Panel in winform behaving wrongly

Question

3.00/5 (1 vote)

See more:

I am having a panel in winforms which loads panels in it during a method call. In the method call i have written following code:

C#

//to get number of panel present in main panel so that new panel position can be set
 int counT = panel1.Controls.Count;

 Panel p = new Panel();
 p.Location = new Point(3, 3 + (counT * 197));
 p.Size = new Size(280, 150);

 //To add panel to parent panel
 panel1.Controls.Add(p);

Every time I call the method it will load a panel in the main panel. Everything works fine if I didn't scroll bar. Once I scroll the Scroll bar to down and after that i call the method, the distance between panels increases.

As per logic written the distance between two panel should be 197 pixel along Y axis, but it is increasing by more.

I have set AutoScroll==true

Any help !!!

C#

private void AddPanel(Panel target)
{
    int nControls = target.Controls.Count;

    Panel p = new Panel
    {
        Margin = new Padding(3),
        Anchor = AnchorStyles.Left | AnchorStyles.Top,
        Location = new Point(0, (nControls * 152)),
        Size = new Size(280, 150),
        BackColor = Color.AliceBlue,
        BorderStyle = BorderStyle.Fixed3D
    };

    target.Controls.Add(p);
}

If you want the Panels flush, then set their Dock property; example:

C#

private void AddDockedPanel(Panel target)
{
    int nControls = target.Controls.Count;

    Panel p = new Panel
    {
        Dock = DockStyle.Top,
        Size = new Size(280, 150),
        BackColor = Color.AliceBlue,
        BorderStyle = BorderStyle.Fixed3D
    };

    // verify you are getting added Panels
    // in the vertical order you expect
    // TextBox tb = new TextBox();
    // tb.Text = nControls.ToString();
    // p.Controls.Add(tb);

    target.Controls.Add(p);

    // fix the z-order so last Panel added is at the bottom
    p.BringToFront();
}
