Question

我的表格上有一个组合框。这与一个表格相关联，该表格包含员工姓名和该人员的员工参考。

Combobox显示所有员工姓名和选择应该创建 staffRef 的值，我希望能够选择名称，并且 StaffRef 被填充到文本框。

到目前为止，我只能得到 StaffRef 这个词。

这是我的代码，希望你能帮忙！

        Private Sub frmAddCar_Load(sender As System.Object, e As System.EventArgs)
        Handles MyBase.Load


        'TODO: This line of code loads data from the 'namesstolenpool' table and drops
         it into the combobox(Driver_Name).

        Dim table As DataTable
        table = BusinessData.VerifierLogic.Load("namesstolenpool", 
        New Dictionary(Of String, Object))
        Driver_name.DataSource = table
        Driver_name.DisplayMember = "displayname"
        Driver_name.ValueMember = "staffref"

    End Sub

    'This should display the "value" of the combobox in the textbox. 


    Private Sub Driver_name_SelectedIndexChanged(sender As System.Object
    , e As System.EventArgs) Handles Driver_name.SelectedIndexChanged

        TextBox1.Text = Driver_name.ValueMember

    End Sub

End Class

Answer 1

尝试这样

 Private Sub Driver_name_SelectedIndexChanged(sender As System.Object
    , e As System.EventArgs) Handles Driver_name.SelectedIndexChanged

        TextBox1.Text = Driver_name.SelectedItem("staffref")

    End Sub

从ComboBox读取值并将其放入文本框中
