Grid Filtering

By default, the filtering functionality of the Kendo UI Grid for ASP.NET Core is disabled.

The filtering functionality of the Grid is controlled by the Filterable property:

    .Filterable() // Enables the Menu filter mode

The Grid filtering supports Menu and Row modes. The filter mode is configured through the Filterable->Mode property.

You can enable checkbox list filtering in the filter menu of the Grid HtmlHelper by specifying Columns -> Filterable -> Multi(true) setting for the relevant grid columns:

columns.Bound(p => p.UnitsInStock).Width(140).Filterable(ftb => ftb.Multi(true).CheckAll(true));

Each Filterable configuration of the columns allow setting custom DataSource:

columns.Bound(e => e.LastName).Width(220).Filterable(ftb => ftb.Multi(true)
    .DataSource(ds => ds.Read(r => r.Action("Unique", "Grid").Data("{ field: 'LastName' }")))
);            .ShowIndexes(true))
