NuGet Package: DevExpress.Win.Navigation

Declaration

public int DropDownRows { get; set; }

VB.NET

<DXCategory("Behavior")>
<DefaultValue(7)>
Public Property DropDownRows As Integer

Property Value

Type	Default	Description
Int32	7	The number of visible rows in the dropdown window.

Remarks

The DropDownRows property specifies the number of rows (items) displayed in the dropdown when it is opened for the first time. Use the DropDownItemHeight property to specify a custom height of rows.

If the total number of records in the data source is greater than DropDownRows, the lookup displays the vertical scroll bar.

If the value of the DropDownRows property is greater than the total number of records in the data source, you can enable the UseDropDownRowsAsMaxCount property to adjust the height of the dropdown and avoid white space.

Note

Setting the DropDownRows and PopupWidth properties has no effect if the dropdown is already open.
