I've been reading all the help I can on the topic (MSDN, other) but I
can't make sense of this.
Desired behavior;
The user is to choose from the displayed list of the databound combobox
and the coresponding 'Id' from the lookup table is to be inserted into
the field of the new record.
I have two simple tables. "tblPerson" is the data table. The lookup

Dear group,
I'm currrently investigating a bug within a piece of our software whereby if
a DataGridView (bound directly to a DataTable) is ordered by column headers
(containing lookup combo boxes where the value is the foreign key of another
table), although the DataGridView is ok, the DataTable becomes out of sync.
In other words, I have a Grid of customers, and if a customer name column
header is clicked - the data moves in the...

I am looking for a resource to learn how to do multithreading in a data
bound app. So far, I have figured out that I can't update a databound object
on a worker thread, because that triggers a cross-thread call to the UI
control that it is bound to.
I have created a simple demo to explore the problem. The demo has a
dataGridView control, a bindingSource control, a backgroundWorker control
and a Go button. The grid is bound via the...

I'm changing from a DataGrid to a DataGridView and have run across a
problem. The items that are bound to the DataGrid have an int Property that
represents a primary key of a lookup table in my database. For example:

1 | Manager
2 | Controller
3 | Supervisor

I have a datagridview with 5 comboboxes. After selecting choices in the
first row, when the user move on to or enter into the combobox in the
next row, the selection from the previous row displays (as selected
value). The user assumes that as the selected value and may move on.
However once he leaves the combobox, the selectedindex is -1, and hence
nothing is selected.
I am still trying to figure out how can I set the selected value to -1,...

Hi all,
I've got a DataGridView bound to a DataTable, and I need to make
some of the columns into ComboBoxColumns. I've tried some of the
solutions listed here, but I can't seem to make them work. They might
not be the solutions I'm looking for; I just want to have a few
arbitrary values for a combo box and make sure everything in that row
is one of those values. My boss won't let me just leave them as text
boxes. How do I tell the...

Hi all,
I have to add comboboxes in the first row of datagridview for
mapping the database fields.
For e.g. I have to show Id, FirstName, LastName in each comboboxes in
the first row. if i select a database which contains 2 fields then
this data should be displayed from second row so that the user can
choose the header name for this two columns from comboboxes like Id,
FirstName, LastName etc.
Can anybody tell me the solution?

Hello
can anyone tell me if its possible to have mixed colum-types inside
one colum in a Datagridview under Net 2.0?
I need to have comboboxes (with different content), inputfields and
DateTimePicker inside one column depending on some flag on the
DataRow.
I am not using databinding.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...
