我有一个vb.net表单,上面有一个文本框,设置为从数据库中自动完成自定义集合。当用户从自动完成列表中找到所需的值时,是否会触发事件?
答案 0 :(得分:7)
当用户按下列表中项目的Enter或Double Clicks时,Key.WownCode = 13会触发KeyDown事件。

在 * vb.net *
中尝试此文本框的未完成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
