Click on headers (sort) to see events firing here or click to force sorting by "Freight" column

You can use the client-side ColumnSort event to fire a custom javascript event on sorting. For example:

<ClientSideEvents ColumnSort="columnSort" />

The event handler receives three parameters - (columnName, columnIndex, sortOrder).

You can also force sorting of a certain column by calling the javascript jqGrid method sortGrid(columnName, reload).

For details, please review the ASPX tab for code specifics.

Switch theme:

Theming is based on the very popular jQuery ThemeRoller standard. This is the same theming mechanism used by jQuery UI and is now a de-facto standard for jQuery based components. The benefits of using ThemeRoller are huge. We can offer a big set of ready to use themes created by professional designers, including Windows-like themes (Redmond), Apple-like theme (Cupertino), etc. In addition to that any jQuery UI controls on the same page will pick the same theme.

Last, but not least, you can always roll your own ThemeRoller theme, using the superb Theme Editor

To use a theme, simply reference 2 Css files in your Html <head> section - the ThemeRoller theme you wish to use, and the jqGrid own ThemeRoller Css file. For example (Redmond theme):

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