Dear all,
Can any one explain(with sample code) how to create UI with controls at runtime using VB.Net. e.g. if user needs to add 2 labels & 1 textbox at a particular X,Y position(Based on Drag-drop) on the form he should be able to do it. Some other user want to add 5 labels at specific coordinate; he should be able to do it.

Thanks in advance..

Create the controls and set the location. What is the problem?

The usual problem is "MyControl.Parent = ..." or "myParentControl.Controls.Add(MyControl);"
Please see my answer: I provide and advice how to generate required "sample code".

There is too much code to do this and there is no magic code that will work everywhere. For sample code, please ask Mr. Google.

Sergey Alexandrovich Kryukov 30-Jul-13 12:59pm

Not really. Please see my answer — this is all one needs. Nothing to Google about.

You don't answer their question at all. They want the user to be able to drag and drop controls.

Manfred Rudolf Bihy 30-Jul-13 14:01pm

Well that depends. Doing the the drag and drop is just one aspect of creating the controls. The real work lies in how to incorporate the controls into the form so that they behave like they should. I do agree though that SA should have kept with his usual response that the solution to OP's question is either just to broad for Q&A or incorrect. (@SA: I hope you'll forgive me my little jab at your usual responses to this kind of question.)

Cheers!

Sure, Manfred. I actually appreciate criticism, as this is one of the main things in all kinds of activity, especially creative.

Well, yes, drag-n-drop is a separate issue, but the basics are the same...

The sample code already lies under your fingers, you just need to spot it.

I'll better explain you a pretty productive method of finding out all required techniques.

To start with, you should understand that there is no creation of controls "not in runtime", or during design time. No matter what you do, the control are always created during runtime. And of course, you need to learn what really happens, instead of using just the designer without understanding the essence of things. The designer is merely a visual tool used to generate some code which is actually executed during runtime. (And you should use the designer with care; overusing it is a usual problem leading to a lot of repetitive manual work without proper reuse and supportability.)

That said, here is what you can do: create the controls and their layout the way you want using the designer. When you are done, you will see some auto-generated code; it will be placed as a child node of the form node. Open the generated code and learn how to right the same thing. That would be the same very "sample code" you requested in your question. That's all.
