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?

Data Bind A Drop Down List In A Gridview From A Database Table Using VB?

Dec 4, 2009

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>

Getting System.Data.DataRowView In Drop Down List As Opposed To Values From Database

Sep 30, 2010

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>

Finding Value In Drop Down List?

May 31, 2012

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.

Make Drop Down List?

Jan 13, 2010

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

.net - Drop-Down Image List In Winforms?

Aug 17, 2009

I'm trying to find a dropdown-style list for images I can use in a program of mine. It's fairly simple, just needs to display a few images in a grid with tooltips for each one, and I need to be able to get whichever one was last picked. For example,[URL] without the tab bar in it. Unfortunately my monetary budget is zero which means I can't purchase any controls?

Drop Down Combobox, A List Of Options Are Available?

Mar 12, 2012

Is using Public Property the best way to achieve the following.From a drop down combobox, a list of options are available. Each option in the combobox has a number of public properties that need to be associated with it.When a option is selected, the user will then have two buttons that each call a different sub, the appropriate options are passed to the sub.Each option will always have the same properties required to be passed.So I'm looking at something like this.

Public Class Parameters
Public Property server As String
Public Property replica As String
Public Propery path As String
End Class

Forms :: Drop-down List Combobox?

Mar 23, 2010

I 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.

Populating Drop Down List From Another Thread In ASP.NET?

Feb 22, 2009

I have multiple drop down lists on a page. They all contain list of countries. So in the background I am getting countries from database and caching them. I would like to populate those drop down lists from another thread. I am also using AJAX controls so I wanted that it all happens at the same time. And also after a user selects a country I want that towns from that country show to the user, and I want that getting towns happens also in another thread so that user can fill other controls while the list is not yet loaded.

I have read somewhere that I should give Page as a parameter to that thread and then find that drop down lists and populate them. But that is not working.

Here is a function that is called when another thread starts:

protected void GetCountries(object o)
{
if (Session["Countries"] == null)
{
