在WinForm中,
双击DataGridView列头设置当前列的显示为指定的图片,
再双击时列头显示回之前的文字

public partial class Form1 : Form
    {
        bool flag = true;
        bool show = true;
        int index = 0;

        public Form1()
        {
            InitializeComponent();
            this.dataGridView1.Rows.Add("1", "1", "1", "1");
            this.dataGridView1.Rows.Add("1", "1", "1", "1");
            this.dataGridView1.Rows.Add("1", "1", "1", "1");
            this.dataGridView1.Rows.Add("1", "1", "1", "1");
            this.dataGridView1.Rows.Add("1", "1", "1", "1");
        }

        private void dataGridView1_ColumnHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
        {
            if (flag)
            {
                this.dataGridView1.Columns[e.ColumnIndex].Visible = false;
                DataGridViewImageColumn iconColumn = new DataGridViewImageColumn();
                iconColumn.Image = GetImage(Application.StartupPath + @"\g.png");
                iconColumn.Name = "new";
                iconColumn.HeaderText = "new";
                dataGridView1.Columns.Insert(e.ColumnIndex, iconColumn);
                index = e.ColumnIndex;
                flag = false;
            }
            else
            {
                this.dataGridView1.Columns[index].Visible = !show;
                this.dataGridView1.Columns[index + 1].Visible = show;
                show = !show;
            }
            
        }



        private Image GetImage(string path)
        {
            FileStream fs = new FileStream(path, System.IO.FileMode.Open);
            Image result = Image.FromStream(fs);
            fs.Close();
            return result;
        }

    }

好久木有写过代码了啊，将就将就看吧……

呃，上面没有考虑当前列问题，不过那应该不是什么大问题

不是整列显示指定图片,而是列标头显示就可以了.
比如是DataGridVeiwTextBoxColumn.双击它的列标头可以在列标头上显示指定的图片,再双击那图片去可以去掉
