           ((SimpleButton )a[counter]).Height =10;
           ((SimpleButton)a[counter ]).Width = 10;
           ((SimpleButton)a[counter]).Text = "mo";
           ((SimpleButton)a[counter]).Parent = pictureEdit1;
           ((SimpleButton)a[counter]).Location = new Point(10, 10);
             counter = +1;

Are you trying to drag and drop the DevExpress SimpleButton on the form ?

I'm not exactly sure what you are trying to achieve, but lookat your code fragment, I'm not sure you are either.

What you have done does not add a button to your form. It adds a SimpleButton (which I assume is a class you have defined) to an ArrayList, but not to your form.
It then sets a counter to one.

To add a button to your form at run time:

Button myButton = new Button();
myButton.Height =10;
myButton.Width = 10;
myButton.Text = "mo";
myButton.Location = new Point(10, 10); 
Controls.Add(myButton);

I assume that you also wanted to increment the count. If so then use one of these forms:

counter += 1;

counter = counter + 1;

counter++;

I would also not refer to "Parent" for a control, unless I really had to - it makes the control need to know about what contains it, rather than an object knowing about what it contains.

As for the rest "move this a[counter ] to any place with mouse click move on picture Parent" please try to give more info on what you are trying to achieve.

Here is one way to achieve the movement part:
User-driven applications[^].

When you have read and understood the article - the rest shouldn't be much of a problem.

I guess you are using DevExpress Property Grid Control[^] so this article should be of interest: Have a Great DesignTime Experience with a Powerful DesignSurface (Extended) Class[^] - not on the DevExpress components, but shows how something similar to the layout controls (the customize part) could be done using DesignSurface.

You could also use the DevExpress Layout Manager Controls for Windows Forms[^] - most, if not all, of what you need is included with the examples :)

Basically a good collection of links - and with a bit of reading you should be able to make a wonderful UI.

Good luck!
