For what concerns controls insertion... it's not possible as controls position depends on the order they are added to the form. If you have layout space, however, you can insert a control between two controls physically... you calculate ctrl1 and ctrl2 positions and dimensions and you set the location of the new one depending on this.

blocks|key|4612436|text|使用Winforms时，只有添加控件的顺序才能确定它们的停靠行为。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4612437|最后添加的控件将始终最接近停靠边框，即使用DockStyle.Top位于顶部。无论是BringToFront、SendToBack还是Tab键顺序都不会改变这一点。|offset|length|style|CODE|4612438|只需以相反的顺序添加您的控件，或者删除它们并重新添加它们。|4612439|entityMap^0|0|L|D|16|C|1J|A|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]|$D|P|E|Q|F|G]|$D|R|E|S|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|T|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|U|8|@]|9|@]|A|$]]]|K|$]]

When using Winforms only the sequence in which controls are added determines their docking behaviour. 

The last added control will always go nearest to the docking border, i.e. to the top with <code>DockStyle.Top</code>. 
Neither <code>BringToFront</code> nor <code>SendToBack</code> or Tab-order will change this.

Just add your controls in reverse order, or remove them and add them again.

blocks|key|4612465|text|这是我对此的解决方案。基本上，您将控件和容器放在一个列表中。然后你使用带到前面，正如前面提到的，几乎都是帖子。当然，这也提供了插入的可能性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4612466|++++Panel+control1+=+new+Panel()+{+Height+=+16,+Dock+=+DockStyle.Top,+BackColor+=+Color.Red};

Here's my solution to this. Basically you put the controls in a list as well as the container. Then you use Bring to Front as mentioned is pretty much all posts. This of course also gives you the posibility of insert.

<pre><code> Panel control1 = new Panel() { Height = 16, Dock = DockStyle.Top, BackColor = Color.Red};
 this.Controls.Add(control1);
 Panel control2 = new Panel() { Height = 16, Dock = DockStyle.Top, BackColor = Color.White };
 this.Controls.Add(control2);
 Panel control3 = new Panel() { Height = 16, Dock = DockStyle.Top, BackColor = Color.Black };
 this.Controls.Add(control3);
 Panel control4 = new Panel() { Height = 16, Dock = DockStyle.Top, BackColor = Color.Yellow };
 this.Controls.Add(control4);
 Panel control5 = new Panel() { Height = 16, Dock = DockStyle.Top, BackColor = Color.Blue };
 this.Controls.Add(control5);
 Panel control6 = new Panel() { Height = 16, Dock = DockStyle.Top, BackColor = Color.Green };
 this.Controls.Add(control6);
 PanelList.Clear();
 PanelList.Add(control1);
 PanelList.Add(control2);
 PanelList.Add(control3);
 PanelList.Add(control4);
 PanelList.Add(control5);
 PanelList.Add(control6);
 Panel control7 = new Panel() { Height = 16, Dock = DockStyle.Top, BackColor = Color.Pink };
 this.Controls.Add(control7);
 PanelList.Insert(3, control7);
 for (int i = 0; i &lt; PanelList.Count; i++)
 {
 PanelList[i].BringToFront();
 }
</code></pre>

blocks|key|1263306|text|我知道这很久了，但这到底是怎么回事。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1263307|您可以使用SetChildIndex方法来控制它，如下所示|1263308|var+someControl+=+new+UserControl();

I know this is years old but what the heck.

You can use the SetChildIndex method to control this as follows

<pre><code>var someControl = new UserControl();
someControl.Dock = DockStyle.Top;
MainForm.Controls.Add(someControl);
MainForm.Controls.SetChildIndex(someControl, 0);
</code></pre>

I am writing a UserControl which adds child controls programmatically. Currently I am adding new controls like so:

<pre><code>this.Controls.Add(new Control() { Height = 16, Dock = DockStyle.Top });
</code></pre>

The problem I am experiencing is that new controls are added above the existing controls, so where I want the controls to be ordered 1, 2, 3, 4, 5, 6 from top to bottom, it's ordering them as 6, 5, 4, 3, 2, 1 from top to bottom.

I want to know how I ensure a new control is added after all existing controls (in terms of display order).

And also, I want to know if I can insert a control between two other selected controls

I have tried setting the TabIndex but that didn't help!
