Assembly: DevExpress.ExpressApp.v23.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public IList CreateDataView(
    Type objectType,
    IList<DataViewExpression> expressions,
    CriteriaOperator criteria,
    IList<SortProperty> sorting
)

VB.NET

Public Function CreateDataView(
    objectType As Type,
    expressions As IList(Of DataViewExpression),
    criteria As CriteriaOperator,
    sorting As IList(Of SortProperty)
) As IList

Parameters

Name	Type	Description
objectType	Type	A Type of requested objects.
expressions	IList<DataViewExpression>	An IList<DataViewExpression> list that specifies data view column names and expressions used to compute column values. These column names can be used for sorting and filtering the data view via the criteria and sorting parameters.
criteria	CriteriaOperator	A CriteriaOperator object that specifies criteria associated with the data view.
sorting	IList<SortProperty>	An IList<SortProperty> collection whose elements identify the sorted columns within the data view.

Returns

Type	Description
IList	An IList object that returns a lightweight list of data records.

Remarks

This method does not return real objects. Instead, a lightweight read-only list of data records that can be viewed much more quickly than a real objects collection is returned.

This method result can be directly cast to XafDataView.
