Filling a List from SQL query - what am I doing wrong?
I'm trying to fill a listbox with an sql query and it works great...except I want to have multiple things/columns per line.
This is what Ive got so far and it returns just the stock#'s to the listbox...how can add a few more things to each line like ,Year,Make,Model,Color
cmd.Connection = conn
cmd.CommandType = CommandType.Text
cmd.CommandText = "SELECT StockNumber,Year,Make,Mode
Try
cmd.Connection.Open()
dr = cmd.ExecuteReader
While dr.Read
lstStocknumberList.Items.A
End While
Catch ex As SqlException
MessageBox.Show(ex.Message
Finally
cmd.Connection.Close()
End Try

Assuming WinForms application, not ASP.NET.

Yes WinForms...
Ok did that but now how do I fill the list with the items....say record #1 contained |Stock#|Year|Make|Model|Co
how do I modify my listitems.add code to add the data?

thanks Chaosian but VB.net is giving me an error on
" DataAdapter is not defined" ...is that referring to...
Dim conn As New SqlConnection("My connection string ;")
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
also " DataBind is not a member of System.Windows.Forms.Listb
Thanks for your help!

oops figured out that 'DataAdapter' should be "SqlDataAdapter" sorry :) but still stumped on 'DataBind'
Doh! I'm in ASPX mode... apparently you don't need to call BindData at all.

hmm now in the list it shows 5 columns of "System.Data.DataRowView"
current code is...
Dim conn As New SqlConnection("Connection string...;")
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
cmd.Connection = conn
cmd.CommandType = CommandType.Text
cmd.CommandText = "SELECT StockNumber,Year,Make,Mode
Try
cmd.Connection.Open()
Dim adapt As SqlDataAdapter = New SqlDataAdapter(cmd)
Dim dt As New DataTable
adapt.Fill(dt)
With lstStocknumberList
.DataSource = dt
.MultiColumn = True
.ColumnWidth = 5
End With
Catch ex As SqlException
MessageBox.Show(ex.Message
Finally
cmd.Connection.Close()
End Try
current code is...
Dim conn As New SqlConnection("Connection string...;")
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
cmd.Connection = conn
cmd.CommandType = CommandType.Text
cmd.CommandText = "SELECT StockNumber,Year,Make,Mode
Try
cmd.Connection.Open()
Dim adapt As SqlDataAdapter = New SqlDataAdapter(cmd)
Dim dt As New DataTable

With lstStocknumberList
.DataSource = dt

Try setting the DisplayMember for the list box.
lstStockNumberlst.DisplayM
Then try setting it to show multiple columns (this is NOT documented):
lstStockNumberlst.DisplayM
lstStockNumberlst.DisplayM
Then try setting it to show multiple columns (this is NOT documented):
lstStockNumberlst.DisplayM
You're probably going to discover that you can't have different fields in your columns -- you'll need to go to a datagrid to do that...
