DataControlDetailDescriptor.ItemsSourcePath Property

Gets or sets the detail grid’s data binding by specifying the path relative to the master grid’s records.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v24.1.Core.dll

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public string ItemsSourcePath { get; set; }

VB.NET

Public Property ItemsSourcePath As String

Property Value

Type	Description
String	A string value specifying the data binding path relative to the master grid’s records.

Remarks

When working with an Entity Framework source, this property value should be set to the name of the Navigation Property that represents the required data relation. Similarly, when working with master-detail data created in code, the ItemsSourcePath property is set to the name of the property that references the aggregated collection.

You can use ItemsSourcePath in combination with the DataControlDetailDescriptor.ItemsSourceValueConverter property. If these two properties are insufficient for your data binding scenario, use the DataControlDetailDescriptor.ItemsSourceBinding property.

Example

This example creates tabbed details (TabViewDetailDescriptor) in the GridControl. The Orders tab displays the GridControl (DataControlDetailDescriptor), and the Notes tab displays a memo field (ContentDetailDescriptor).

View Example: Display Detail Content in Tabs
