Is that possible? In other words, I want a dropdown list (and other list-type controls) which appears in edit more of a templated column to be populated with data at the run time. An attempt to do so results in non-existing object error. (Object reference not set to an instance of an object).

I've populated all the cells in a combo box column with values from 1 -
50 using the following code:
foreach (DataGridViewRow row in uxTabSummary.Rows)
{
DataGridViewComboBoxCell cell = (DataGridViewComboBoxCell)
row.Cells;
for (int i = 1; i < 51; i++)
{
cell.Items.Add(i);

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

I would like to have a combobox control that when clicked, displays a
DataGridView in-place of the normal dropdown list. I want it to be a
DataGridView with editing capabilities. The DataGridView would be bound
to a database. Microsoft Access has had this capability for years. I've
scrounged the Internet including the CodeProject but can't find any
free controls or source code. Does anyone know where I can find
something like this? If not,...

I have a Datagridview that is bound to a DataTable. So there are no
column templates to modify at design time.
Is there a way I can convert a certain column (if it exists) to a
ComboBoxColumn at runtime after the Datagridview is bound?

Let say "product A" only has "Suplier B", "Suplier D" and "Suplier E",
"Product B" only has "Suplier A", "Suplier C", and
"Product C" only has "Suplier B", "Suplier D".
I can provide store procedure for this, but I don't know how to put this different...

I have a data grid view which works very well in almost all respects. However, I have a problem that arises when I allow the addition of items to the grid on the fly. I do this by intercepting the OnEditingControlShowing handler and setting the DropDownStyle to ComobBoxStyle.DropDown:
protected override void OnEditingControlShowing(DataGridViewEditingControlShowingEventArgs e)
{
cb = e.Control as ComboBox;

There's an editable datagridview populated from a table say tblItems. Among the columns of the datagridview there's a combobox column named 'Category'. This column is populated by the respective 'Category' column of tblItems. Now in the 'Category' column of the datagridview I want to set the value of a certain cell to Null programmatically. Suppose when I press keyboard Delete button over the cell or some other button on the form, the value of...

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...

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,...
