    I checked the whole forum, didn't find solutions.
    I knew it's possible to show the group.key in header, but is it possible to show the group.key in footer?
    I tried many ways but failed. Attached is my requirement.

    Hello,

    In the GroupFooterTemplate you do not have access to the GroupViewModel but only to the results from the defined AggregateFunction: the Caption, FormattedValue, Value. What you can do is the define a FirstFunction AggregateFunction and then predefine the GroupFooterTemplate like so:

    <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}">
        <telerik:GridViewDataColumn.GroupFooterTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding FormattedValue.Name}"/>
            </DataTemplate>
        </telerik:GridViewDataColumn.GroupFooterTemplate>
        <telerik:GridViewDataColumn.AggregateFunctions>
            <telerik:FirstFunction/>
        </telerik:GridViewDataColumn.AggregateFunctions>
    </telerik:GridViewDataColumn>
     
    Will this work for you?
