我有一个问题,ComboBox控件将在调整大小时更改其Text值.以下是我编写的一些示例代码:

Option Explicit On

Public Class FMain  
    Private Sub FMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        uxComboBox.DropDownStyle = ComboBoxStyle.DropDown  
        uxComboBox.AutoCompleteSource = AutoCompleteSource.ListItems  
        uxComboBox.AutoCompleteMode = AutoCompleteMode.Suggest  

        ComboTest()  
    End Sub  

    Private Sub ComboTest()  
        Dim value As String = "6"  

        uxComboBox.Text = String.Empty  
        uxComboBox.Items.Clear()  

        uxComboBox.Items.AddRange(New String() {"4 9/16", "6 9/16", "7 9/16", "8 9/16"})  

        Dim index As Integer = uxComboBox.FindStringExact(value)  
        If uxComboBox.SelectedIndex  index Then  
            uxComboBox.SelectedIndex = index  
        End If  

        If uxComboBox.SelectedIndex = -1 AndAlso _
           Not String.Equals(uxComboBox.Text, …
