Remarks

Generally, the BeginUpdateCriteria()/EndUpdateCriteria methods should be used when you need to perform several modifications of the Collection Source’s collection CollectionSourceBase.Criteria. After you call the BeginUpdateCriteria() 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()
