LookUpEditBase.IncrementalFiltering Property

Specifies whether to enable the incremental filtering feature. This is a dependency property.

Namespace: DevExpress.Xpf.Editors

Assembly: DevExpress.Xpf.Core.v24.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public bool? IncrementalFiltering { get; set; }

VB.NET

Public Property IncrementalFiltering As Boolean?

Property Value

Type	Description
Nullable<Boolean>	true, to enable the incremental filtering; otherwise, false.

Remarks

If the IncrementalFiltering property is set to true, the editor filters its dropdown list for matches to the input value.

The LookUpEditBase.IsCaseSensitiveFilter property specifies whether the editor should distinguish between upper and lower case characters while looking for the matching item.

Handle the SubstituteDisplayFilter event if you need to customize the way the editor filters data.

When the editor’s LookUpEditBase.DisplayMember/LookUpEditBase.ValueMember properties are defined, users can only select objects from the ItemsSource collection. To allow users to type in the edit box, set the LookUpEditBase.AutoComplete property to true and/or BaseEdit.ValidateOnTextInput property to false.
