C#

Hi good day to all, I'am using a panel that have scrollbar in vertical. I want to display a new value of scroll bar when i end scrolling and I use this code

        private void panel1_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.Type == ScrollEventType.EndScroll)
            {
                MessageBox.Show(e.NewValue.ToString());
            }

        }
but it does not work, but when i use a single vertical scroll bar and use it this code :
        
     private void hScrollBar1_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.Type == ScrollEventType.EndScroll)
            {
                MessageBox.Show(e.NewValue.ToString());
            }
        }
it will work, I thought i can use the same code but it fails, Is their any way to do that?

Thank you in advance

using(MemoryStream mstream = new MemoryStream(File.ReadAllBytes(filepath)))
{
    if (useDecryption)
    {
        mstream = decryptor(mstream);
        mstream.Position = 0;
    }
    
    if (useDecompression)
    {
        mstream = decompressor(mstream);
        mstream.Position = 0;
    }

    result = (T) dcs.ReadObject(mstream)   
}

MemoryStream mstream = new MemoryStream(File.ReadAllBytes(filepath));

if (useDecryption)
{
    mstream = decryptor(mstream);
    mstream.Position = 0;
}

if (useDecompression)
{
    mstream = decompressor(mstream);
    mstream.Position = 0;
}

result = (T) dcs.ReadObject(mstream);
