Hello,

it would be a very useful information when subscribing to the DataBindingComplete Command of a DataGrid to know whether for example a filter, sort, grouping had changed.

Currently, it is an internal Property

Regards

Provide an option to set explicit style to the grouping panel, for example expose GroupingPanelStyle property. 

Currently, the option is using an implicit style targeting the DataGridGroupingPanel

<Style TargetType="telerik:DataGridGroupingPanel">
    <Setter Property="BackgroundColor" Value="Red"/>
    <Setter Property="HeaderText" Value="Hello to group"/>
    <Setter Property="CornerRadius" Value="10"/>
    <Setter Property="BorderThickness" Value="2"/>
    <Setter Property="BorderColor" Value="Blue"/>
</Style>
