VS 2008 Fill ListBox From Combo Selection
Apr 23, 2009
As the title suggests I have a ComboBox and 2 listBoxes on a form. I need to fill the left ListBox with items not now asssociated with the ComboBox selection and the ListBox on the right with items already associated with the ComboBox selection. Is it possible to populate the ComboBox and each ListBox using only one query and returning a dataset of ALL the data to do so, or do I need to Populate the ComboBox, then use 2 queries, one for each ListBox?

I've got some code like the following. I want it so that when I chose an item in 'select 1' it changes the in the second combo box but I'm not sure of the best way to go about it. Does it have to be AJax or can it be done with just Javascript?

I'm new to VB.NET and looking for some help with combo boxes. I was wondering if it is possible to link 2 combo boxes to each other based on user selection? [code]If the user selects Dept Name "Bakery" from the first combo box the second combo box should fill with the appropriate Section Name i.e. "Bread", "Cakes" etc.I am using VS2008 and the DB is SQL Server 2008. Both combo boxes are currently bound to the above Tables and displaying all Dept and Section Names.

ok, got a question here, two really. first i'll ask the hard one, as i think i have my other one out of the way so i'll save it for later but i made a program where a user enters in dimensions in several text boxes in inches. there are radio boxes that the user decides what thickness of wood they would like to use. what i'd like to do is add metric into the program and use two combo boxes. one combo box drops down and you can select inches, centimeters, or millimeters. the other one drops down to choose the thickness of the wood.ok now here's my question. say i pick inches in the first combo box, i'd like the second one to display only the thickness of the wood in inches, no metric. if i pick centimeters, i'd like the second combo box to display the thickness of the wood in only centimeters, no millimeters or inches. and the same goes for millimeters.i also have the program on a timer that runs at 100 milliseconds so the user can quickly see the differences in dimensions they put in instead of having to hit the calculate button over and over and over (not sure if that really matters or not, had a couple issues with the boxes earlier but don't think it was timer related now)but is this possible? basically just looking for the kinds of drop boxes that you see on a page like autotrader.com where you select dodge, and then only the dodge cars are listed, select chevy and the chevy cars are listed, etc.

I am currently stuck in one part of my application. I have two combo boxes that i am having the users select from. The first combo box is simply bound to a datatable. that is working properly. The second one i need to populate off another datatable after sorting out what the first one is requesting. Basically it's choosing a line number on the first box and then selecting the machine associated with that line number.[code]...

I am trying to fill a combo box from SQL Server 2008. Getting the Combo Box to populate isn't the problem. What I need to do is have the text field read the field value that goes with a specific id that I search by, while keeping all other fields available to chose from to change the value for that specific id and save back to the database. I know this isn't clear here is the best example I can think of:
COMBOBOX --FieldValue------->
--DropDownField1--> Ten
--DropDownField2--> Twenty
[Code].....
I seriously might have to infest in some Rogaine if I have to spend another ten minutes on this. I do know that I am missing an id to compare to but when I add the id into the sql statement the combo box only fills with the one value that it equals to without the option to chose from the several others to change.

I am still having issues with the combo box. I have the correct query. I have four tables in MS Access. I need to create a form in Visual Basic that has a combo box and a datagrid. The selection from the combo box will display all relevant information about that person on the datagrid. For example, if I select John Doe (from the combo box) the datagrid should display: [Code] How do I add John Doe to the combo box and link this query to it, when upon being selected, it displays the result in the datagrid?

I have a combo box on few of my vb.net 2010 programs. The end users that use my program have touch screens and they have a hard time making selections on the combo box. I have an Android cell phone and when ever there is a combo box it will open another screen and making the selection is a breeze.

I have the following query that executes when my form loads. It's the rowsource for my combo box. The query is fine and populates the combo perfect, however, when i click into the combo box I cannot click out of it or even close the form. I have tried taking out the line of code that fills the form via table adapter on load and it works fine (opening the form unbound by the main table). Has anyone run into this before? I have another combo box on the form setup the exact same way and this is not happening. I've experimented with different datatypes etc....
code to populate combo box:
Public Shared Function LoadCallSource() As String
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and Settingsdiw07My DocumentsDaily Backupsphone memo backend.mdb"
[code]....
If I take out the line
Me.MemoTableAdapter.Fill(Me.Table_Memo.Tables("Memo"), intMemoID)
The Combo boxes do not act up or "Lock"
