Question

我收到此错误“运营商'='未定义类型'CivilStatus'并输入'整数'。”

代码：

Private Sub cboCivilStatus_SelectedValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboCivilStatus.SelectedValueChanged

    If cboCivilStatus.SelectedValue = 2 Then
        dtpDateMarried.Enabled = True
    Else
        dtpDateMarried.Enabled = False
    End If

End Sub

Answer 1

好的，你应该尝试使用Combobox SelectedIndexChanged事件

Private Sub cboCivilStatus_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cboCivilStatus.SelectedIndexChanged
        If cboCivilStatus.Text = "2" Then
            dtpDateMarried.Enabled = True
        Else
            dtpDateMarried.Enabled = False
        End If

    End Sub

Answer 2

看起来SelectedValue包含类CivilStatus的对象。如果您要查找所选项目的索引，请改为使用cboCivilStatus.SelectedIndex属性：

If cboCivilStatus.SelectedIndex = 2 Then

但是如果您需要CivilStatus的属性，则需要检查该属性，例如

If CType(cboCivilStatus.SelectedValue, CivilStatus).MyIntProperty = 2 Then

vb.net combobox selectedvalue事件错误
