我在c# winform中有一个代码实现。输入框是ToolStripTextBox，显示在最上面一行。进度栏ToolStripProgressBar在ToolStripTextBox下面。进度栏ToolStripLabel的进度在ToolStripProgressBar下面。
DoubleBufferListView显示在ToolStripLabel下方。
但是，在显示ToolStripProgressBar和ToolStripLabel时，它们的位置仍然显示DoubleBufferListView的第一项。
代码如下：

using CommonTools;
    using System.Drawing;
    using System.Windows.Forms;

    namespace EWPEditor.Plugin.UI
    {
    partial class MainPane
    {
        /// \
        /// Required designer variable.
        /// \
        private System.ComponentModel.IContainer components = null;

        ///  
        /// Clean up any resources being used.
        /// 

        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
    
        #region Component Designer generated code
    
        ///  
        /// Required method for Designer support - do not modify 
        /// the contents of this method with the code editor.
        /// 
        private void InitializeComponent()

我试图通过复制你的设计器文件并删除事件处理程序来最小限度地重现你的问题。如果我禁用所有者绘制，事情似乎工作。根据你的帖子中提供的信息，这可能指向你的绘图代码中的问题（似乎没有显示）。
显示进度条和标签会导致列表视图移动。当发生这种情况时，它可能会像刷新列表视图一样简单，这样您就可以使用当前Graphics上下文绘制到新的边界。


的数据

public MainPane()
{
    InitializeComponent();
    listView1.OwnerDraw = false;

    toolStripProgressBar1.Visible = false;
    toolStripLabel1.Visible = false;
    listView1.BackColor = Color.Azure;
    listView1.View = View.Details;

    for (int i = 0; i < 5; i++)
    {
        ListViewItem item = new ListViewItem($"Hello {i + 1}");
        listView1.Items.Add(item);
    }
    listView1.Refresh();

    toolStripTextBox1.TextChanged += (sender, e) =>
    {
        toolStripProgressBar1.Visible = 
        toolStripLabel1.Visible = !string.IsNullOrWhiteSpace(toolStripTextBox1.Text);
        toolStripProgressBar1.Value = 50; 
        toolStripLabel1.Text = "Visible";

        BeginInvoke(()=>    
        {
        toolStripTextBox1.Focus();
        });
    };
}
