无法在面板中设置 PictureBox 位置

我创建了一个面板。这有 autoscroll = true

一开始我添加了 6 个带有图像的 256x256 图片框。我存储了最后一个图片框的位置，以便我知道在哪里放置新的图片框。

我还在面板的右上角添加了一个图片框（位置（8744,8744）），以便面板将拉伸到 9000px。

稍后，当我在面板中滚动时，我可以按下按钮并向面板添加图片框。问题是，当我设置图片框的位置并将其添加到面板时，它在视觉上完全错误。

添加更多图像的代码。

private void addPictureBox(Point pixelCoordinates, Bitmap image)
{
        PictureBox pNewImage = new PictureBox();
        imagePanel.Controls.Add(pNewImage);

        pNewImage.Image      = image;
        pNewImage.Name       = "image_:" + pixelCoordinates.X + "_" + pixelCoordinates.Y;
        pNewImage.Location   = pixelCoordinates;
        pNewImage.Size       = new System.Drawing.Size(256, 256);
        pNewImage.Visible    = true;
        pNewImage.BackColor  = Color.White;

        imagePanel.Update();

}

如果我调试并观察面板，它会说新的图片框具有我设置的位置，但从视觉上看，事实并非如此。

我注意到这就是真正发生的事情：图片框的位置是我滚动的位置+ location.X。

有人知道我该如何解决这个问题吗？

提前致谢。

I have a created a panel.
This has autoscroll = true

At the start i added 6 pictureboxes that are 256x256 with images.
I store the last picturebox location, so that i know where to put a new picturebox.

I also add a picturebox to the upper right of the panel(location(8744,8744)), so that the panel will stretch to 9000px.

Later on when i scroll around in the panel, i can push a button and add a picturebox to the panel. The problem is that when i set the location of the picturebox and add it to the panel, it comes out totally wrong, visually.

Code for adding more images.

private void addPictureBox(Point pixelCoordinates, Bitmap image)
{
        PictureBox pNewImage = new PictureBox();
        imagePanel.Controls.Add(pNewImage);

        pNewImage.Image      = image;
        pNewImage.Name       = "image_:" + pixelCoordinates.X + "_" + pixelCoordinates.Y;
        pNewImage.Location   = pixelCoordinates;
        pNewImage.Size       = new System.Drawing.Size(256, 256);
        pNewImage.Visible    = true;
        pNewImage.BackColor  = Color.White;

        imagePanel.Update();

}

If i debug and watches the panel, it says that the new picturebox has the location i set, but visually, it's not.

I have noticed that this is what really happens:
The location of the picturebox is from where i have scrolled + location.X.

Anyone got an idea how i can fix this?

Thanks in advance.
