Assembly: DevExtreme.AspNet.Core.dll

Declaration

public GanttColumnHeaderFilterBuilder DataSource(
    Func<DataSourceFactory, OptionsOwnerBuilder> configurator
)

Parameters

To specify a data source, use a lambda expression. The lambda parameter is a DataSourceFactory class instance that provides methods to configure data access from different sources.

The following example demonstrates how to bind a header filter to an API controller:

Razor C#

@(Html.DevExtreme().Gantt()
    .Columns(columns => {
        columns.Add().HeaderFilter(filter => filter
            .DataSource(ds => ds.Mvc()
                .Controller("MyDataController")
                .LoadAction("Get")
                .Key("ID")
            )
        );
    })
)
