Multiple Combo Boxes Showing Data From The Same Data Source?
May 10, 2010
I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.

im trying to pick up Visual basic on my own with no friends/family that have any programming experience.. I'm struggling (surprise surprise)Heres what I'm trying to do...I have 1 combo box, It will list product names.. Lets say 15 of them.. (I know 15 i could just as easily specify them individually within VB.. but lets assume I NEED to read them from an excel file.(Excel 2003)
Part 1 :Really all i need to know for now, is how do I load an excel worksheet into VB so I can call data up from the cells / rows / columns..
Part 2 : How do I define Which Cells from Each row or column I want to populate into the combo box... Presuming for the "Product name" combobox I have placed each of the 15 product names in the excel file under Row 1, column A through Row 15 , Column A.I want to avoid this and just call the xls file into VB. (Excel will be installed on any computer running this application if that matters. )

I've done data binding to my Combos and it works fine but my data base has over 260 000 entries, so I can't let user to move trough it, one by one entry until finds a match.What I am looking for is that user select value from Combo Boxes and Text Boxes get filled in with a matching values from the same row.Auto Complete helps in selection but I still can't work it out how to get values to my text boxes.

I have a school project where i have a form that works as a class registration. There is cboGradeLevel and cboCourse and cboNumber. If cboGrade level is freshman i only want the numbers that start with 1 in cboName to be displayed, sophomore =2, junior =3, senior =3. Then i want cboCourse to work the same for the second number in cboNumber. english=1, history=2, math=3, science=4. So if freshman and history were selected i only want the numbers that start with 12- to be displayed. What can I use to make this happen?

is it possible to have a single report from two different tables? Because I have been reading articles that are saying that it is not possible and a subreport should be implemented? Can anyone clarify this for me?
I've been retrieving the fields that I need for my report with inner join sql statement and setting it as the data source of the report that I had created but it doesn't show up when the crystal report viewer is loaded. I had the correct syntax based on testing on what is retrieved by the statement, the only problem is how should it be shown in a single report.

I am very new to VB 2010 and SQL This is my first project.
Have multiple combo boxes that can use the same dataset.
The issue I have is that when I select data in one combo box the other combo box will change to what i selected fo rthe first box and visa-versa.
The only way I found around this is to create a new dataset for each combo box.

I'm working on a program that is interacting with a simple Access database. When the form loads there need to be multiple text boxes that are bound to the same table and field in the database, Inventory_Table.Quantity, to display the quantity of the inventory. From there, orders are read into the system adjusting the inventory as necessary.
I need to specify what row these are each supposed to be bound to, because right now it is binding them all to row 0, which makes sense but is not what I want. Is this possible? Heres the code I have to bind currently.
txtTopQuantity.DataBindings.Add(New Binding("Text", myDS, "Inventory_Table.QUANTITY"))
txtLegQuantity.DataBindings.Add(New Binding("Text", myDS, "Inventory_Table.QUANTITY"))
txtFastenerQuantity.DataBindings.Add(New Binding("Text", myDS, "Inventory_Table.QUANTITY"))
txtShortQuantity.DataBindings.Add(New Binding("Text", myDS, "Inventory_Table.QUANTITY"))
txtLongQuantity.DataBindings.Add(New Binding("Text", myDS, "Inventory_Table.QUANTITY"))
txtWheelQuantity.DataBindings.Add(New Binding("Text", myDS, "Inventory_Table.QUANTITY"))

I am importing data from an excel file, and it is stored in a dataset. The data is then filtered with a binding source, and that data is outputted into a datagridview. The filtered data in the datagridview contains data for 2 identification numbers. I want to graph each ID number in a chart on their own bar, in either a stacked bar graph, or a double bar graph.
I am having trouble assigning each series to an ID number: I have tried using multiple binding sources, but each seems to override the previous giving too much/too little data. I have tried using multiple datagridviews, however I cannot assign more than one datagridview as the datasource for the chart. The code I have pasted below outputs a double bar graph, however both bars graph the same ID number.
Private Sub dataButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dataButton.Click
Try
Dim cnRange As String = "provider=Microsoft.Jet.OLEDB.4.0; " & _
"data source='" & strFileName & "';" & _
"Extended Properties=""Excel 8.0; IMEX=1; HDR=No;"""
'moApp.Visible = True

First i am pretty new to coding and everything so yeah...I wish to make a distance and fuel calculator as my project. Included will be multiple combo boxes with different sets of information (The manufacturer of the vehicle, model of vehicle, the vehicles fuel use per 100Km, its transmission type, users choice of where they will depart from and arrive etc.) Is it possible to achieve this without using a lot of combo boxes? I've experimented using if statements for example:
if combobox1.selected item = "Holden" then
combobox2.visible = true (it's bad i know)
Then from this they would choose their model type in another combo box and then choose their transmission type etc..I don't want to use this because then it will mean i will have to do it for each and every combo box for each and every different set of data because making one 'visible = true' i will have to make the other 'visible = false' and this will cause problems when i start adding a lot onto it.

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

Ive got 10 comboboxes on my form, each of them have the same items. I'm trying to get so that if I pick something from the first combo box it doesnt show up in the list for the 2nd box, etc. Also, I didnt want to just remove the item, incase the user changes their selection in a previous combobox. [code] Rest of the comboboxes have that last piece of code, with the boxes and stuff changed to the correct ones.
