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.

I have a IF statement which is checking each row in the data table (for a match) and ELSE statement with commands which are executed if the If statement is not satisfied. Now I would like to write like so that it goes to the Else part BUT ONLY for values which are not satisfied in the IF statement. If I am more specific; I would like to calculate values if a match is found and just print them if it is not fond (usually there are both cases). Now the problem is the bold text; if there is a match found I don't want it processed BUT if the match is found I do. How can I write that?

Is it possible to select an item in one listbox and then display the data of another listbox with the same indexed position? I am planning a project and this is something I would like to attempt but I haven't figured out how to do it.[code..]
I tried doing the above code but instead of displaying the listbox text the message box just returned false.

I have a listbox populated with peoples names. When I click on a persons name in the listbox, a datagrid will unhide itslef, connect to a DB, and list all of the pictures that person has. All the pictures are stored on a drive in a folder named after the person. i.e.
Greg Palinkas has 52 images stored in F:PicturesGregPalinkasImages.
I would like to display all of those pictures in a Table Layout Panel populated by the choice I made in the listbox, so if I select Greg Palinkas, the Data Grid is pupulated with the names of all the images i have, and the Table Layout Panel is populated with all the pictures I have in my GregPalinkasImages folder. I have got the Data Grid updating and running smoothly, but am lost as to how to get the images to come up.

I have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically. I do not want this because I want the listbox to select an item only when the user clicks on it. Otherwise, the iteme should ony be listed. Is there a way to manage this?

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...

I'm trying to set up a form that I can use to sort names. What I've done is set up a table with with the persons name and info in it as well as one field for a platoon number, and my form is basically 5 listboxes. I want unsorted names to appear in the first box, and sorted names to appear in their coresponding listbox (based on the platoon number in the table). I set up a query through the wizard (from the listbox itself) that will pull the info that I want, but so far it seems to pull it to all the listboxes rather than just the one I want.So far I've figured out how to make the listboxes fill on form load or on a button click (though in both cases all the listboxes are filled with the same data).Eventually I'd like to be able to sort these names in the various listboxes by dragging and dropping, but one thing at a time.So:1. Am I going about this from the right angle or am I making this needlessly complicated?2. How can I get this to sort the data to the correct listboxes on formload?

Was researching this but could only find how to use a datagrid which is displaying from a database? I currently have a for loop which goes through a 2d array and prints out all the things I want into a textbox but, what I want is to be able to have a table and print the things I want into rows and columns instead. I am new to VB.NET in Java it was just a matter of creating a table and a table model and loading the data through that way but not sure how to do it in .NET

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.
