Header and Footer in UWP AutoComplete (SfTextBoxExt)

You can provide header and footer views in a suggestion list in AutoComplete by enabling the ShowDropDownHeaderView and ShowDropDownFooterView properties.

Header content

You can provide the header content at the top of the suggestion box. The DropDownHeaderView property is used to set content to the header. The height of the header in the AutoComplete can be adjusted using the DropDownHeaderViewHeight property.

You can provide the footer content at the bottom of the suggestion box. The DropDownFooterView property is used to set the content of the footer. The height of the header in the AutoComplete can be adjusted using the DropDownFooterViewHeight property.
