The design of my website utilizes tables on every page that look almost
identical, save the data they are displaying. I have written the code
to create the body of these tables using a DataGrid, so I can
dynamically add rows to the table without modifying the HTML. Now, I
want to put this DataGrid into a user control that I can include in the
HTML code, then control the behavior of that DataGrid...

I have two questions about using the data grid and c#
If one of my columns returned in my dataset is null I want another
column to be used in the displayed column.
So this is what my datagrid looks like
<asp:datagrid id="datagrid1" runat="Server" allowpaging="true"
pagesize="25" autogeneratecolumns="False">
<asp:hyperlinkcolumn datanavigateUrlField="col3"
dataNavigateUrlFormatString="{0}" dataTextField="col1"

Hi, Where is a good place on the internet for me to learn about how to use
the datagrid. My grid's datasource is a dataset with one table from a DB. I
need to know how to perform Edit, Delete and insert for the grid. The books
I have are not that detail. I appreciate it someone can point me out to some
good reading/learning article.
Thanks,
Alpha

Although I've been using C# for the last month or so, and accepting out of
blind faith the ViewState, I do have some nagging questions about it... can
you help verify the following statements?
Application is across all sessions.
Session is across all pages.
ViewState is sort of like Session, but for only one page. <-- Correct
statement?
Session is stored between page requests, somewhere in mem or IIS files --

Hi all,
What is the best way to allow the administrator of the application to
select which columns are displayed in a Databound grid in an aspx form. I
was thinking of creating a form and display all possible columns with a
checkbox. The admin would check the checkboxes for each column they want to
display in the grid. My question is where should I save these settings ( in
XML or SQL Server?). Also when these settings are changed, how can...

I have a question about the datagrid.
I have a datagrid and I have set the datasource property to equal a dataset.
the datagrid fills up with the columns (prodno, description, price , siteID

how do I hide the columns price and userID so that my grid only displays ?

Hi. I have a question. I am developing an application and I have to choose
the most suitable control to show records from some database queries, with
freedom in customizing control layout and behavior, leaving data read-only.
Good examples might be: control showing message list in Microsoft Outlook
(or Outlook Express); download-in-progress (or upload-in-progress) control
in Emule client; every common XP-style window showing files and...

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,...
