在vb.net自动完成的文本框的建议

问题描述

我实现自动完成在vb.net文本，但有一个问题，当用户键入的东西在文本框中自动完成建议列表闪烁并消失一样，如果重点变成

I implemented auto complete in vb.net textbox , but there is an issue that when user types something in text box the auto complete suggestion list blinks and disappears like if the focus changed

这里是code：

        Dim Bl As New ItemBL
        Dim suggestions = DAL.DisplayLikeNameList(Trim(MyTextBox.Text))
        Dim MySource As New AutoCompleteStringCollection()
        MySource.AddRange(suggestions.ToArray)

        With MyTextBox
            .AutoCompleteCustomSource = MySource
            .AutoCompleteMode = AutoCompleteMode.Suggest
            .AutoCompleteSource = AutoCompleteSource.CustomSource
        End With
    End If

我相信，在MDI窗体的问题，因为它具有以上code后执行定时code：

I believe the problem in Mdi form because it has timer code executed after the above code :

 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    LblDateAndTime.Text = Now
End Sub

注：自动完成code是不是在MDI窗体子窗体执行，你有什么建议继续建议列表粘在文本框中输入用户书写？

Note: the auto complete code is executed in a child form not in the Mdi Form , what do you suggest to keep suggestions list "sticky" as the user writing in the text box ??

推荐答案

我解决了问题，

这code写于
    KEY_UP 事件
但现在我写在 Text_Changed 事件和它的工作

This Code was written in Key_Up eventbut now I wrote it in Text_Changed Event and it worked
