Vb.net 组合框自动完成

Question

我有一个带有 DropDownStyle = Simple 的 ComboBox 并将其绑定(bind)到 DataSet。我想要的是:当我输入“a”时，我希望我的 ComboBox 仅显示以字母“a”开头的项目，只是字典程序。

我尝试了 AutoComplete 属性，但它只显示 DropDown 这不是我想要的

这是我的代码:

Private Sub TICKETING_FORM_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        da.Fill(ds, "STYLE")
        bs.DataSource = ds.Tables("STYLE")

        With Style_ComboBox
            .DataSource = bs
            .DisplayMember = "STYLE"
            .ValueMember = "STYLE"
            .AutoCompleteMode = AutoCompleteMode.Suggest
            .AutoCompleteSource = AutoCompleteSource.ListItems
        End With

    End Sub

您需要为自动完成设置这些属性

ComboBox1.AutoCompleteMode = AutoCompleteMode.Append
ComboBox1.DropDownStyle = ComboBoxStyle.DropDown
ComboBox1.AutoCompleteSource = AutoCompleteSource.ListItems


Private Sub TICKETING_FORM_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        da.Fill(ds, "STYLE")
        bs.DataSource = ds.Tables("STYLE")

        With Style_ComboBox
            .DataSource = bs
            .DisplayMember = "STYLE"
            .ValueMember = "STYLE"
            .DropDownStyle = ComboBoxStyle.DropDown
            .AutoCompleteMode = AutoCompleteMode.Suggest
            .AutoCompleteSource = AutoCompleteSource.ListItems
        End With

    End Sub
