Populate A Drop Down List With State Information From A Database?
Jun 7, 2011
Background - I'm trying to populate a drop down list with state information from a database. I'd like the full state name to be the option and the state abbreviation to be the value. Example:
<option value="AL">ALABAMA</option>
Current Progress - The full state names and abbreviations already exist in the DB. I've successfully populated the DDL with full state names from the DB. Here's the code I've used to do this (minus stuff I've deemed irrelevant).Model Context (generated from template):
Partial Public Class BrokerCRMEntities
Public Property States() As DbSet(Of State)
End Class
State Model (generated from template):
Partial Public Class State
[Code]...
Question - In addition to populating full state names like I've done above, I'd also like to populate the value of the select options in the same DDL with the state abbreviations in my DB/model. How is this done?

I am trying to initialize a dropdownlist in VB.NET but my dropdownlist is not populating any values. I want the DataTextField to be different from DataValues in the dropdownlist. Dropdownlist should display series of strings; DataValues should only be numbers.[code]...

I am trying to create a form to filter information from 3 different tables with 3 drop down lists.
Is there anyway i can select the information from 2 lists and ignore the 3rd?
FilterExpression="First_Name like '{0}%' and Award_Title like '{2}%' and CONVERT(Year, 'System.String') like '{1}'">
But I can only filter with the First name and Year - it seems to ignore the Award.

I have a few drop down lists that I'd like to populate from a table in an SQL database. I tried setting it in the DataBindings section of Properties but I guess that doesn't work.

So in this gridview, there is a column for status and I want to have a drop down list with Pass, Pending, Fail appear when the edit button is clicked. These values are already in a table, so I need to somehow bind from this table to each ddl for every row.Here is the column from the gridview. As you can see, I would like to just have a label showing when not in edit mode, and a ddl when the edit button is pressed
<asp:TemplateField HeaderText="During Production Status" SortExpression="DuringProductionStatus">
<EditItemTemplate>

I'm populating a custom dropdown list control on the fly that's tied to data grid using VB .NET 2008. The form will display all the manufactures when the edit button on the data grid is selected.
The dropdown I created works fine. However, when I try to populate the drop down with the respected manufacture values from the database, I only get a value of "System.Data.DataRowView" that being populated in the dropdown list as opposed to my values from the database.
Here's the basic code I use to first create and populate the drop down control:
<asp:DropDownList ID="Manufacturedd" Runat="server" DataSource='<%# m_ItrackerData.Tables("Misc_Manufacture") %>' SelectedIndex='<%# getSelectedManufacture(DataBinder.Eval(Container, "DataItem.Manufacture"))
%>'></asp:DropDownList>

i have a toolstripsplitbutton, and i want the drop down items to showhide when you click the button not just when the mini arrow is clicked so i call toolstripsplitbutton.ShowDrowDown on the event toolstripsplitbutton.click and to hide, i can call toolstripsplitbutton.HideDropDown but i can't seem to find any property that would indicate whether the toolstripsplitbutton is currently dropped down or hidden..i did not expect this to be this hard but i can't seem to find any indicator of whether or not the list is dropped down.

I am fairly new to VB (have done some VB in excell, but its a bit different)
I have a couple of questions:
1) How do I populate a dropdown list from a Database Row 2?
2) When I create a Database from Acess, where do I save the database? and If I build the exe program later on, will it include the database, or how does it work? I feel completely stupid, but one of the best ways to learn is to try over and over again

Is it possible to reorder the elements of a drop down list (combobox) via drag and drop?For example, when the list is dropped down, I want the user to be able to drag the items up or down to reorder them. I tried this (and some google searching) but I'm wondering if its just not possible:
Private Sub cmbClassLists_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles cmbClassLists.MouseDown
If cmbClassLists.DroppedDown And Not cmbClassLists.SelectedIndex = -1 Then

The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I have a form that has many controls. My next task is to populate the phone number (MaskedTextBox) and phone number type (ComboBox) when the cursor has lost focus from a ComboBox that has auto complete functionality. I have tried to do it and when the cursor leaves focus, the other controls are not populated. Nothing happens. I do not get any errors either. Screen shot attached for the form and I am also using a stored procedure to do this. There are two tables in question here. A client table that the name and phone number and then the second table that has the phone number type (cell, work, home, etc).There is an FK relationship between the two.
This is my stored procedure. It is called sp_GetClientInfoByName.
vb
CREATE PROCEDURE sp_GetClientInfoByName

how to change 2nd drop down list value after I selected the 1st drop down list value.
The best example is country and state. After user selected country, the state value should change accordingly.
I am still new in ASP.NET and I know in PHP it can be easily done using javascript.
May I know how to do it in ASP.NET using VB language?

I am trying to compare a calculated date with a value in a dropdown list. The value is a date.toString.This is what I have so far:
Dim sched = scheduleDateVal.toString("d"
If Holidays.Items.Contains(New ListItem(sched.ToString("d"))) Then
ScheduleDate.Text = scheduleDateVal.AddDays(1).toString("d")
End If
Holidays is a dropdown list bound to a database so that I can add a day to a scheduledate if it happens to fall on a holiday. This works if I add a string value to sched rather than converting scheduledateval to a string.

I'm creating a simulation programe. In one sheet I have a group of cells (AngleConf) that have a drop down list. I would like to make some operations when I change the value of one of these cells. It always works when I insert the new value manually. But it doesn't always works when I change it by selecting the value from the list. I supose that that happens because of some option that I change while I'm working but I can't find out witch one exactly.The code that I think that its implicated:
Sub Worksheet_Change(ByVal Target As Range)
If InRange(Target, Range("AngleConf")) Then
Call resistance 'Actualiser le r�sultat mecanique
