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.

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.
View 7 Repliesfollowing issue I'm having:
I have 2 tables: locations and depot:
Locations:
site_refnbr (primary key)
site_name
depot_refnbr(foreign key)
[Code]...
I need to populate cboDepot's text property with the depot_name, and not the depot_refnbr that corresponds with the Location selected on frm1 from cboLocations.Frm1 has a button, and I'm not sure if I'd have to code this in the button click event, the cboLocation_Selected IndexChanged event, or in frm2's load event.
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.

View 4 Replieshow to go about this? 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
[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 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?

View 3 RepliesI have created a drop-down list box that holds 8 numbers representing a month span (3, 6, 9, 12, 15, 18, 21, 25 months). In order to prevent users from typing just anything into the text box above the combo box, I changed it to a drop-down listbox. The other requirement that I was hoping to implement was for the user to be able to type a number, after which the selection would jump to the appropriate item (i.e. the user types in '1', and the selection jumps to 12). This partially works. It will jump to 12, for example, but immediately after the user types the '1', the Selected Index event changes. The user cannot scroll down or up after typing in a number.
View 6 RepliesWhat I would like to do is bind a combobox to my own object which is as follows:
Public Class Categories

(I have put breakpoints and I know this object has data.)So on my form how do I bind my combobox to this object? The code I have is below:

cboCategory.DataSource = bs
cboCategory.DisplayMember = "Description"
cboCategory.ValueMember = "CategoryID"
but it returns the following error: Cannot bind to the new display member. Parameter name: newDisplayMember

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:

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.
