How i can move 2 user controls at same time ? I know move only 1 per 1... Any example or idea ?

To move 1:

C#

private void button1_MouseDown(object sender, MouseEventArgs e)
{
    btnStandard = (Button)sender;


        if (!this.dragInProgress)
        {
            this.dragInProgress = true;
            this.MouseDownX = e.X;
            this.MouseDownY = e.Y;
        }
        return;

}

private void button1_MouseMove(object sender, MouseEventArgs e)
{
    if (dragInProgress)
    {
        Point temp = new Point();
        temp.X = this.btnStandard.Location.X + (e.X - MouseDownX);
        temp.Y = this.btnStandard.Location.Y + (e.Y - MouseDownY);

        this.btnStandard.Location = temp;
    }
}

private void button1_MouseUp(object sender, MouseEventArgs e)
{
    btnStandard = (Button)sender;

        if (e.Button == MouseButtons.Left)
        {
            this.dragInProgress = false;
        }
        return;

}

I upvoted this question because I think it's an inherently interesting programming challenge in WinForms. But, when I say "challenge," I don't mean so difficult you have to be a very advanced programmer to write the code that implements it ! I mean "challenge" in the sense that knowing how to solve a problem like this requires you to have some mastery of Events, and Controls.

Before I respond, I'd like to ask you a few questions that will help clarify for me what functionality you want to create:

1. are you looking to "entrain" any number of Controls so that moving any one of them moves all the others the same distance on X, and Y ?

2. or, are you looking to have one Control that can be moved, and then other Controls that "follow" the movement of the Control that can be moved, but that cannot be moved themselves ?

3. are you looking for making your Controls movable as your Application starts, and leaving them them movable; or, do you want the ability, for specific Controls, to "turn off" being movable at any point while the Application is running ?

4. Do you want the end-user, to be able to, at run-time, "turn off" other Controls moving in synch with the Control, but still leave the Control movable ?

5. finally: do you wish to have a solution that moves, in synch, Controls of several different Types, or, are all the Controls to be moved of the same Type; for example: all Panels.

good points - as I have seen sometimes in your answers - you often think beyond the single requirment. I like your approach and I don't like that your comment can't be upvoted ;-)

Thank you very much, Johannes ! That kind of feedback means a lot to me.

What kind of userControls do you have? Can you put this 2 userControls to one panel for example and move that panel instead?

Rieth L 23-Oct-13 11:33am

I have a panel that i insert two Custom Controls, panel.controls.add(customControl1); i can't move the panel...

BillWoodruff 23-Oct-13 11:40am

The code you showed here for moving a Button can be easily adapted to moving a Panel: is there a specific problem that you have found ?

Rieth L 23-Oct-13 11:41am

Yes, because if the panel moves it will move all controls on it, and i need to move only controls that i have selected.

BillWoodruff 23-Oct-13 11:46am

That's very interesting: are you saying that you want certain Controls "in" the Panel not to move when the Panel is moved ?

It may be helpful to distinguish between Controls that are "in" the Panel, because they have been added to the Panel's ControlCollection, and Controls that are "on" the Panel, meaning they may appear within the Panel at run-time, but are actually "in" some other Control (or a Form).

When you say "selected," do you mean selected at design-time by you, the programmer, or do you mean somehow selected by the person using your application (at run-time) ?

Rieth L 23-Oct-13 12:24pm

selected at run time... by a ctrl+click or something like it

Hi, I'm on GMT +7 here, and it's time for sleep, but I hope you'll respond to my questions. I'm having trouble imagining a Panel moving and Controls within it not moving: can you help me understand why you are making this design choice ?

Knowing what your application is doing ... the "bigger picture" ... would be helpful here.

Rieth L 23-Oct-13 12:36pm

The panel will not move, the controls will...

Well, it seems we are back at "square one." PLease answer the questions I asked in my first response. Unfortunately, I am not psychic :)
