Hi,
I don't know why you need prev/next buttons when you have calendar as dropdown
and you can select any date from it!
Anyway, I think this will do exactly what you want:
<dx:aspxdateedit id="ASPxDateEdit1" runat="server" ClientInstanceName="myDateEdit" Date="02/02/2012 10:00:00">
</dx:aspxdateedit>
<dx:aspxbutton id="ASPxButton1" runat="server" autopostback="False" EnableClientSideAPI="True" Text="Previous date">
<ClientSideEvents click="function(s, e) {
myDateEdit.setDate(myDateEdit.getDate() - 1);
}" />
</dx:aspxbutton>
<dx:aspxbutton id="ASPxButton2" runat="server" autopostback="False" EnableClientSideAPI="True" Text="Next date">
<ClientSideEvents click="function(s, e) {
myDateEdit.setDate(myDateEdit.getDate() + 1);
}" />
</dx:aspxbutton>
BTW.
DevExpress have excellent
demos[

documentation[
