CategoricalAxis, LabelFormat and LabelTemplateSelector problem

[Jonathan]

Hello,

I have a problem with the horizontal axis of my RadCartesianChar when I change the period of my statistics:

The period is a complete month but I display only the day (dd) on horizontal axis.

The template selector allow me to display differently the type of day (normal, today, week end, holiday).

The first month all is correct but when I change the month, the SelectTemplate method of DateTypeTemplateSelector is not call again. So the template don't change with the new axis value of the month.

But if I display not only the day (dd) but the complete day (dd/MM/yyyy) on LabelFormat all works fine.

So I think that the SelectTemplate method of DateTypeTemplateSelector is call only when the displayed value is different.
But me I need o display only the day (dd).

Can you help me please. Thank you in advance and sorry for my bad English.

Kind regards,

Jonathan
