DB/Reporting :: Combobox - Get Data Based On The Selection

Jan 31, 2009

I have VS2005, Microsoft Access 2003

ComboA is binded to the Customerstbl and displays the CustomerNames. ComboB is Binded to the CustomerContactstbl for the selected customer above and displays all Contacts for that customer is a second cbobox.

I am having a hell of a time with this, When I select a customers name in ComboA, I want ComboB to automattically query the contacts in ComboB based on ComboA's selection. where do I create the query for getting the contacts for that customer?

In the Customer or Contacts tbl?

Is this something that would be better hard coding or is VS2005 that much improved that its ok to use these binding features?

DB/Reporting :: Dependent ComboBox Based On Selection In Major Category

Apr 3, 2009

I'm running into a little problem making one combo box dependent on the selection of another combo box. I'm using a access back-end to this project. I have two tables: MajorCategoryTbl and MinorCategoryTbl , MajorCategoryTbl has PK and description field, MinorCategoryTbl has a PK, MajorID (foreign key), and description field. I have two combo boxes on my form, one that displays the Major description, and one that displays the MinorCategoryTbl description, but the stored value is the PK for both. I want the selection of the minor category combobox to depend on what was selected in the major category combobox.

VS 2010 Populate Textbox With Excel Data Based On Combobox Selection?

Nov 29, 2011

Visual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.

What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.

Populating Textboxes Based On Combobox Selection?

Jan 8, 2010

I'm trying to populate textboxes on one form based on a selection on a combobox on another form. All data will be pulling from the same SQL table. I've got the combox to work fine to show the correct data in one of the textboxes by using the lines:

Dim connectionString As String = "Data Source=F03D3S-DEV01; Initial Catalog=dos_track;" _
& "Integrated Security=True"

[Code].....

,but not sure how to get the other textboxes to fill with the correct data (from the same SQL table row) associated with the combobox selection. I've spent SO MUCH time on this trying to figure it out, but am getting nowhere fast...

Grabbing Rows From A Dataset Based On Combobox Selection?

Jun 3, 2010

I am creating a program that will allow me to manage server EXE's for which I have the method to do so already completed. The problem comes when I want my front end to be able to use a database of different server configs stored in a dataset.

My Database has 4 columns (ServerID | ServerName | ServerPath | ServerMod)

I wish to be able to select the ServerName in a combo box (already done via Datasource/DataMember) and then load the ServerPATH and ServerMOD for that row into two variables.

Populate Textbox Based On ComboBox Selection Not Using Databinding

Apr 27, 2010

I have a form, frm1 w/a combobox, cboLocations, which is being populated using a sql string. There is also a frm2 w/a series of textboxes and other comboboxes. I want it so that once a selection is made from cboLocations, the textboxes and comboboxes on frm 2 are populated with the corresponding data. Here is what I have so far:

frm1:
Public Class frmLocations
Dim conn As New SqlConnection("Data Source=f03d3s-dev01; Initial Catalog=dos_track;User Id=vbuser; Password=tran3;")
Dim depot_refnbr As Integer
Private Sub frmLocation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
conn.Open()
[Code] .....

What's happening right now is that I make a selection from cboLocations on frm1 and click on the OK button, frm2 loads, but none of the textboxes are populating and one of the comboboxes, cboDepot, shows the different data when you click on the down arrow, but it's not displaying anything it its text field when frm2 loads.

I have a database with table "Customer" that will be the datasource for my form controls.

Dim cmdSelect As New OleDb.OleDbCommand

.net - Clean Way To Display/hide A Bunch Of Buttons Based On A ComboBox Selection?

Apr 14, 2010

I'm writing a standalone application in VB.NET using Visual Studio 2005. I want to display/hide a bunch of Buttons based on the selected value of a ComboBox. Each selection would have a different set of Buttons to display, and I'd like to have them arranged in a nice grid.

Driving a TabControl with the ComboBox value would be the kind of behavior I want, but I don't want it to look like a TabControl to the user because it might be confusing.Is there a way to do this?

Basically, I'd like Selection1 of the ComboBox to show Buttons 1-4, Selection2 to show Buttons 5-11, Selection3 to show (maybe) Buttons 1, 3, 5, 6, and 8, etc., have them arranged nicely, and have the GUI show only the ComboBox and the buttons.

Change List Of Combobox A Based On Item Chosen From Combobox B?

Jun 17, 2011

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.

For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

Selecting Data In One DataGridView Based On Selection In Another?

Oct 5, 2009

NB: I'm using Visual Basic.NET?My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid.When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid.So, basically, I want to dynamically display data in one grid based on user selection in another grid.My code looks like this so far...
