Set Listbox Value

[Derek Hart]

How can I set the listbox value and retrieve a listbox value with just text?
I have filled the listbox with items in the items collection property (very
simple, just one column of text items).

I will have the text from a database and I know it is in the list. How can I
set it and retrieve it?

Do I need to loop the listbox to find matching text and set that
selectedindex to true.

Any sample code would be appreciated to get the text and set the text.

ListBox has FindString and FindStringExact methods.
Here's a sample to get started:

Private Sub Button1_Click(B yVal sender As Object, ByVal e As System.EventArg s) Handles Button1.Click
ListBox1.Items. Clear()
ListBox1.Items. Add("Banana")
ListBox1.Items. Add("is a")
ListBox1.Items. Add("fruit")
ListBox1.Items. Add("but")
ListBox1.Items. Add("monkey")
ListBox1.Items. Add("is an")
ListBox1.Items. Add("animal")
End Sub

Private Sub Button2_Click(B yVal sender As System.Object, ByVal e As System.EventArg s) Handles Button2.Click
Dim ThisIndex As Integer
ThisIndex = ListBox1.FindSt ringExact("monk ey")
If ThisIndex >= 0 Then
MessageBox.Show (ListBox1.Items (ThisIndex).ToS tring, _
"ListBox", _
MessageBoxButto ns.OK, _
MessageBoxIcon. Information)
ListBox1.Select edIndex = ThisIndex
ListBox1.Items( ThisIndex) = "donkey"
End If
End Sub

Listbox has a SelectedValue property. I don't know how it behaves if
the Listbox allows multiple items to be selected.

Re: Set Listbox Value

Derek,

In the same way as a Combobox

Create a collection by instance a datatable which is the most simple to use
with a listbox

Set that as the DataSource
Set one column to the displaymember
Set another column to the valuemember

You are ready
