype: “json”,
datafields: [
{ name: ‘code’ },
{ name: ‘text’ }
],
url: ‘data.php’};
var dataAdapter = new $.jqx.dataAdapter(source);$(“#dropdownlist”).jqxDropDownList(
{
source: dataAdapter,
theme: theme,
width: 100,
height: 28,
displayMember: ‘code’,
valueMember: ‘code’,
renderer: function (index, label, value) {
var datarecord = source[index];
var table = ‘<table><tr><td>’ + datarecord.code + ‘</td></tr><tr><td>’ + datarecord.text + ‘</td></tr></table>’;
return table;
}
});Hi jcf378,
That part: var datarecord = source[index]; is the issue. According to me, it should be: var datarecord = dataAdapter.records[index];
