SftBox/OCX 5.0 - Combo Box Control

SftBoxDropDown.Dropped Property

Defines whether the drop down portion is shown/hidden.

Syntax

Get

Put

object

A SftBoxDropDown object.

Boolean

Defines whether the drop down portion is shown/hidden.

Comments

The Dropped property defines whether the drop down portion is shown/hidden.

The drop down portion can only be visible when the control has the input focus. Setting the Dropped property when the control does not have the input focus will set the input focus to the control and display the drop down portion.

The DropDown.RollUp method can also be used to hide the drop down portion.

This property cannot be used with a simple combo box.

Examples

VB.NET

    e.allowedEffects = vbDropEffectCopy Or vbDropEffectMove
    Dim textData As String = comboSource.get_Cell(comboSource.Items.Selection, 0).Text
    e.data.SetData(textData, SftOLEClipboardConstants.sftCFText)
End Sub

Private Sub comboTarget_OLEDragOver(ByVal sender As Object, ByVal e As AxSftBoxLib50._ISftBoxEvents_OLEDragOverEvent) Handles comboTarget.OLEDragOver
    If e.state = SftBoxOLEDragOverConstants.enterSftBox Then
        ' Show the drop down portion
        comboTarget.DropDown.Dropped = True
    ElseIf e.state = SftBoxOLEDragOverConstants.leaveSftBox Then
        ' Hide the drop down portion with a delay, in case the
        ' user is moving from/to the static or drop down portion
        comboTarget.DropDown.RollUp(500)  ' 1/2 second
    End If
