The GridControl supports displaying tabbed content in row details. This topic describes how to enable displaying detail data in tabbed layout.

Enabling the master-detail representation

Do the following to enable details:

1. Ensure the master GridControl‘s TableView.AllowMasterDetail option is enabled (enabled by default).
2. Provide the TabViewDetailDescriptor detail descriptor to the grid’s GridControl.DetailDescriptor property.
3. Provide a collection of nested detail descriptors to the TabViewDetailDescriptor‘s MultiDetailDescriptor.DetailDescriptors property. Each such nested detail descriptor is displayed in an individual tab.

4. Configure the nested detail descriptors. Refer to the following topics to learn how to configure different types of detail descriptors:

   • data grid in detail;
   • custom content in details;
   • data dependent details;

Example

The code sample below demonstrates how to organize detail data in a tabbed layout using the TabViewDetailDescriptor. The TabViewDetailDescriptor displays the following tabs:

• Details within a nested grid. These details are rendered using the DataControlDetailDescriptor
• Details visualized with the ChartControl. These details are rendered using ContentDetailDescriptor which displays the data template with the ChartControl.
