I recently was tasked with moving the tooltip to the right of the control instead of it being on top on the RadDateTimePicker. When the tooltip is on top, the tooltip tends to cover up the field above it when the user types, which is a problem. I was able to go into expression blend, make a copy of the DateTimePicker's theme, and move the popup to pop to the right instead of above. However, the control isn't blue anymore. I am using the Office_Blue theme, but it turns into a black and white theme any time I change the style of a control. Is there a way to keep the popup to the right of the control, and keep the control blue? I would rather not change the style in the silverlight theme as described here... http://www.telerik.com/help/silverlight/common-styling-apperance-modifying-built-in-theme.html because with every new release from telerik, I'll have to make the changes again. Thank you.
