Hello
Now perhaps this is a bit dumb, but...
I just populated a new table via \copy. After that, I realize that perhaps is a good thing to have a row identifier in it, so I try
clapidus=> alter table tickets add column rid serial;
NOTICE: ALTER TABLE will create implicit sequence "tickets_rid_seq" for SERIAL column "tickets.rid"
ERROR: adding columns with defaults is not implemented

I have a DataGrid on a webform bound to a Datasource and can
successfully use <ItemTemplate> to create edit/update/cancel
functionality for user maintenance of data. I use separate logic to
delete a row. Everything works just fine.
BUT
I would like to add a button to (for example) the DataGrid header, which
when pressed will add a new row to the datagrid. This should then allow
the user to enter information into text boxes (in some...

Dear NG,
After being away from C# programming for a spell, I am trying my hand at
what should be a simple task. I have been hitting my head against the wall
this morning. I have a simple order entry application. The code below gets
line items from a SQL Server database and returns them to a datagrid by way
of a DataTable called lineTable. As long as I am just displaying columns in
the SQL database everything works well. I now want...

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 have a bound combobox the appears on a cell within the column of my bound
grid when the user clicks on a cell n(In my vb.net WinForm app).
I am trying to allow the adding of an item to that bound combo by allowing
the user to dynamically type in the new value directly in the combo box
whcih in turn updates the lookup table and then when they have finished
leaves that particular cell on the grid with the correct value.

Hello ng,
I have a datagrid that is bound to a datasource. That works good so far. Now
I want to add another column to my grid dynamically. That also works good
until the first postback. The column is still there but for some reason its
content is empty. I added the code underneath this post. The problem is that
the delegate CreateCellTemplate is not called anymore. But why? I can't
understand.. :-( Viewstate is enabled for the grid.

Hi,
I know this has been asked previously but I can't seem to find the correct solution to my problem.
I have a dataGridView that is bound to one of my database tables, as soon as the form loads, the grid is filled with data from the table, the user can add, edit and delete the records. My problem is that when the user adds a row, one of the columns should require a specific format (an input mask) such as : EV-10002-01, I want the empty...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
