.net - 当用户从自动完成文本框中选择任何项目时触发的事件？

Question

当用户从自动完成中选择任何项目时，VB.NET 中是否会触发任何事件TextBox？

下面是我的代码：

Private Sub txtFilterBy_TextChanged(ByVal sender As Object, ByVal e As EventArgs) Handles txtFilterBy.TextChanged
    txtSearch("Select Name From items", txtFilterBy)
End Sub

Public Sub txtSearch(ByVal strsql As String, ByVal textboxName As TextBox)
    con.ConnectionString = constr
    Excercise_Add.con.Open()
    Dim namesCollection As New AutoCompleteStringCollection()
    cmd = New MySqlCommand(strsql,con)
    da.SelectCommand = cmd
    read = cmd.ExecuteReader()
    While (read.Read)
        namesCollection.Add(read(0).ToString())
    End While
    textboxName.AutoCompleteMode = AutoCompleteMode.Suggest
    textboxName.AutoCompleteCustomSource = namesCollection
    textboxName.AutoCompleteSource = AutoCompleteSource.CustomSource
    con.Close()
End Sub
