How would you add data source to your combobox from a combobox that is connected to the access atabase?they are both ın the same form of course and the software language ıs Visual Basic. I ve got two comboboxes that I need to connect with eachother combobox1 is showing the "itemsonsell" from the "table_items" table from my access database, the second one should show the "prices" value from "table_items" depending on which "itemsonsell" item is chosen on combobox1,I ve done the solution below,but it didnt seem to be working,it is showing all the "prices" that are under the "table_items" table's "prices" class.

I have an edit Contact Form that pulls data from access and loads it into textboxes and comboboxes. The text is working fine, but I am trying to pull a number from the ddatabase and display that value in a combobox that already has selections in it, so the user can edit it. For example the combo box is filled with 1,000,000 - 60,000,000 and if the number in the database is 2,000,000 I wan the combobox to display 2,000,000 Here is the

I am getting data from an SQL Server database and displaying the data on a Windows form.How do I navigate through the data in a Sequential Order or Sort Order using the the REP_ID number? Example: When I use the navigation to move from one data to the other, can I go from; example: 100001 to 100002 and so on?
Finally is there any hint as to why I am getting the time with the dates? I know it is converted to text but not sure how to remove the time and just get the dates.Here is the entire project code:

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

this is a subset of a previously posted problem, I have narrowed down my issue and am reposting a question from this thread: [URL] I have apparently confused the compiler by renaming some comboboxes in Visual Basic .net express? (See relevant code below) I think the confusion is in who should handle what, with two routines named with variations of ComboBox1 and one handling the other ( it confuses me just trying to interpret it mentally):

I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).

I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

I have tried to set up combo boxes in the gridview but all the combo boxes have the same value in them instead of the value from the database. I am using entity framework and WPF. There is a parent child relationship between two tables but the source for the combo box is a separate table with names and IDs for tags. I have been looking all day. Hopefully this won't be too easy to solve.
The "Tag" Column displays the combo box. The Column "Tag ID" displays the value from the database. When I display the data the TagID Changes in diffrent rows but the Tag column is the same (the first choice) in all the rows. When I change one combo box they all change. I can't see where they are hooked together.
Here is the XAML
<Window x:Class="MainWindow"

I am developing a Windows application in Visual Studio 2005, V2.0 using VB.NET. I am coding part of an Emergency Response Information System. On my form, I have two combo boxes (cboBaseStationID and cboPriority). I am trying to populate the datagrid with records from my database based on what is selected in both comboboxes.
For the first combobox, the user selects a name so the datagrid must only show records with that name. For the second combobox, this is a little more complicated. There are four emergency priorities in the combobox that the user can choose - 1, 2, 3, 4. In the database, there are different response teams (to be dispatched to these emergencies) and each response team has a grade of either 1, 2 or 3. [Code]

I have a DataSet with a DataTable that has several numeric columns of Data. The numeric data is composed of distances given in U.S. Standard units. I currently have my ComboBoxes set up and working, but I need to expand on what I currently have in two ways.I need to be able to convert the Decimal numbers in my data column being displayed to Fractions, is there a way to do this and maintain databinding? In this case its the Display Member of the data source...I need to be able to display my drop down options in different sets of units... I've written Unit Conversion classes to help take care of this, but I don't know if I can somehow do this as well and maintain databinding? I'd like to convert the units on the display members as well...
Private Sub ComboBox1_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles ComboBox1.SelectionChangeCommitted
Select Case ComboBox1.SelectedItem

What is the best approach for using ComboBoxes when dealing with issues such as displaying fractions and units...

I've run into a bit of a roadblock trying to figure out how to programmatically not allow the same data in multiple comboboxes. I'm usnig VS2008 and I have 3 comboboxes on a form, all with the same data, say "apple", "orange", and "red". The comboboxes are nothing more than a user definable sorting method on which gets calculated first. When I use the .SelectedItemChanged event on any of these, I'll obviously be duplicating. Any idea on how I can program to automatically switch the combobox that is duplicated to the value that is missing? I don't want to hard code it as further down the road I will have up to 7 comboboxes. Below is what I started with coding. Not sure if it is the best way to go about it, but it works on 4 of the 6 combinations.

I am having difficulty trying to fill two different comboboxes (cbo) with data from a database. More accurately, the 1st cbo gets filled correctly, but when I attempt to do something similar with the second, I'm getting an error about not being able to use the & Operator in my SQL string (Operator is not defined for string and DataRowView types). So evidently the SelectValue from my combobox isn't acting the way I expect.
The overall goal of what I am attempting to do is to fill two cbo's, one with a list of contracts and a second as a list of parts given the selected contract from the first cbo. There are 3 tables in the database that I am drawing the data from: the "contract" table, the "parts" table, and a bridge table called "partList" that has foreign keys pointing to the two other tables. The first cbo is a basic query to the "contract" table using "ContractName" as the display member and "idContract" as the value member. The 2nd cbo I would like to display the name of the part from the "parts" table but use the id of the part from the "partsList" table, and to further filter this list based on what contract was selected.
I am writing the code in VB.Net from VS 2010, storing the data in a MySQL DB, and using a DBFactory to create all the components from ".GetFactory(MySql.Data.MySqlClient)"Below is the code that has the two places I am attempting to fill the two cbo's. Also if there is a better way to handle this, please let me know.

I have a bit of a problem. I am using an Access database to hold data for my VB app. In the VB app, I have a data source thats pulling data from the database.
I modified the database today, deleted some tables, added another one, but the data source in the project window does not show these updated changes. I had to reconfigure the datasource with the wizard to get the changes to update.
Is there a way that i can get the data source to update itself when the form loads?
