How do I make my Custom controls draggable and droppable on a grid let's say?

I want to drag a panel(custom control) and drop it somewhere on my screen, in the best case in a grid, for example how it's done in Visual Studio, you can grab the solution explorer let's say and drop it somewhere, but how exactly do I do that?

what you are looking for is available on this thread

in coculsion:

public partial class Form1 : Form {

  public Form1() {

    InitializeComponent();



    //drag n drop setup

    this.AllowDrop = true;

    this.DragEnter += new DragEventHandler(Form1_DragEnter);

    this.DragDrop += new DragEventHandler(Form1_DragDrop);

  }



  //hovering over form with file

  void Form1_DragEnter(object sender, DragEventArgs e) {

    if (e.Data.GetDataPresent(DataFormats.FileDrop)) e.Effect = DragDropEffects.Copy;

  }



  //relising file into the form

  void Form1_DragDrop(object sender, DragEventArgs e) {

    string files = (string)e.Data.GetData(DataFormats.FileDrop);

    foreach (string file in files) Console.WriteLine(file);

  }

}

You need to build your project and then it will be automatically available in the Toolbox when you are in the XAML designer. Just like the common controls.

For Drag and Drop at runtime look and the official WPF documentation. Also I suggest you look at the GongSolutions.WPF.DragDrop library in GitHub it is open source so you can see how they implemented it if the functionality it provides does not do what you want.
