Display Information In A Listbox From Selection Made In Datagridview?

Jun 26, 2009

I'm curently trying to get information displayed in a listbox from a selection made in a datagridview. For example a user selects an artist from the treeview control and it displays all the albums by that artist in the datagridview. Once a user selects an album all information for that album is displayed below the datagridview in either a listbox or listview control. I've tried dragging the conrols from the datasource and it' won't drag onto the listbox. What do I need to do to get it so that it will display album, artist and track information?

ListBox PreferredHeight - Make ListBox Calculate Correct Integral Height Before ListBox Is Made Visible

Nov 19, 2009

If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:

a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).

b) PreferredHeight does not not appear to give the correct integral of item heights.

Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

ListBox1.Visible = False
ListBox1.IntegralHeight = True

All ComboBoxes Updating When Selection Made

Mar 1, 2011

I have a relatively simple application that uses a series of combo boxes to ask questions. These combo boxes are bound to a table with 2 columns in it "RSN" and "RSN_ID". I'm using one table adapter to feed the form (and these boxes) once the main form is loaded. The problem I'm having is when I change one of the boxes, they all change to the same value, almost like they have the exact data source (which they do) but shouldn't you be able to make different selections even using the same table adapter? I have to run 20 queries at loadtime, or create 20 table adapters.

My current setup is like this:
Data Source: table that feeds the combobox
Display Member: RSN (from combo box table)
Value Member: RSN_ID(from combo box table)
Selected Value: Form's main binding source, unique to each combo box, where the selection is actually saved.

This works perfect when using one combobox, but as soon as I bound all of them I ran across this...

Asp.net - Creating A Dynamic Dropdown, After A Selection Has Been Made

Oct 6, 2011

I am trying to create a dynamic dropdown after a dropdown has been selested (in asp.net vb)

For example: I have a dropdown question that asks: What brand of car do you drive (Toyota, Ford, Honda, Nissan, Chevrolet)

When the brand is selected I want another dropdown to appear under it with new chocies

For example: If Nissan is chosen, the second dropdown will be populated (from the database) with (Altima, Maxima, etc...)

And in some cases I would like a text box to appear, but If I can figure out the dropdown portion, I am sure I can figure out the textbox.

Populate Textbox Based On ComboBox Selection Not Using Databinding

Apr 27, 2010

I have a form, frm1 w/a combobox, cboLocations, which is being populated using a sql string. There is also a frm2 w/a series of textboxes and other comboboxes. I want it so that once a selection is made from cboLocations, the textboxes and comboboxes on frm 2 are populated with the corresponding data. Here is what I have so far:

frm1:
Public Class frmLocations
Dim conn As New SqlConnection("Data Source=f03d3s-dev01; Initial Catalog=dos_track;User Id=vbuser; Password=tran3;")
Dim depot_refnbr As Integer
Private Sub frmLocation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
conn.Open()
[Code] .....

What's happening right now is that I make a selection from cboLocations on frm1 and click on the OK button, frm2 loads, but none of the textboxes are populating and one of the comboboxes, cboDepot, shows the different data when you click on the down arrow, but it's not displaying anything it its text field when frm2 loads.

VS 2010 Populate Textbox With Excel Data Based On Combobox Selection?

Nov 29, 2011

Visual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.

What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.

Calendar Selection Output In Listbox

Jan 16, 2009

I've been making a scheduling program using the calendar object.I can manage to select any date with a single click with a message box pop up entering a memo for the date selected. After pressing ok, the memo is displayed in a list box, with date.

1.Unfortunately the date is being displayed twice - perhaps because i used .selectedrange in the handler ? i would like it to be listed only once

2. the memo comes up on a separate line, ideally id like it to be displayed on the same line as the date.i tried ListBox1.Items.Add(whendate, memo) but it cant compile, so ive had to put each line in seperately

3. I would like to mark the sundays and national holidays in red color (the calendar is only set for a year so i dont mind doing them by hand, however the only tool i can find in the Monthcalendar1 properties is MonthlyBoldedDates, and no color assignment [code]

Cannot Display Database Selection In Listbox?

Aug 24, 2009

I am doing a lab where you have to connect to the database using the Database Configuration Wizard in Visual Basic (Visual Studio 2008). The database connection is there since the form will display the records.The problem is the user is supposed to be able to click on the combobox arrow to select a stock rating (high, low, etc) and then the listbox will display only the stocks with that rating. I thought this would work but nothing is showing up in the listbox.

' strSql is a SQL statement which selects all the fields from the Team database.
Dim strSql As String = "SELECT * FROM Stocks"
'strPath provides the database type and path of the Team database[code]...
