I have a web form that has most of the UI designed. On this form, some of the
labels, textboxes, dropdowns, etc. will be added dynamically, depending on
what extra bits of data the user decides they want to see. The question I
have is when retrieving the dynamic fields for my form, should I get
everything in one grab (dynamic fields and data) or keep the form dataset
separate from the actual data dataset? Also, please excuse my ignorance, but
if I get this information in one trip to the server, is this a mix up of
presentation and data layers, or am I totally off base on what those terms
mean? Thanks in advance for any replies.

Mike,
There is no point in creating and adding controls programmaticall y until you
have gotten back the data that your business logic rules dictate what they
should be.
In other words, get the data that results from the user's choices first,
then build and populate the controls needed for it. And don't forget,
dynamically added controls must be re-created on each postback.
A word of caution: If you are at the point in the learning curve where you
need to ask this question (remembering of course that we all start out "in
diapers") then the business of all this dynamic labels, textboxes, dropdowns,
etc. may prove somewhat daunting.
If you can, it may be better to design a page with all of the controls that
may be needed and simply turn on or off their visibilty according to the
logic requirements.

I have a form, that consists of 3 pages of fields. I'd like to create

variables, until the end, when the user submits. I can't figure out
one thing: I have dynamic form elements (dropdowns), that I'd like to

I have designed a form that has 5 different list boxes where the

do not necessarily need to have a selection made to be used in the

In essence the form can have selections made in all or none of its list
boxes to form the dynamic query

Hello,
Well, after an initial review of my database by my client, they have
completely changed their minds about how they want their form. As a
result, I'm having to re-think the whole process.
My Current Form (6 tabs):
- Owner, Property, Title, Docs, Queries, & Reports
- User is able to see (while navigating through the tabs) above in the
form : Owner Name, Address, Parcel, and SSN

Hi all.
I'm learning VB.Net and am developing a WinForms app.
I'm trying to make an app that I will use to scan in one or more than
on image. I want to use a tabbed interface to hold each image. Here's
the code I'm using for testing purposes. I've got the code in the
form's load event, but I think I'd have the same problems no matter
where the code existed. Right now, the form has an empty tab control,
everthing else is dynamic.

Hi Everyone,
Does anyone know where I can get my hands on a sample with source code of a
simple dynamic button control in C# Windows form. I am looking for a sample
that uses a class library that sets the properties send/passed from the main
windows form. I'm having problems with the class library, the button control
collection and my referencing it ie this.Control.Add(aControl);.
Any and all help is appreciated. Thanks in advance.

I am trying to use some dynamic controls that are built and then added
to tables. The problem that I am having is the timing of when I can
populate the controls and have the state remain after a postback. The
main question would be this:
Why does this work for maintaining state after a postback for dynamic
controls:
myText = new Label();
myText.ID = "myText";

I got a tough question:
The backgroud for this question is:
I want to design an application works like a engine.
After release, we can still customize a form by adding a button, and source
code for the button. (This is done by the form itself, not by using VS.Net)
(button and source code should be a record in database, these information
should be retrieve from database when the form shows up)
What I want is:

Hi
I'm trying to produce a report based on a dynamic crosstab. Ultimately
i'd like the report to actually become a sub report within a student

what grades the student has achieved in a list of different subjects
and the reason I need it to be dynamic is that students take different
subjects.
Basically I've been trying to doctor the KB article on dynamic

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
