How to use splitter control in WinForms?

Using a splitter control in WinForm can be achieved by using the SplitContainer control. The SplitContainer control is a container control that allows users to adjust the size of two panels by dragging the splitter.

Here are the steps for using the SplitContainer control:

  1. Open or create a WinForm project in Visual Studio.
  2. Find the SplitContainer control in the toolbox and drag it onto the form.
  3. Drag and drop the controls that need to be separated (such as Panel, GroupBox, etc.) into the two panels of the SplitContainer control.
  4. You can adjust the style, direction, and initial position of the splitter bar by setting the properties of the SplitContainer.

Example code:

using System;
using System.Windows.Forms;

namespace SplitContainerExample
    public partial class Form1 : Form
        public Form1()
            // 设置SplitContainer的属性
            splitContainer1.Orientation = Orientation.Horizontal; // 水平方向
            splitContainer1.SplitterDistance = 200; // 设置初始位置

With the steps and example code provided above, you can now implement the use of a splitter control in WinForm.
