Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

public void SortBy(
    string columnFieldName,
    GridColumnSortOrder sortOrder
)

Parameters

Name	Type	Description
columnFieldName	String	Specifies the name of the data source field that supplies data for the processed column. If the component does not contain the column that corresponds to the specified data field, an exception occurs.
