Hello everyone,
I know this question has been asked many times in the forums, and after
spending a few days reading, I am still confused as to the answer.
I have a ListBox (lstBox), SqlConnection (sqlConnection),
SqlDataAdapter (daLookupData), SqlDataAdapter (daData), DataSet
(dsLookupData), and DataSet (dsData), all created via the IDE during
design-time. Here is the design of my simple tables: (An example

OK here's the scenario -
GridView - populated with Object DataSource - technically no problem there
(except what will be shown later in the post)
Edit/Delete - first column - 'JobTypeID' - in the Main Table, it just uses
the PK (int) from the JobTypes table - -
DropDownList - inside one column's EditTemplate of the GridView - populated
by another (db table) ObjectDataSource control. DataValueField=JobTypeID and
DataTextField=JobType

I want to use the selected value of a drop down list to filter a data source.
When i have done this before i have used a DataSourceControl and i have just
made the drop down a control parameter, which works well. However this time
i need to combine a set of results from two databases into a single data
source so i need to use ADO to do it. The problem i come up against is that
until the value in the drop ,down box is changed, the...

Forget about the controlParameter for the moment, for testing purposes i have
created the following
Markup:
<asp:Table ID="tblSelectRoute" runat="server" CssClass="asp-table">
<asp:TableRow>
<asp:TableCell CssClass="asp-table-header">Select
Route<asp:Label ID="lblTest" runat="server"></asp:Label>
</asp:TableCell>

I have a web page with a dropdownlist which uses a SqlDatasource and a
SelectCommand to show selections from a table. However, when I postback
(going into Edit mode) on a FormView I get the error "'ddlGroups' has a
SelectedValue which is invalid because it does not exist in the list of
items.
Parameter name: value"
I am changing the options in the page_load as follows:
Select Case txtGroup.Text

Hi,
i dynamically feed a dropdownlist which value from 1 to 20. That
dropdownlist is bound to field 'wa' (type nvarchar(4)) in 'mytable'. There
are 4 records and the values of field 'wa' are: 2 3 1 4. All those values
are contained in the list of items of the DD.
In normal mode, the field 'wa' appears for each record with the right value.
When i click on the Edit button, i get this error:
"DropDownList1' has a SelectedValue which is...

I am trying to trap the following error. I have tried to catch it on page
load and every event on the data source and dd. No luck.
I'm forcing the error by setting the dd.text to an invalid value on page
load which seems to be when the exception is thrown. How can I trap it?
Thanks.

I have a DropDownList in an ASP.NET web form that is populated with items
from a lookup table by binding that DropDownList to a SqlDataSource.
However, the items in the lookup table can change over time. The problem is
that when an item has been removed from the lookup table, and a user wants
to retrieve a record that used the deleted item, the following error occurs:
'ddlAssignedTo' has a SelectedValue which is invalid because it...

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,...

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....
