I have a databound combobox within a datagrid. I have set the DisplayMember
and ValueMember.
BUT, how do I capture the Value (SelectedValue) when the user changes the
selection?

I am using Visual C# .NET 2003 to make a ComboBox accept
both mouse and keyboard selection. For mouse selection
code, I double-clicked ComboBox to get the
default "comboBox1_SelectedIndexChanged" event. This code
(see below) by itself works as expected with a mouse. But
when using keyboard arrows to navigate the ComboBox drop-
down, the SelectedIndexChanged event is triggered which
is what I don't want using the keyboard. Instead, I want...

Hi, I have a comboBox set to also be editable. If I have code that is
something like:
cmbBox.Text = "Hello";
MessageBox.Show(cmbBox.Text);
The MessageBox will display just an empty string. I cannot figure this out.
The text "Hello" will be displayed in the combobox but it doesn't seem to
store the text. If I edit the box at runtime then it does store it correctly.

This is a repost of an item that I still cannot resolve.
I have 3 combo boxes. The first leads to the second to the third.
When I have selected a value in the second box, the third box shows the
available information based on the second combo box selection. But if I
change my mind and select a different item in the second box, after the
third box has been populated, the third box still retains the information
that was previously...

I recently noticed that my dev machine is not displaying things properly.
I'm adding items to a combobox that do not display on screen. I can see that
the list expands when I click dropdown but nothing displays in the list. If
I select something, the text box portion gets updated with the value from the
list.
I notice similiar behavior on a msgbox - no text displays.
I believe my machine was recently updated to framework 1.1 sp1.

I tried an implementation of overriding a ComboBox control. I am simply
trying to avoid it repainting, but I can't seem to get it to work. What am I
doing wrong?
Please help.
Thanks,

I need to enter null value from combobox to business object property.
My combobox datasource does not contain ValueMember with null value.
So I tried to create combobox which stores null to bound object when text is

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,...

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
