[RESOLVED] Combobox ListIndex

I am trying to have the index value of a selected item in a combobox returned to a variable. Then, if the variable = 1 (which would be the index of th second item in the combobox), I want a groupbox to be hidden (be invisible) on the form. Here is my code...Getting an error that says:

'ListIndex' is not a member of 'System.Windows.Forms.ComboBox'

Code:

---

Private Sub cbxAccounts_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Dim selection As Integer = CInt(cbxAccounts.ListIndex)
        If selection = 1 Then gbxCheck.Hide()
    End Sub

---

Exactly as the error message: The ComboBox class has no member named "ListIndex". Have you looked to see what members the ComboBox class has and which one does what you want? All you have to do is type the dot after the variable name and Intellisense will show you a list of all members, and if you want more information you can simply consult the documentation.

I found what I need, but for some reason the Groupbox is not being hidden when the item is selected in the combobox. back to the book I go.

Which item are you selecting? If you're looking for the first item then that would be at index 0, not index 1. All lists in .NET are 0-based, so I suspect that you're using VB6 example code.

I am selecting the second item.

This works now. It took some work, but I got it going. Here is the code:

Code:

Private Sub cbxAccounts_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbxAccounts.SelectedIndexChanged

        ' Hide "Check" Groupbox when "Savings" is selected from "Accounts" Combobox
        Dim selection As String = cbxAccounts.SelectedItem
        If selection = "Savings" Then gbxCheck.Visible = False Else gbxCheck.Visible = True

    End Sub
