How to control docking order in WinForms

问题

As the title states, I'm looking for a way to control the order in which the items dock to the top of my control.

I've played with the windows form designer, and i cant seem to find what the RightClick->Order->SendToFront is doing, because thats exactly what I want to happen. As far as I can get to happen, as I add my contents to my control, the newest contents is always at the top, and I'd like for the Newer contents to be on the bottom, and the oldest contents to be at the top.

Summary: Is there an easy way in WinForms (C#), to control the order in which things dock to the sides of controls?

Edit: I have to do this from the code behind as i add my controls, I can't use any features of the WinForm's designer, but what I am trying to do, is mimic the WinForms Designer SendToBack and SendToFront features

回答1:

Use these methods:

myControl.SendToBack();
myControl.BringToFront();

回答2:

Go to View → Other windows → document outline.

In that window drag the controls so the docking is as you like it to be.

回答3:

As you said, the newest control added to the controls collection is the one on top. If you need a newer control to be added at the bottom, I'll suggest to create a list of controls, add the controls to the list, reverse the list and add the list to the controls collection.

List<Control> controls = new List<Control();
controls.Add(new myFirstControl());
controls.Add(new mySecondControl());
controls.Reverse();
this.Controls.AddRange(controls.ToArray());

回答4:

A control has two methods to achieve what you are looking for: BringToFront and SendToBack.

回答5:

The order in which the controls are being added to the Controls collection determines the docking order.

回答6:

(For the sake matter of showing another option): In Visual Studio 2012 (and later):

Select the Control you want to Move to the Front (or back);
Click in the below marked buttons (Bring to Front / Send to Back);

This will give you the possibility to rearrange the Controls to your desired order.

回答7:

Note that when doing this programmatically, then there's a very easy way to achieve this, namely:

containerPanel.Controls.SetChildIndex(Element, 0); //sends element to the bottom of the list

回答8:

Use the FlowLayoutPanel it does exactly what you want.
