数据绑定图片框背景到列表索引？ [英] Data bind picturebox backcolor to list index?

问题描述

有人知道如何将图片框的背景颜色绑定到列表的某个索引吗？

Does anybody know how to bind a picturebox's backcolor to a certain index of a list?

我现在已经尝试了两天而且正在拉我的发单。

I have been trying for two days now and am at the point of pulling my hair out.

public override void Refresh()
        {
            base.Refresh();

            Controls.Clear();
            items.Clear();
            if (palette != null && palette.Color.Count > 0)
            {
                for (int i = 0; i < palette.Color.Count; i++)
                {
                    int x = i % columns;
                    int y = i / columns;

                    PictureBox pictureBox = new PictureBox();
                    pictureBox.Location = new Point(x * 16, y * 16);
                    pictureBox.Size = new Size(16, 16);
                    pictureBox.BackColor = palette.Color[i];
                    pictureBox.Parent = this;
                    pictureBox.DataBindings.Add("BackColor", Palette.Color[i], "", true, DataSourceUpdateMode.OnPropertyChanged);
                    //pictureBox.BindingContext[palette.Color].Position = i; <-- throws null object exception
                    pictureBox.Enabled = false;
                    items.Add(pictureBox);

                }
                Size = new Size(columns*16, rows*16);
            }
        }

调色板是一个持有颜色列表，最多16个。

palette is a class that hold a list of colors, up to 16 currently.

和项目只是一个跟踪我的图片框的列表。

and items are just a list for keeping track of my pictureboxes.

您好Shadowblitz16，

Hi Shadowblitz16,

我认为您使用该列表来存储pictureBox的BackColor，  ;如果是，请更改代码：

I think you use the list to store the pictureBox's BackColor, if so, please change the code:

items.Add(pictureBox);

收件人：

items.Add(pictureBox.BackColor);

如果我误解了您的问题，请告诉我并提供更多代码，以便我可以对其进行测试。

If I misunderstand your question, please let me know and provide more code so that I can test it.

希望有所帮助！

最诚挚的问候，

Stanly
