VS 2010 Populate Combobox Textbox From List
Jan 24, 2012
I have a form with a textbox that holds data relating to job priority. txtPriority.Text = "Low" or "High" I have an amend button on the form that when clicked displays a cmbPriority object with a list that has "Low" and "High" in the list. When I click the amend button I want to the cmbPriority.SelectedText to = whatever is in txtPriority.Text. The item in the field will always be in the list. I have my combo box set to cmbPriority.Dropdownliststyle = DropDownList.

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.

I have a form on which I want the user to be able to select a name from a list. The list needs to be populated from an table in my dataset. I'd like the user to begin typing and have an autocomplete append select type feature let them zero in on the person they want as they type. My question is, what type of control would work best for this?

I want to populate a Combo Box with a list of names and from that have the contact information (address, phone, email, ect..) populate a series of textboxes. The list is roughly 20 names, but it could grow to a hundred or more. Since the contact information changes periodically, I would like a very easy way to maintain it (Excel or Access).
Update: I am just trying to understand whether I should use Linq (have to learn it) or is there some other way this should be done.

Im using a combobox that bound to a DataSet. The Dataset retreives it's values from SQL.
I can retreive the values fine. However only displaying (1) Column. Which is fine.
Here's where it gets complicated for me. The dataset has 2 other columns that get filled. I need the resulting columns to be sent to text boxes when I select a value from the combobox.

I have an editable ComboBox with a validation on the Text property to make sure manually entered info is valid.EDIT: All I want to do is populate the .Text property with the ValueMember of a selection rather than the DisplayMember I also have the .Items populated with valid entries having the DisplayMember and ValueMember set.My DisplayMember is a caption along with the data, and the ValueMember is the data itself.So Items might be:
(DisplayMember, ValueMember)
"Foo - 1ab2" , "1ab2"
"Bar - 3cd4" , "3cd4"
I had a validation on the text which can also validate manual user input like "5ef6" The problem I'm having is that if the user selects an item from the combobox it populates the text field with the DisplayMember property (ex: "Foo - 1ab2") which will fail validation.I have tried to manually set the .Text property with the SelectedValue or the SelectedItem.Value on each of the three relevant combobox events to no avail.I would like that the .Text of the ComboBox get populated with the .ValueMember of the item when selected rather than the .DisplayMember
EDIT: I cannot validate by trying to extrapolate the value from the caption. I send the Text off to a service to be validated.
void FillMyCombo
{
KeyValuePair<string, string> listValue1 = new KeyValuePair<string, string>("Foo - 1ab2" , "1ab2")
KeyValuePair<string, string> listValue2 = new KeyValuePair<string, string>("Bar - 3cd4" , "3cd4")
[code].....
The user can manually enter something like "5ef6" which will pass validation.But when they select an item from the list, rather than manually entering it, the .Text property gets filled with the caption and not the value ... so it will contain "Foo - 1ab2" and that will fail validation. I cannot change the validation method to "infer" the value from the caption. I have no control over that service. All I'm after is the displayed value EDIT: Say a user selects "Foo - 1ab2" from the dropdown list, I want the text in the box to say "1ab2" EDIT: I have also tried to set the .Text property in code but I can't seem to make it work in any of the ComboBox events. how to programmaticly set the .Text property (and make it commit!) on a selection event they will also answer this question.

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.

The below code is a sample code that is supposed to display the months in a combobox.
Dim months() As String = _
{"Select a month...",
"January", "February", "March"}
[code]....
But what am I supposed to do with this code? I have created and named the combobox "cboExpirationMonth", but where do I put this code? I tried to put it as a click event of the combobox, but that doesn't work. I created a button and tried to put the code in the button's click event, but that still doesn't populate the combobox.

In this windows forms app, I have a form with six comboboxes. Two are parents, one with a single child and the other with three children. All of these work beautifully except for one of the children. The code for each one is identical, and I've verified the query against the database a dozen times. I even have another of the children that is in the very same block of code. One works beautifully, the other one refuses to populate any data. Below is the code for the one that doesn't work. I would tell you on what line the error occurs, but it doesn't throw any errors. Try catches show nothing, and I have VS 2010 set to throw all errors, but I get nothing, just an empty combo box where there should be a list of names.

on the form I use one combobox with Data Bound items, Data source, Display member & Value member. Besides this combobox I have textbox with multiline turned ON. My code should write values from specific table in Textbox when I sellect ID on the combobox. Actually this code works but not in a way I want Me.TextBox2.Text = ComboBox2.SelectedValue
I would like to populate texbox from other columns as well. For my app I need one texbox in which I can see five lines of data, Company name, Address line1 & Address line2 & Address line3 & Address line4 . It's important to get data from different columns and each column in a new line.

I am trying to make a simple program in vb that includes a combobox with a textbox on top and a list box. Basically, the user should be able to type somthing in the textbox, click a button which adds it to the combobox, then click another button which adds it to the listbox. I have all of this done fine, but i am running into some trouble and have some questions.
First, theres a textbox right ontop of my combo box. I would like the textbox text to display whatever value is selected in the combobox. right now its just always blank because the textbox is on top.
Next, if the item from the combobox is added to the listbox, you should not be able to delete it from the combo box. how would i achieve this?
Finally, i need to create a function named "is included" that searches the listbox to check if a certain value is included in the list box. This search just needs to return true or false. I have no idea where to start with this part or what i should do.

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?
