'Declaration Public Overridable Property DropDownStyle As Infragistics.Win.DropDownStyle
public virtual Infragistics.Win.DropDownStyle DropDownStyle {get; set;}
The DropDownStyle property controls the interface that is presented to the user. When set to DropDown, the text portion is editable, and the control's value can be set to any string value.
When set to DropDownList, the control's value must correspond to an item in the dropdown list.
Note: The value of the DropDownStyle property also influences certain aspects of the keyboard behavior. For example, when the DropDownStyle property is DropDownList, pressing an alpha-numeric key results in the first item whose text begins with that character becoming selected.
