LookUpEditBase.FilterCriteria Property

Gets or sets the filter expression applied to the editor’s bound source. This is a dependency property.

Namespace: DevExpress.Xpf.Editors

Assembly: DevExpress.Xpf.Core.v19.1.dll

Declaration

C#

public CriteriaOperator FilterCriteria { get; set; }

VB.NET

Public Property FilterCriteria As CriteriaOperator

Property Value

Type	Description
CriteriaOperator	A CriteriaOperator descendant that represents a filter expression.

Remarks

When the Filter Expression is applied, the LookUpEdit control filters its data items before displaying them.

Use the FilterCriteria property to set a Filter Expression.

When the editor is bound to a collection of complex type objects (every object has its own properties), the filter expression can be applied as follows: "Contains([SomeProperty], '123')"

Use the DisplayColumn value to create a filter expression when the editor is bound to a collection of simple objects:

C#

LookUpEdit.FilterCriteria = new FunctionOperator(
  FunctionOperatorType.EndsWith, 
  new OperandProperty("DisplayColumn"), 
  new OperandValue("ask0")
);

VB.NET

LookUpEdit.FilterCriteria = New FunctionOperator(
  FunctionOperatorType.EndsWith, 
  New OperandProperty("DisplayColumn"), 
  New OperandValue("ask0"))

For more information on how to create filter expressions, see Criteria Language Syntax and Creating Criteria.
