Popup Resize Support in WPF AutoComplete (Classic)

28 May 20211 minute to read

AutoComplete allows you to resize the drop-down list popup using the CanResizePopup property. If this property is set as True the thumb will be shown in the right bottom corner of the drop-down list which adjusts the height and the width of the popup at runtime. If this property is set as False, the visibility of the thumb will be collapsed and you will not be able to resize the popup at runtime.
