I have a (small) multi-table database application which allows
edits, print reports, and has two scrolling screen displays which
show information merged from multiple tables.
I'm having trouble with one of the scrolling displays which is
implemented as a DataGrid with several custom DataGridColumnStyles.
When the Form containing the DataGrid is made visible the initial
rows of the DataGrid's DataView source display as one might expect....

In a WinForms application with a DataGrid bound to a DataTable, if I
change the DefaultDataView.Sort property the order of the data in the
grid does not change.
If I change the Sort property then reassign the DataTable to the
DataGrid's DataSource the DataGrid does show the new order.
If I change the Sort property then call DataGrid.SetDataBinding the
DataGrid does _not_ show the new order.

I've been bothered for some time about my DataGrid not populating my rows
very quickly. I have about 10K rows loading into the grid.
I create a datatable dt with 2 columns, an ID and a display. The ID is a
member of the keys array.
I then create a DataView dv over the table, and sort it by Display and ID
column (in case of duplicate Display).
I then set my DataGrid.DataSource = dv;
I then load the datatable with my rows, and this is...

I just discovered that the datagrid does not display if the webform is in
new mode. Let's say, for instance, that my datagrid is for contacts related
to a company, so that companyid id a foreign key in the contact table.
Well, if the contact does not yet exist, the datagrid will not display.
I would like the datagrid to display the footer (which I've set up to insert
new rows into the datagrid), although perhaps disabled.
Is there a...

Hi,
I want to display a Label in a DataGrid according to some condition. I therefore check whether the condition is true in the ItemDateBound EventHandler of the DataGrid. Unfortunately the conversion is extremely costly in performance. Does anybody know how I could set the label (of the whole content of the TableCell) to .Visible = False without converting e.Item.Controls(2) to a System.Web.UI.WebControls.Label?

Hi,
I have 2 more questions :
1. Can I fill a datagrid by using a DataReader or does it have to be a
DataSet or a DataView?
2. In my datagrid I need to display two images and one of does images has te
be a link to a new page. How would you do that ?

I'm wondering if anyone has even encountered a control or other scripting
that will automatically rotate the rows of a datagrid... I am in the process
of building an asp.net application that will display statistics on a large
LCD display for viewing by people within the room (30 feet away). One
problem is that the screen can obviously only display so much legible data
at a time. I may have upwards of 60 or 70 rows to display on a rotating...

In my application, I want to populate all the directories & files
existing in a directory on the server in a DataGrid. To ensure that
all the directories get listed first followed by all the files, I am
appending all the directories with 0 & all the files with 1.
Moreover, each directory & file listed in the DataGrid will have a
corresponding CheckBox. To differentiate between directories & files,
I am adding the string "*D" (without the...

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
