I am developing a form for entering data into Excel and for some of the
fields have dates as values. I really like the built-in date and time
picker control for this, except that I want to be able to change the
background colour of the part of the control that looks like a combo
box. And that is simply not possible with the standard date and time
picker. How can I get around this problem
I have been trying to create a custom control to emulate the date and
time picker by combining a standard combo box with a hidden month view
control that becomes visible when the user presses the dropdown button
of the command box, but have been having a lot of trouble with this.

Hi,
Thank you for contacting Microsoft ISV Partner Support.
Your two question is about the vba control Date Picker Control.
1) how to change the back color of Data Picker text box
Based on my experience, we just can change the CalendarBackColor, not the textbox.
Data Picker is just a control for VBA, so it has not so many rich properties.
2) what’s the "send to back" button, could you please specify it

After further investigation, the engineer has determined that this is a bug.
This issue that the "send to back" does not work on the control "Date Picker Control is a bug and I have submitted it to the product team. Unfortunately we have no workarounds that the product team can offer us.
Sorry I don't have a solution to share with you, but appreciate that you brought the issue to our attention.
