Click on a row to see all people the reports to this person




You can have any content as a child for any expandable row. In this example, we are doing a simple ajax back to the server to retrieve the details and photo of the respective Employee in the parent grid.

Please, refer to the ASPX and C# code tabs for additional details.

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" />
FirstName {0}
LastName {1}
Title {2}
Title of Courtesy {3}
Birth Date {4}
Hire Date {5}
Address {6}
City {7}
Postal Code {8}
