I have a combox column in a datagridview (vs2005 and VB.NET). Once I select
an item from the dropdownlist in the combox and do a save, I can no longer
remove the item. I can change my selection but not return to a no item
selected state (ie set its foreign key value in the table the row is bound
to null). I can hit Ctrl-0 and the text portion of the combobox dissapears
but on save it always comes back with a selected item in the list. How...

Hi,
Forgive me for posting this message in 2 groups -- it appears that the Data
Access group isn't very active, so I'm posting again here:
I have a DataTable that I want to fill using a DataGridView. I've set the
DataSource of the DataGridView to my DataTable. My problem is that I want
some of the columns to be drop downs. For example, the user will need to
enter a "product" into one of the columns. There is a list of "products" in...

I am having a problem with my datagridview. I have a small table that
has two columns. The first column is bound to my dataset. The second
column is a combobox. I add items to the combobox based on the
information that I get from a text file. I then try to set the value of
the combobox to a specific value based on the first column.
The code is working to set the value, but it will not refresh and
display the selected value on the screen...

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:
table JobTypes
1 | Manager
2 | Controller
3 | Supervisor
table Employee

New to databinding in vs2005, I always did it manually in 2003. I have no
problem loading comboboxes, and a change in that combobox changes the data in
the textboxes but I can not figure out a way to get the data in a
datagridview to change. For example 2 columns are ID and amount_paid, the
datagridview loads on form load with all ID's and amounts. How do I get it to
only bring back the selected ID. Sounds like I may need to change the SQL...

I have a datagridview control, and one column is a ComboboxColumn. I
simply create a ComboboxColumn, add items to it, then add the column
to the Datagridview control.
If I were working with a simple ComboBox, I could capture an event
that fired everytime the selected item changed. Is that possible if
the DatagridView control?
I've looked at various events, but none give me what I want. For
example, the CellEndEdit event won't fire...

I let the use modify the text of a combobox and then I replace the selected
item with the new text (in Keyup event).
But if he sets the Text property to an empty string ("") that sets the
SelectedIndex to -1.
Do you have any suggestion for getting around this problem?

Marc,
Thank you very much. I have issue on implementing add row properly using
this.
User presses down arrow in last row in grid starting adding new row.
Then user changes its mind desiding that new row should not added and
presses up arrow.
DataGridView does not show this unfinished row anymore.

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,...
