Namespace: DevExpress.Xpf.Bars
Assembly: DevExpress.Xpf.Core.v19.2.dll
Declaration
Property Value
| Type | Description |
|---|---|
| Boolean | true if each reference to a data object in an BarItemLinkHolderBase.ItemLinksSource for this BarItemLinkHolderBase should generate a unique BarItem; otherwise, false. The default is false. |
Remarks
While generating a layout via the BarItemLinkHolderBase.ItemLinksSource property, if you insert a reference to a single data object into multiple ItemLinksSources for different BarItemLink holders, each holder will contain a corresponding BarItemLink. However, these links will refer to a single BarItem. This default behavior prevents issues related to using two-way bindings.
However, such behavior also prevents you from defining different item templates (or styles) for the same data object. If different templates (styles) need to be defined, you can do one of the following:
- Clone data objects;
- Revert to the old behavior by setting the ItemLinksSourceElementGeneratesUniqueBarItem property to true for your BarItemLinkHolderBase.
