trouble having ddlselection information display in seperate listbox

[joelk]

I have a dropdownlist with different products in it. I also have a ListBox below it that needs to contain product information depending on which selection is chosen.

How can I program the ListBox to display the description of a selected product with VB?

The dropdownlist is not configured to a datasource, it just has three products in it.

I know this question is easy, but I still need a little back up.

dropdownlist is an asp.net web control, is this an asp.net project?

Yes, sorry I think I may have posted it in the wrong section. Just now realized

Not a problem, thread moved.

For DropDownList control set AutoPostBack property to True if you want it to postback on selection change.
Doubleclick the control to generate the event handler for default event SelectedIndexChanged, here you can place this code:

Me.Label1.Text = "description " & Me.DropDownList1.SelectedValue

What is the Me. command?
Ok, so for example I would type

 Me.ListBox1.Text = "type description here" & Me.DropDownList1.SelectedValue

But how would I make it for all three different selected values?

 Me.ListBox1.Text = "type description here" & Me.DropDownList1.SelectedValue[0]
Me.Listbox1.Text = "type description here" & Me.DropdownList1.SelectedValue[1]
etc 
etc.

?

Me

There is only one SelectedValue, and it is the string value of the choice made.

I would use the Select Case statement, though you could use the If-Then-Else statement also.
Select...Case Statement (Visual Basic)
If...Then...Else Statement (Visual Basic)
