I have a WindowsForms.DataGrid that I am using to display
a datatable. The datagrid is composed of
TextBoxColumns. I would like to make the DataGrid have
the following behavior. When a user selects a row in the
datagrid that row is highlighted and selected regardless
of the column. I have accomplished this by overriding
the datagrids mouse down event and selecting the row.
However under some circumstances the text box control

Hi:
Using the WinForms DataGrid, I would like to have the entire row highlight
rather than just the cell that was last clicked. How do you do this?
Thanks,

Hi,
I'm looking for a nice way to format the cell of my datagrid according to
some predefined 'rules'. I found a lot on the site of George shepherd, but
it wasn't really what I was looking for:
I found there: How can I change the font used in a Gridcell on a cell by
cell or row by row basis. Wih this code I am able to change the
Font/Background/... based on the position of the field (column and row). The
problem is: it only changes...

Can someone give a sample to prevent a row from being deleted in a
datatable?
I tried e.Row.RejectChanges(); in dt_RowDeleting() but seems does not work.
I need verify if there other data using data in this row before actually
remove it from datagrid.
I can certainly control with Delete button. But if I want to allow the user
to use Del key on the keyboard, I lost this kind control.

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:
