Data Bound To ListBox - Display Two Data Items As A Single Item?

May 7, 2012

I have an Address Book project with a listbox. The listbox is bound to the database via the little arrow pop-up box in the corner of the listbox. I have the DisplayMember set to FirstName, and obviously only display the First Name of the contact in the ListBox. Is there an easy way to change it so that it displays the First and Last names? I can't change the binding because I need it to get the ID of the record selected.Here's the basis of my code...

Private Sub MainForm_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'CompanyDataSet.Contacts' table. You can move,

ToolStrip ComboBox Using Data Bound Item?

May 4, 2009

I have created a search/query facility after watching one of Beth Messi's videos. I notice that we can convert the textboxes on the auto generated search toolstrip to buttons, comboxes, etc. So, when we wanna search for a data in the datagridview, we enter a keyword. I wonder if it is possible to change the textboxes to comboboxes and make it bind to the datasources, so that users can use the drop down, instead of typing?

Delete An Item From A Collection That Is Data Bound To A GridView?

Jul 22, 2011

I am creating a simple website using the language of VB.NET, I am having trouble with one part at the moment and could really use some help.

At the moment I have items that are stored in a database, when the homepage loads these items are added to a Gridview which allows the user to select the items they wish to add to their shopping cart. Once an item is selected from the gridview it is added to a collection. That collection is then added to a Session. This is the code I have for completing that task.[code]...

Access To Bound Data Items From A Textbox / When Text Box Is Not On Form

Dec 20, 2010

In my application, I have a data bound form using a binding control (built by the wizard). The application has one primary data screen plus a few more on tabcontrol subscreens.Picture for example that the tabcontrol has two tabs, tab1 and tab2.When the form is displayed, tab1 is visible.Now picture the form or window split in half the top part of the form has a few textbox controls bound to the data and there are a few textbox controls in the lower half of the screen on tab1 of tabcontrol1.There are a few textbox controls on tab2 as well.When the form displays, I can access any of the .text properties of any of the textbox's that I can see on the form and in tab1 of the tabcontrol.BEFORE tab2 is chosen or even, I need to get some of the data from the .text property on a textbox control that is on tab2.I have tried to get the data but as far as VB is concerned, it does not appear to be there UNTIL tab2 is displayed.

To prove this, I put a command button on the form and it simply does this: MSGBOX (mytext box33. text)mytextbox33 is a databound control on tab2 of the tabcontrol1.tab2 is not in focus and apparently, neither is the data.how can I read the .text property of a textbox that is on a form but the form (or tab) is not in focus?

VS 2008 Getting The Selected Values Of A Listbox That Is Data-bound?

Sep 25, 2009

Im having a problem getting the selected values of a listbox that is data-bound..

vb.net
Do Until CType(Ctrl, ListBox).SelectedIndices.Count = 0
For Each Index In CType(Ctrl, ListBox).SelectedIndices

[code]....

The error message says... "Operator '&' is not defined for type 'DataRowView' and string " "." And the only way I can get it to work is to pull out the & operator and change that line of code to this.

vb.net
'FROM THIS:
TableData.Miscellaneous += CType(Ctrl, ListBox).SelectedValue & " " 'Errors HERE

[code]....

The SelectedItem text shows up in the controls current state while debugging, correctly.. but after I finish the execution it shows up as "System.Data.DataRowView"?

Asp.net - Invalidate A Single Data Item In The .net Cache In VB

Jun 3, 2010

I have the following VB.NET code to set and read objects in cache on a per user basis (i.e. a bit like session)

Public Shared Sub CacheSet(ByVal Key As String, ByVal Value As Object)
Dim userID As String = HttpContext.Current.User.Identity.Name
HttpContext.Current.Cache(Key & "_" & userID) = Value
End Sub

[Code]....

I use these functions to hold user data that I don't want to access the DB for all the time. However, when the data is updated, I want the cached item to be removed so it get created again.

How do I make an Item I set disappear or set it to NOTHING or NULL?

Multiple Data Items In Single Field?

Apr 30, 2009

What I'm trying to do - VB 2005 express and sql 2005 express editions - Trying to set up just a basic hardware/software inventory program. As is I've got separate tables for computer and software licenses...with ComputerID and LicenseID primary keys respectively...where I'm bumping into walls is that I wanted to be able to link them together with a foreign key, for example the computer record would have a foreign key for LicenseID and when a license would get installed the ID would go in and there'd be a nice pretty link. However I run into scenarios where a computer might not have any software installed...or might have more than 1 software item. Or a single software item may be installed on 1 computer, multiple computers, or nowhere. It possible to have that single foreign key field link to multiple records from the opposite table?

What was originally suggested to me was to have a 3rd table called Installations. It'd have 3 rows...one named InstallationID as the primary key, and 2 foreign key rows named ComputerID and LicenseID that linked to the other tables, so that when a license was installed, a record would be added to the Installations table, and later on when we wanted to see where all a particular license was installed or what licenses a single computer had, the table could be filtered by computer ID or license ID and all matching records could be displayed. When I tried that out though I'm having a heck of a time getting the correct items to display.

Just as a basic test i set up a new form and dragged the tables onto it from the Data Sources window using "Details" view for each of them, so that it set up the table adapters and binding sources and navigator for me. I got rid of the auto-added labels + textboxes on the form and added just a couple new textboxes, 1 linked to the licenseID and one to another row i had in that table for productkey...tested it and it moves through the records fine and the correct data shows up in each box to correspond with the other. now though I'd like to add another control to display each of the ComputerIDs that are linked to the particular license being displayed in the other controls via the foreign keys routing through the Installations table, but I'm not having much luck.

Bound ListBox Item Count Changed Event

Feb 22, 2011

I'm using a textbox to supply a filter for the datasouce which is bound to a listbox. It works (mostly) with a few exceptions, one being i was to restrict the height of the listbox to the number of entries (upto a maximum number), so a bit like a combobox (which in effect is what I'm writing). One of the problems is when the number of entries changes there does not seem to be an event raised, although the OnDrawItem is called for the items to be displayed (the displayed ones!) Is there anyway to find out (in a derived listbox) when the number of entries has changed in the datasource?

Data Display - Using Tab Controls With Textboxes For Each Item

Oct 29, 2011

I am building an inventory program. One of my forms shows the store info. It will also have a section that shows all the equipment we keep track of at that store. I am currently trying to set it up by using tab controls with textboxes for each item. The code seems ugly and sloppy and I just don't like the interface. I am looking for ideas on a better way to do this. I know I could use a datagridview, but there is lots of data and I don't think there would be enough room for it.

Here is the code I have so far.
Private Sub GetTabData(ByVal StoreNumber As String)
Dim dt As New DataTable
'DSAlrm.Reset()
Dim DaAlrm As New SqlDataAdapter
Dim MyConnection As SqlConnection

VS 2008 : Data Bound List Box, Displaying Data Into Textbox?

Jan 3, 2011

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.

So this is what I got.

Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"

[code]....

It only adds the first rows details to the text box when I click the second record the first rows details are still there.

Display Data Below Specific XML Tag By Selecting From Listbox?

Oct 15, 2011

I just started learning VB.NET about a moth ago (I have been taking classes, so its been about 5 days worth of classes) and I decided to work on this project idea I had. Essentially, it's a database to keep track of anime and manga that I, or whoever else uses it, have watched/read.[code]...

However, now I want to make it so that when one selects a specific title in the list box, it will show the data in the tags below the <series> tag that matches the item selected in a label. One thing I just thought of is than since the list box gets populated in the order that the series are in, it could be easier to go in order from first item equaling the first <series> and so on.

VS 2008 : Display A Value From Data Table To A Listbox According To A Condition?

Jul 28, 2010

My aim is to choose a value from Listbox1 and on Listbox2 I would like to display the corresponding value from a table in my database. I mean, when I select Product A from Listbox1 (which is getting its values from row "Model" in my database table), I should see its price on Listbox2 which is available in the "Price" row of the same table (and also manipulate this price in different places for calculation etc.) . I am not sure if the best way is using "databinding.filter".

Here is the code I have but I cannot making it work:

Dim dtCOP As New AmetailorDataSet.COPDataTable
Dim adapterCOP As New AmetailorDataSetTableAdapters.COPTableAdapter
adapterCOP.Fill(dtCOP)

[code]...

A small note: my aim was using a Richtextbox instead of Listbox but I am told that Richtextbox is not suitable for using with datasources.
