I take it that the only way to add rows to a DataList control is through DataBind?
If not, how do I manually add rows to a DataList control? I have searched everywhere and can't find an example anywhere other than
through building a DataTable, and then doing a DataBind.
Thanks.

Trying to figure out the technique which should be used
to add rows to a datagrid. I am thinking that I would
want an "Add" button on the footer, but I am not quite
sure how to do that. Is that the best method? Do you
have a sample of how to do this?

I am programmatically building and populating a table and then making it the
data source for a dataGridView. I want to add a column to the dataGridView
which will be a DataGridViewComboBoxColumn. I wish to populate, by default,
all of the ComboBoxes with the same list of three choices.
How do I add the DataGridViewComboBoxColumn, and do I first populate one as
a template for the others?
I will appreciate any help.

I want to programmatically add a row to DataGridView (a datasource was
binded with it), but when I call the method DataGridView.Rows.Add, a
System.InvalidOperationException will be thrown and the error message is:
Rows cannot be programmatically added to the DataGridView's rows
collection when the control is data-bound.
But if I create a DataGridView without any datasource binded, the method
DataGridView.Rows.Add can work normally.

Hi,
I am new to the forms world and have a silly doubt.
I have form with a DataGridview and an "Add" button. When the user
clicks on the add button, one row gets added to the datagrid.
Now I want that when the user hits the "Add" button, then new row
should be added and all the previous rows should be disabled for
selection/editing.
How can I disable previous rows for selection/editing?

I have a DataGridView that has potentially several hundred rows
(possibly a thousand or two).
I'd like for each row to have the proper height to accomadate the text
in the row. I tried setting the AutoSizeRowMode to AllCells. This
worked great on small datasets, but the program hung for a long time on
larger datasets.
I changed it to DisplayedCells, but this has some quirks: All of the
initally displayed rows are the correct height (for...

Hello:
I am binding a DataGridView with a BindingList<T>, where T is a custom
business object that implements INotifyPropertyChanged.
When you bind a DataGridView to a DataTable, it has this cool little
feature - it will not call DataTable.Rows.Add until after you leave
the DataGridView row. This is cool because it lets your user edit the
record as much as needed to get it into a valid state before actually
adding it to the DataTable.

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,...
