The. NET running interface allows you to drag controls at will.

Copy codeThe Code is as follows: using System. Windows. Forms;

Namespace WinFormsApp_DragControls

{
Public class DragControl

{

// Controls to be dragged

Private Control m_Control;

// X and y coordinates when the mouse is pressed

Private int m_X;

Private int m_Y;

Public DragControl (Control control)
{
M_Control = control;

M_Control.MouseDown + = new MouseEventHandler (control_MouseDown );

M_Control.MouseMove + = new MouseEventHandler (contro_MouseMove );

}

Private void control_MouseDown (object sender, MouseEventArgs e)
{

M_X = e. X;

M_Y = e. Y;

}
Private void contro_MouseMove (object sender, MouseEventArgs e)
{
If (e. Button = MouseButtons. Left)
{

Int x = e. X-m_X;

Int y = e. Y-m_Y;

This. m_Control.Left + = x;

This. m_Control.Top + = y;
}
}
}
}

Call:

DragControl obj1 = new DragControl (button1 );

It indicates that you can drag button1 at Will on the running interface.

In addition, you can further adjust the widget size, use GDI + to add a boundary foot point, save the widget location to xml, and then read (layout) and automatically layout N Control algorithms, for more information, please contact me ..
