DropDownButtonDisplayStyle Property (UltraComboEditor)

Gets/sets the display style for the control's dropdown button.
Syntax
'Declaration
 
Public Property DropDownButtonDisplayStyle As Infragistics.Win.ButtonDisplayStyle
public Infragistics.Win.ButtonDisplayStyle DropDownButtonDisplayStyle {get; set;}
Remarks

The UltraComboEditor control provides the ability to control whether the dropdown button is displayed.

When set to Always (default), the dropdown button is always displayed, as is the case with an intrinsic ComboBox control.

When set to Never, the dropdown button is never displayed. Note that this does not affect whether the list portion of the control can be displayed.

When set to OnMouseEnter, the dropdown button is displayed when the cursor passes into the boundaries of the control, and hidden when it passes outside.

Example
This example uses the control's DropDownStyle property to disallow typing values into the edit portion, and sets the DropDownButtonDisplayStyle so that the dropdown button does not appear.

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinEditors

    Private Sub SetupDropDownStyles()

        '	Set the DropDownStyle to DropDownList so the control's
        '	value is restricted to items that appear in the list portion
        Me.UltraComboEditor1.DropDownStyle = DropDownStyle.DropDownList

        '	Set the DropDownButtonDisplayStyle proeprty to Never, so the dropdown
        '	button does not appear. Note that the dropdown list can still be displayed
        '	by pressing the F4 key
        Me.UltraComboEditor1.DropDownButtonDisplayStyle = ButtonDisplayStyle.Never

    End Sub
using System.Diagnostics;
using Infragistics.Win;
using Infragistics.Win.UltraWinEditors;

		private void SetupDropDownStyles()
		{
			//	Set the DropDownStyle to DropDownList so the control's
			//	value is restricted to items that appear in the list portion
			this.ultraComboEditor1.DropDownStyle = DropDownStyle.DropDownList;

			//	Set the DropDownButtonDisplayStyle proeprty to Never, so the dropdown
			//	button does not appear. Note that the dropdown list can still be displayed
			//	by pressing the F4 key
			this.ultraComboEditor1.DropDownButtonDisplayStyle = ButtonDisplayStyle.Never;

		}
