I have an ASP.NET 2.0 page with two DropDownLists. I am using declarative
data binding wherever possible and trying to minimize the use of code. The
list of values in DropDownList DDL2 should be (filtered) dependent upon the
selection in DDL1. I think this inevitably needs some code, but I'd be happy
to be told otherwise!
I have some code to handle OnSelectedIndexChanged for DDL1 that sets the
FilterExpression associated with the...

I'm not sure if I'm going down the correct route...
I have a class which exposes a number of properties of an object (in this
case the object represents a customer). Can I then use this object to
databind to text boxes etc?
I can't use a dataset as the object has loads of derived logic, for example
updating one property may actually update several database fields for
example.

Essentially, InsertAT is broken!
For the past couple of hours, I've been getting this "Parameter name:
'-2147483550' is not a valid value for 'index'." error.
Apparently, its caused by having manually inserted a row in the table
bound to the Combo box. The InsertAt Method of adding a row just does
not work.
Hope this helps anyone with this problem.

I am using a detail view and binding it to a sql data source (at some
point in the future it will be an object data source).
I have seen the article "Working with Data is ASP.NET 2.0 ::
Customizing the Data Modification Interface", and its description of
how to turn one of the fields into a template field, then add a drop
down list. I want to do the same thing except I want two drop down
lists, with the second one populating its values...

I've come across an interesting bug.
I have workarounds but i'd like to know the root of the problem. I've
stripped it down into a short file and hope someone might have an idea about
what's going on.
It's a simple program that loads a control onto a form and binds "Foo"
against a combobox ("SelectedItem") for it's "Bar" property and a
datetimepicker ("Value") for it's "DateTime" property. The
DateTimePicker.Visible value is set to...

The process of verifying that an Object exists and that a specified Property or Method is valid is called Binding. There are two times when this verification process can take place: during compile time (Early Binding) or run time (Late Binding). When you declare an Object Variable as a specific Data Type, you are using Early Binding so the verification can take place during compile time. When you declare a Variable of the generic Object Data...

Hello all!
I found a solution to my original question, but there's still so much I don't understand about it, I thought I'd give this forum a try. At the very least, maybe it will help someone else who got stumped like I did.
It seems so simple... binding a DataGridView to a List<T>. These are the two general problems that I kept running into:
(1) When the data in the list updated, the data on the screen did not update.
(2) When I...

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,...
