Gets or sets a value indicating whether the control should resize to avoid showing partial items.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When this property is set to true, the control automatically resizes to ensure that an item is not partially displayed. If you want to maintain the original size of the ComboBox based on the space requirements of your form, set this property to false. If the ComboBox does not contain any items, this property has no effect.
Setting the DropDownHeight property resets the property to false.
If the DrawMode property is set to OwnerDrawVariable, this property has no effect.
