I have a datagrid containing a drop-down-list. The datagrid contains
Edit,Update,Cancel buttons and respective events. Whenever I make a change
to one particular field (a drop-down-list in column3), as soon as I click
UPDATE the original value which existed at load-time replaces the value I
chose. Is this a postback problem, and if so how would I resolve this?
Thanks.

I'm new to this postback stuff and this should be a simple question:
I have a datagrid control on a page and have coded the ItemCommand on
the datagrid control to process a function that puts the selected index
of the datagrid into a hidden control (can't find any other way of
storing the index selected and retrieve it on postback). The value in
the hidden control doesn't change and I can't seem to find where the
selectedindex is on...

I created a custom DataGridColumn based on Marcie Robillard's MSDN
Article:
Creating Custom Columns for the ASP.NET Datagrid
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspp/html/creatingcustomcolumns.asp
The problem I am having is that the data in the custom datagridcolumn
is not saved to viewstate and after postback, the column does not
contain data.

Hello
I am currently in the process of creating a web page to display and edit reporting data. It consists of a few label
with instructions, a Drop-Down-List and Button (Load) to select a report to display, when the user selects a report and clicks the load button it will perform a postback and populate a datagrid on that page. The datagrid also exposes an edit button that they can click, which fires the EditCommand function and allows them...

Hello,
Hope somebody can help me with this cause I'm a ASP.NET beginner. I've
created A DataGrid, and I added few BoundedColumns, and in my
Page_Load section I added few TemplateColumns through the
myGrid.Columns.Add(myTemplateColumn). After that I bind the datasource
to the datagrid in the Page_Load only if it is not a postback.
Initially it works fine, but on PostBack (whatever I do on the
webform) my TemplateColumns dissapear :( Only...

I'm new to ASP.NET and I'm not use to the way things are handled with
this technology. I've been told that when I have a control, I should
only bind the data to it once, and not on each post back (basically
have the data binding done in the If NOT IsPostBack Then statement).
How come? How does this information get preserved?
Which raises another question. Becuase I want to get away from the
spaghetti code approach, I would like to create...

In our multi-tier application, we have several ASP.NET user controls which
will update the same data source provided by middle tier logic.
In this particular scenario we have one user control displaying the contents

Hi guys,
I am converting a rather complicated database driven Web application from
classic ASP to ASP.NET 2.0 using VB 2005 as the programming language. The
original ASP application works quite well, so at times it is tempting just
to port parts of it over mostly as-is. In fact, one MSDN article I read
suggested using straight HTML wherever possible to make the app more
efficient and less resource demanding.
On one page there are 2...

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...
