DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

Can you supply us with some code and information about how you move the controls?

With this code you can add panels and move them ONLY in THE Panel they are deployed.

//Limitation Code////::START::::

// Mouse Button Left Down
                 if (e.Button == System.Windows.Forms.MouseButtons.Left) // The panel is attached to the mouse and you can move it
                 {


                             //Selected Panel Limited location of Bottom and Right
                             if (this.activeControl.Location.X == Math.Min(Math.Max(activeControl.Right + (e.X - previousPosition.X), 0), activeControl.Parent.Width - activeControl.Width) && this.activeControl.Location.Y == Math.Min(Math.Max(activeControl.Bottom + (e.Y - previousPosition.Y), 0), activeControl.Parent.Height - activeControl.Height))
                             {

                                 int RightX = Math.Min(Math.Max(activeControl.Right + (e.X - previousPosition.X), 0), activeControl.Parent.Width - activeControl.Width);
                                 int BottomY = Math.Min(Math.Max(activeControl.Bottom + (e.Y - previousPosition.Y), 0), activeControl.Parent.Height - activeControl.Height);

                                 activeControl.Location = new Point(RightX, BottomY);

                                 ///!LocationRightPanel.Equals(this.activeControl) && this.activeControl.Bounds.IntersectsWith(LocationRightPanel.Bounds)

                             }


                             //Selected Panel Limited location of LEFT and TOP
                             else
                             {
                                 int LeftX = Math.Min(Math.Max(activeControl.Left + (e.X - previousPosition.X), 0), activeControl.Parent.Width - activeControl.Width);
                                 int TopY = Math.Min(Math.Max(activeControl.Top + (e.Y - previousPosition.Y), 0), activeControl.Parent.Height - activeControl.Height);

                                 activeControl.Location = new Point(LeftX, TopY);

                             }

Solution 1

To resolve this issue, please consider the panel left and top values for your piece of code,

May be the below solution is use full for you!

C#

if(panel1.Left < e.X)
            Control.Left = e.X;
            if(panel1.Top <e.Y)
            Control.Top = e.Y;

Here below i shown the code what i am using, But this one is suitable for only Left and Top side (Controls not moves outside of panel), This type not support for Right and Bottom Side, Both sides controls moves outside of panel. Please give me the coding for Right and Bottom position controls not move outside of panel.

if (e.Button == MouseButtons.Left)
{
if (pictureBox1.Left + (e.X - x) > 0)
pictureBox1.Left += (e.X - x);
if (pictureBox1.Top + (e.Y - y) > 0)
pictureBox1.Top += (e.Y - y);
}

We can't set right and bottom property values! These values are readonly so we always need to modify Top and Left properties only.

Hope the below approach is useful for you!

Take 2 panels and place them in bottom and right side of your panel.
set topBoundary and rightBoundary as per your requirement. I tried this approach is working fine.

C#

int topBoundary;
        int rightBoundary;
        private void Form1_Load(object sender, EventArgs e)
        {
            topBoundary = panel1.Bottom - 60;
            rightBoundary = panel1.Right - 100;
        }

        private void panel1_MouseMove(object sender, MouseEventArgs e)
        {
            checkBox1.Top = e.Y;
            checkBox1.Left = e.X;
        }

        private void panel2_MouseEnter(object sender, EventArgs e)
        {
            checkBox1.Top = topBoundary;
        }

        private void panel3_MouseEnter(object sender, EventArgs e)
        {
            checkBox1.Left = rightBoundary;
        }

Solution 4

Get your panel botton and panel right values in the run time and then adjust the boundaries.

Hope you got me!

Happy coding:)
