Similar to Excel - RadPivotGrid could have an area, where you can select some filter/group descriptions.

Currently, the string format (used in the cells generated for the  from the DateTimeGroupDescription) is determined automatically based on the selected Step (Day, Month, etc.). Add an option to easily set custom string format.

At this moment, you can change the format only if you create a custom description and override a considerable amount of code. This is shown in the following SDK example: https://github.com/telerik/xaml-sdk/tree/master/PivotGrid/CustomDateTimeGroupDescription

add a textbox which allows users to find matching distinc values when using report filters. Very valuable if you are dealing with many distinct values. 

Bug can be observed in Pivot Grid => Olap Sorting example in  the most recent demo.

Sadly i do not know what this menu is called in english (and the demo cannot change language) so here is a screenshot

Set it to 'Equal' 'Lisa Cai'




If you hit ok and refresh, all values are gone.
Weirdly if you change it to not equal, you still get zero results

If you open a label filter dialog from the RadPivotFieldList control for a DateTime field and choose the "is between" or "is not between" operator from the combobox, you will notice that the RadDateTimePicker controls used to filter the dates very small. In this case, the empty value placeholder is clipped and if you choose any dates they are clipped too.

To work this around, you can increase the dialog's width when it opens. You can do this with the RoutedDialogEvents.RequestDialog event.

public MainWindow()
{
	InitializeComponent();
	pivotFieldList.AddHandler(RoutedDialogEvents.RequestDialog, new EventHandler<DialogHostingRequestEventArgs>(this.OnDialogHostRequested), true);
}

private void OnDialogHostRequested(object sender, DialogHostingRequestEventArgs e)
{
	var labelDialog = e.DialogInfo.Content as LabelFilterDialog;
	if (labelDialog != null)
	{
		var w = labelDialog.ParentOfType<RadWindow>();
		w.Width = 500;
	}
} 

It seems that the option to turn of sums has no effect for hirachie columns.
No matter if this option is checked or not, they do not disappear.

It works on regular columns.
