My form uses a dataset containing two tables, a base table
(Contact) and a lookup table (Insurer). My combobox is
bound as follows:
DataSource = datasetContact
DisplayMember = Insurer.InsurerName
ValueMember = Insurer.InsurerId
DataBindings.SelectedValue = Contact.InsurerId
It generally works fine. I am able to navigate records and

Is there any way to detect when an item has been added to the Items
collection of a combobox or listbox? I am inheriting a Combobox and want to
validate items before they are added to the combobox, but I can't find
anything that will let me do that.

I have a combobox that is very much like the one found in the RSS
project here:
http://msdn.microsoft.com/vstudio/express/visualCSharp/learning/
My projectNameComboBox basically is filled with a list of values from a
table, and as the user selects values, a datagrid displays related
records from another table because it is bound via FK relationship.
My table:

I am having an issue with graphical corruption upon re-selecting a
combobox which upon 'selected index change' event should list file
names in that folder in a separate combobox. Here is the code:
private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
IniFile INI = new IniFile(@"c:\\data\TM.ini");
string MisFileDir = INI.IniReadValue("Main", "MisFileDir");

Can I use a bound ComboBox for both browsing and editing?
I'm working on a small, standalone database application using Visual
C#.NET 2003 and an Access data file.
In order to keep the number of different screens down to a minimum,
I'm trying to use the same Windows Forms for both browsing and for
updating. This works fine for TextBoxes, but I'm running into
problems with my DropDownLists (ComboBoxes).

I'm using a ComboBox to display objects of a class I've defined, say CQQ.
Works great except somehow I occasionally set an Item to a String object
instead of an object of type CQQ.
It looks like Text replaces an item or something like that.
This results in a runtime error at which time I learn that the item that
should be CQQ is a String.

I've got a combobox where the SelectedValue property is bound to a class
property by a code like this:
MyComboBox.DataBindings.Add("SelectedValue", MyClass , "MyID");
My problem is that the MyClass.MyID property gets updated when the focus
leaves the combobox - not when you actually select a new item from the drdop
down list.
I would have expected this code to solve the problem, but it didn't:

I have a combobox whose rowsource is a union query. This query
displays a person's name in "lastname, firstname" format and in
"firstname lastname" format. The query results look like this:
Mouse, Mickey

When a person is added, the querys' underlying recordset is updated in
the NotInList event. I can't figure out how to refresh the combobox
to display the new person. I get the standard error message that the

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
