# Column Group Footer

When the grid is grouped, the columns can display a footer with information about the column data [aggregates](https://www.telerik.com/blazor-ui/documentation/components/grid/grouping/aggregates) and some custom text/logic. The template is strongly typed and exposes the available aggregates values.

The `GroupFooterTemplate` context exposes the current group value through its `Value` property. It does not expose the name of the field that defines the group. To get the group field name, read the current [Grid state](https://www.telerik.com/blazor-ui/documentation/components/grid/state) and inspect the `Member` property of the `GroupDescriptor`:

```CS.skip-repl
private TelerikGrid<MyModel> GridRef { get; set; }

private string GetGroupFieldName()
{
	return GridRef.GetState().GroupDescriptors.FirstOrDefault()?.Member;
}
```

When the Grid has multiple grouping fields, inspect the full `GroupDescriptors` collection. Its order represents the grouping order; the `GroupFooterTemplate` context does not identify which group descriptor is currently rendering.
