Remarks

Use the PopupExcelFilterGrouping property to group filter values in the current column’s filter menu by another column. The code snippet below groups cities by countries.

C#
VB.NET

csharp

colCity.OptionsFilter.PopupExcelFilterGrouping = "Country;City";

colCity.OptionsFilter.PopupExcelFilterGrouping = "Country;City"

As a result, filter values are displayed in a tree structure.

In the case of a Code First data source, you can annotate data fields with the FilterGroup attribute using the same syntax in the attribute parameter.

C#
VB.NET

csharp

[Utils.Filtering.FilterGroup("Country;City")]
public string City { get; set; }

<Utils.Filtering.FilterGroup("Country;City")>
Public Property City As String
