Remove footer for nested groups

[Dmitriy]

In my RadGridView I group data by two columns: first by column1 and then by column2. When I set ShowGroupFooters="true" I end up with two footers - one for column1 and another for column2. How can I hide footers for the nested groups (over column2) and leave only footers for the groups over column1?

thank you

Hello Dmitriy,

The desired behavior can be achieved by the use of RadGridView's GroupFooterRowStyleSelector property. Here is how you can define it:

public class GroupFooterRowStyleSelector : StyleSelector
{
    public override Style SelectStyle(object item, DependencyObject container)
    {
        IGroup group = item as IGroup;

        if (group != null)
        {
            if (group.ParentGroup != null)
            {
                return NestedGroupStyle;
            }
            else
            {
                return NormalGroupStyle;
            }
        }

        return null;
    }

    public Style NestedGroupStyle { get; set; }
    public Style NormalGroupStyle { get; set; }
}

<my:GroupFooterRowStyleSelector x:Key="GroupFooterRowStyleSelector">
    <my:GroupFooterRowStyleSelector.NestedGroupStyle>
        <Style TargetType="telerik:GridViewGroupFooterRow">
            <Setter Property="Visibility" Value="Collapsed"/>
        </Style>
    </my:GroupFooterRowStyleSelector.NestedGroupStyle>
    <my:GroupFooterRowStyleSelector.NormalGroupStyle>
        <Style TargetType="telerik:GridViewGroupFooterRow">
            <Setter Property="Visibility" Value="Visible" />
        </Style>
    </my:GroupFooterRowStyleSelector.NormalGroupStyle>
</my:GroupFooterRowStyleSelector>

<telerik:RadGridView GroupFooterRowStyleSelector="{StaticResource GroupFooterRowStyleSelector}" />

Please let me know if such an approach would work for you.
