By default the ComboBox
is with AutoSize = true
which means that the height of the ComboBox is determined by the size of the font that is used (see property Font). In this mode only the width can be set.
If you wish to set arbitrary size first set AutoSize to false. Know that in case you shrink the size of the combo the text and button will be just clipped.
To have correct height, better use AutoSize = true
and remove the vertical Paddings
(in design-time from the Combo's ActionList click on "Edit UI elements" and select in the tree RadTextBoxElement
If you wish even smaller ComboBox just use smaller font (set it for the control - from the property grid in VisualStudio).
Hope that helps.
