Hi group,
I have a problem that I already have posted to the german C# newsgroup.
Since nobody could help me there, I'd like to try it here again:
I set the selected item of a combobox like this:
myCombo.SelectedItem = 3;
But after that the ComboBox displays only the first entry of the list.

When you use a bound combobox and you set its dropdown style to "dropdown"
that allows you to enter text in the edit box. But if you enter anything
other than a value in the current bound items collection, the .text property
does not update. Furthermore, you can't easily trap an event to examine the
new value if your program assigns it programmatically as opposed to someone
typing it in and tabbing away from it. That is, TextChanged does...

I have a DataBound ComboBox, which has a text value as the Value property,
and the UniqueID for that value is bound to the Combobox.Tag property.
When a user makes a new selection in the combobox, I need to run a SQL Query
with the UniqueID of the new value they are picking.
The .SelectedIndexChanged and .SelectedValueChanged events give me the .Tag
value BEFORE the new selection is made. I'm getting the value for the
previous value,...

I have a combobox that is populated with a list of names. When a name is
selected I want to populate a datagrid with name information. I have my
master-detail defined in my dataset and it works fine if I use a datagrid
for the master, instead of a combobox. But the combobox won't cause the
repopulation of the datagrid with the appropriate data. What's the trick?
TIA,

Hi-
I've seen this problem discussed a jillion times but I cannot seem to
implement any advice that makes it work. I am porting a large project from
VB6 to .NET. The issue is using the combo box bound to a table as a lookup,
drawing values from another table to populate the available selections. This
all worked fine in VB6.
I have distilled the problem down to a simple form drawing data from the
Northwind database for a representative...

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).

Hi,
I'm using vb.net express 2005 and I've got a project where I use a
datagridview with a combobox in the first column.
Depending on the value the user selects I have to set values of other
cells.
The problem is that I get the selected value when the datagridview
isn't in edit mode. First I have to select another cell.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

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,...
