Hi VEDA VIDVA NARAYANAN SATTANATHAN,
Thank you for contacting us. You can resize the drop-down list of RadDropDownButton by setting the MinimumSize
properties. Unfortunately, there will be no scroll provided after the drop-down is resized. Thus you will only have access to the visible items. Our team apologizes for the inconvenience.
The work around that we can suggest is to use RadComboBox instead of RadDropDownButton. The RadComboBox has MaxDropDownItems
property that allows you to set the visible items. Scroll will be automaticly provided, so you will have access to all of the items in the RadComboBox.
I hope this helps. If you have further issues, do not hesitate to contact us back.
