Apr 5, 2011Is 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

Finding Value In Drop Down List?
May 31, 2012I 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, 2010I'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, 2009I'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?

View 1 RepliesDrop Down Combobox, A List Of Options Are Available?
Mar 12, 2012Is 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.

View 2 RepliesForms :: Drop-down List Combobox?
Mar 23, 2010I 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, 2009I 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)

Jul 7, 2011I have a couple of dropdown lists like this
<asp:DropDownList runat="server" OnSelectedIndexChanged="Update_ddls" AutoPostBack="true" ID="ddl1" />
<asp:DropDownList runat="server" ID="ddl2" />
[Code]...
I also have a function called Update_ddls which runs OnSelectedIndexChanged that looks like this
ddl2.Items.Remove(ddl2.Items.FindByValue(ddl1.SelectedValue.ToString()))
Which removes the selected item in ddl1 from the second dropdown but if I keep changing the ddl1 item then ddl2 won't have any items left in it.
Is there a way to re-add the previously deleted items in the Update_dlls function without re-databinding because if I re-databind I lose the selected item in the ddl?

View 2 RepliesC# - Code Up A Month And Year Drop Down List For ASP.NET?
May 1, 2009I have an internal application that I needs to have a drop down list for two date type elements: Month and Year.These values are not in a database or other repository of information.I know I could just setup a list with the values I need by adding them to a dictionary like object (I need to correlate the Month to the numerical representation, January => 01):
var months = new Dictionary<String,String>();
months.Add("01", "January");
...
The drop down list for the year will be a bit easier as I can just choose a starting year and iterate up to the current or current+1 year in a generic list.Is there a better way to handle these data elements? Something built in, or a good design pattern that I should be implementing?
