CollectionSourceBase.EndUpdateCriteria() Method

Ends update of the Collection Source’s collection criteria and applies it.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v19.2.dll

Declaration

C#

public void EndUpdateCriteria()

VB.NET

Public Sub

Remarks

Generally, the EndUpdateCriteria/CollectionSourceBase.EndUpdateCriteria methods should be used when you need to perform several modifications of the Collection Source’s collection CollectionSourceBase.Criteria. After calling the EndUpdateCriteria method, you can change the criteria as required. The criteria will not be applied to the Collection Source’s collection until you call the EndUpdateCriteria method. The following code snippet illustrates this:

C#

//...
collectionSource.BeginUpdateCriteria();
collectionSource.Criteria["1"] = CriteriaOperator.Parse("...");
collectionSource.Criteria["2"] = CriteriaOperator.Parse("...");
collectionSource.EndUpdateCriteria();
//...

VB.NET

'...
collectionSource.BeginUpdateCriteria()
collectionSource.Criteria("1") = CriteriaOperator.Parse("...")
collectionSource.Criteria("2") = CriteriaOperator.Parse("...")
collectionSource.EndUpdateCriteria()
'...
