Demonstrates how to bind jqGrid to declarative SqlDataSource control. The only thing you need to do is to set the DataSourceID property of jqGrid to the ID of the respective SqlDataSource control. Note that there is not even a single line of code in the C# file (click on the C# tab) - everything is done declaratively.

Also, all major grid features like sorting (click on a column header), searching (click on the server icon on the bottom toolbar), paging, etc work as well by default -- no need to code anything.

Column settings can be customized using the collection. Columns are automatically created when you associate a declarative datasource with the grid at design time.

You can tweak various column properties, like HeaderText (in order to set column header text), DataFormatString (to control formatting of the cells), Width (set column with in pixels), etc.

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" />
