Select grid page size
Select page size options

You can customize the functionality and UI of the grid pager using the PagerSettings set of properties. You can set the PagerSettings.PageSize property to the numbers of row you wish to see in a page (default is 10).

You can also choose the options end-users see in the page-size dropdown. This is a comma separated list of values in the PagerSettings.PageSizeOptions string property. For example, to see 5 options 5,10,15,25,30 you just have to set PagerSettings.PageSizeOptions to the string [5,10,15,25,30]

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" />
