Populate Combobox Depending On Other?
Nov 15, 2011
I have achieve to populate my combobox from sql and from this combobox to populate a textbox but now I have to do something more complicated.I would like to populate a combobox from an other combobox choice. And what i mean is that I have a table with Streenames and Postcodes. What I want to do is fistly to choose the Streetname from the one combobox and the interface to appear the Postcodes to the second combobox. Secondly, the postcode combobox should appear more than one postcodes because it is probable that the same streetname maybe belongs to more than one region(postcode).

I need to pull from an access database to populate a combobox. Then from there I need to have a second combo box populated depending on the selection in the first box. My thought of an example would be a website that is setup for selecting car make, modle,year...can that be done in VB?

I have a small section of a windows form that allows users to select when a customer should be called (i.e. day of the week, time and inbound or outbound)When the form is loaded I will extract the information using a dataset and bind to form controls. I want to use a combo box for call stautus - inbound or outbound - however wish to give the user the choice at runtime.My thoughts are I would need to set a static list (so the user could choose) and set the default or displayed value to the info the dataset has extracted.This code to select the index doesnt work when I am comparing the dataset result to the "Outbound" string even though I am using the ToString method.
Private Sub TestTelesalesForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Telesales_DEV004016TableAdapter1.Fill(TelesalesDataset1.Telesales_DEV004016)
Me.comboCallStatus.Items.Add("Outbound")

I have two ComboBoxes
<ComboBox Name="cmbMake" DisplayMemberPath="MakeName" SelectedValuePath="MakeID"/>
<ComboBox Name="cmbModel" DisplayMemberPath="ModelName"/>
I use LINQ-to-Entities to populate the cmbGroup ComboBox
Dim db as myDataEntity
cmbGroup.ItemsSource = db.Makes
How do I populate my second ComboBox (cmbModels) based on the selection of the first ComboBox (cmbMake) using XAML so that whatever I select in the first ComboBox automatically filters the ItemsSource in the second ComboBox?

I want to choose a value dynamically from comboBox depending of the values selected previously in two comboBoxes.the code that loads the comboBoxes:
Private Sub LightClassComboBox_DropDown(ByVal sender As Object, ByVal e As System.EventArgs) Handles AreaClasificationComboBox.DropDown
TrafficDensityComboBox.DropDown,.....
[code]....
The problem is that in the last Sub in the If sentence gives an error of: Null Reference Exception, because the compiler thinks that in that event the data are not loaded, although the data are loaded when loadcomboBoxes sub is executed.

I've already found evidence of another having this problem. You can see this on this post by someone else:
http:groups.google...096b3fcaa?pli=1
The problem is that when one navigates the combobox via the keyboard, the combobox's information doesn't update. If you click a value with your mouse, though, everything works wonderfully. The link I've mentioned suggests changing the binding from the Text property to the SelectedItem property. I'm very deep into this project and it would be a bit of a nuisance to change the setup so as to allow it to be bound to the SelectedItem property.What I'm wondering is whether or not I can detect the user changing the selected entry in the combobox and tell VB that they "clicked" the value, if that makes any sense.

I currently have a form with two comboxes. The first cbo is being populated with a project number, which is being pulled from the first column of a spreadsheet. I now want the second cbo to read the first cbo and then find that project number on the spreadsheet; when it finds that project number, I then need it to copy data from the row the project number is on. I have converted to vb from vba. Below is the code I used in vba (which obviously does not work). I only need certain cells from the project row.
Dim proj_num, rng As Range
Dim data, i As Long, j As Long
With Sheet1

I can understand since .ini files are pretty outdated, but I'll explain. I have a combo box, and inside the combobox I want it to display the names in a section of the .ini file. So say my .ini file contains the following:
[SECTION1]
Name = Billy
Lastname = Bob
Inside the combobox I wan't it to display the items "Name ", and "Lastname " only, not the section or the values.

I am a beginner in VB.Net. I have a table tblName; which consist of columns 'Name' and 'ID'. I want to populate the comboBox, where displaymember = 'Name' and ValueMember = 'ID'. In short, when a user selects a 'Name', return value should be the 'ID'. I can do it using DataAdapter. Another way of doing is; using a Listbox in parralel with the comboBox, which will be hidden, to save the 'ID' .
