在另一个组合框选定值的基础上设置组合框值-VB.NET [英] Set Combobox Value base on another Combobox Selected Value - VB.NET

问题描述

我有两个组合框。如果用户从第一个组合框中选择某个值，那么我希望第二个组合框自动更改并选择为其对应的值。

I have two comboboxes. If the user selects a certain value from the first combobox then I want the second combobox to automatically change and select to its corresponding value.

例如：

If Me.InstitutionAdvisoryFirmsComboBox1.SelectedValue = 3 Then 
     Me.WeightComboBox1.SelectedValue = 2

我也尝试过：

If Me.InstitutionAdvisoryFirmsComboBox1.SelectedText = "Internal Guidelines" Then                 
    Me.WeightComboBox1.SelectedText = "None"

有人可以帮忙吗？

推荐答案

//selected index changed event for the combo box 

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles InstitutionAdvisoryFirmsComboBox1.SelectedIndexChanged

    If Me.InstitutionAdvisoryFirmsComboBox1.SelectedIndex = 3 Then 
        If Me.WeightComboBox1.Items.Count >= 2 Then // make sure you are not accessing an index out of range
            Me.WeightComboBox1.SelectedIndex = 2
        End If
    End If

End Sub
