[VB.net] Populate textboxes from listview selected items

[escuro]

Hi All.

I have a Form with listview of customer name. e.g. AAA, BBB, CCC, DDD, EEE. etc And 3 textboxes.

I want to be able to populate the textboxes when the user selects a customer. For example: If User selects AAA, textbox1.text = AAA, then if User selects CCC, textbox2.text = CCC etc.

I tired: (in a button on click event)
TextBox1.Text = Listview1.SelectedItems(0).Text
TextBox2.Text = Listview1.SelectedItems(1).Text
TextBox3.Text = Listview1.SelectedItems(2).Text

But this only works if the user selects 'all' 3 customers at once. I want to allow the User to populate each textboxes depending on how many they select eg. 'Upto' 3 customers .

Any ideas how i can achieve this?

Many Thanks in Advance.

The way I would go about doing this would be to have a counter which starts at 1.
Then in your button click event you would check what the counter was if its 1 then you would put the current selecteditem text into textbox1, if the counter was 2 then into textbox2 and I think you can guess where if the counter is 3

So your code might look similar to this

Public Class Form1

    Private counter As Integer

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If ListView1.SelectedItems.Count = 1 Then
            Select Case counter
                Case 1
                    TextBox1.Text = ListView1.SelectedItems(0).Text
                Case 2
                    TextBox2.Text = ListView1.SelectedItems(0).Text
                Case 3
                    TextBox3.Text = ListView1.SelectedItems(0).Text
            End Select
            counter += 1

            'This bit of code is so that you loop round and start at 1 again
            If counter > 3 Then
                counter = 1
            End If
        Else
            MsgBox("You must select an item in order to continue")
        End If
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        counter = 1
    End Sub

End Class

I've gone with the idea that you probably only want one thing selected at once, so you would probably want the listviews MultiSelect property set to false for this.

Anyway I hope that helps you
