Question

我设法让我的ToolstripComboBox显示数据源（字典）。

但是现在我想将一个DataBinding添加到SelectedValue属性中，但我没有工作。

对于普通的ComboBox，它可以工作：/ ..

我的代码： tscbb_Test.ComboBox.DataBindings.Add（＆＃34; SelectedValue＆＃34;，My.Settings，＆＃34; mySettings＆＃34中的设置;）

有人可以帮忙吗？

我刚尝试了这个，它对我来说很有效：

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Dim table As New DataTable

    With table.Columns
        .Add("ID", GetType(Integer))
        .Add("Name", GetType(String))
    End With

    With table.Rows
        .Add(1, "Peter")
        .Add(2, "Paul")
        .Add(3, "Mary")
        .Add(4, "John")
    End With

    Me.BindingSource1.DataSource = table
    Me.BindingSource2.DataSource = table

    With Me.ToolStripComboBox1.ComboBox
        .DisplayMember = "Name"
        .ValueMember = "ID"
        .DataSource = Me.BindingSource1
        .DataBindings.Add("SelectedValue", My.Settings, "ToolStripSelectedValue")
    End With

    With Me.ComboBox1
        .DisplayMember = "Name"
        .ValueMember = "ID"
        .DataSource = Me.BindingSource2
        .DataBindings.Add("SelectedValue", My.Settings, "FormSelectedValue")
    End With
End Sub

我可以运行项目，在每个ComboBox中选择一个不同的项目，关闭项目，再次运行它，然后再次选择我之前选择的项目，表示设置必须已保存。

我刚尝试了两个Keys类型的设置，并按预期工作：

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Dim keys = [Enum].GetValues(GetType(Keys))

    Me.BindingSource1.DataSource = keys
    Me.BindingSource2.DataSource = keys

    With Me.ToolStripComboBox1.ComboBox
        .DataSource = Me.BindingSource1
        .DataBindings.Add("SelectedItem", My.Settings, "ToolStripSelection")
    End With

    With Me.ComboBox1
        .DataSource = Me.BindingSource2
        .DataBindings.Add("SelectedItem", My.Settings, "FormSelection")
    End With
End Sub
