将ProgressBar插入ListView中

先见ProgressBar插入ListView中去。

progressBar = new Progressbar();

Rectangle rect = item.SubItems[2].Bounds;

progressBar.Size = new Size(rect.Width, rect.Height);

progressBar.Top = rect.Top;

progressBar.Left = rect.Left;

并在ListView的ColumnWidthChanged事件中添加如下代码：

Rectangle rect = this.lstViewFiles.Items[0].SubItems[2].Bounds;

foreach (ProgressBar bar in this.lstViewFiles.Controls)

{

    bar.Width = rect.Width;

    bar.Left = rect.Left;

}

 

我们发现，当ListView出现滚动条时,Progressbar无法移动，我们得重新修改下ListView。

首先，创建一个名为ListViewExtensions的类，该类继承于ListView,类中包含一个ListView所在窗口类的引用,并在类中重写WndProc方法。

public class ListViewExtension : ListView

{

    /// <summary>

    /// Upload Form

    /// </summary>

    private UploadForm uploadForm;

    /// <summary>

    /// Cotr

    /// </summary>

    /// <param name="from">UploadForm</param>

    public ListViewExtension(UploadForm from)

    {

        uploadForm = from;

    }

    /// <summary>

    /// WndProc

    /// </summary>

    /// <param name="m">Message</param>

    protected override void WndProc(ref Message m)

    {

        base.WndProc(ref m);

        if (m.Msg == 0x0114 || m.Msg == 0x0115)

        {

            Rectangle rect = this.Items[0].SubItems[2].Bounds;

            this.BeginUpdate();

            //移动ProgressBar的位置

            foreach (ProgressBar bar in this.Controls)

            {

                bar.Left = rect.Left;

                bar.Width = rect.Width;

            }

            this.EndUpdate();

        }

    }

}

效果图如下：
