DataGridView 实现一列单元格 显示多操作方式

RT：

主要使用的方法：

        在CellPainting绘制操作方式

                                  

        private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)        {            if (e.ColumnIndex >= 0 && e.RowIndex >= 0)            {                if (this.dataGridView1.Columns[e.ColumnIndex].HeaderText == "Op")                {                    Employee model = this.dataGridView1.Rows[e.RowIndex].DataBoundItem as Employee;                    if (model != null)                    {                        StringFormat sf = StringFormat.GenericDefault.Clone() as StringFormat;                        sf.FormatFlags = StringFormatFlags.DisplayFormatControl;                        sf.Alignment = StringAlignment.Center;                        sf.LineAlignment = StringAlignment.Center;                        sf.Trimming = StringTrimming.EllipsisCharacter;                        e.PaintBackground(e.CellBounds, false);                        int md = model.Age % 3;                        string text = "删除";                        if (model.Age % 3 == 1)                        {                            text = "修改";                        }                        switch (md)                        {                            case 1:                                e.Graphics.DrawString(text, this.dataGridView1.Font, Brushes.Red, e.CellBounds, sf);                                break;                            case 2:                                 string text2 = "删除";                                if (model.Age % 3 == 2)                                {                                    text2 = "修改";                                }                                SizeF size = e.Graphics.MeasureString(text, this.dataGridView1.Font);                                SizeF size2 = e.Graphics.MeasureString(text2, this.dataGridView1.Font);                                float z = size.Width / (size.Width + size2.Width);                                float z2 = size2.Width / (size.Width + size2.Width);                                RectangleF rect1 = new RectangleF(e.CellBounds.Left, e.CellBounds.Top, e.CellBounds.Width * z, e.CellBounds.Height);                                RectangleF rect2 = new RectangleF(rect1.Right, e.CellBounds.Top, e.CellBounds.Width * z2, e.CellBounds.Height);                                e.Graphics.DrawString(text, this.dataGridView1.Font, Brushes.Red, rect1, sf);                                e.Graphics.DrawString(text2, this.dataGridView1.Font, Brushes.Red, rect2, sf);                                break;                            default:                                 e.Graphics.DrawString(text, this.dataGridView1.Font, Brushes.Red, e.CellBounds, sf);                                break;                         }                     }                    e.Handled = true;                }            }        }

        在CellMouseClick 事件对动作进行处理。

                

        private void dataGridView1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)        {            Point pt = e.Location;            if (e.ColumnIndex >= 0 && e.RowIndex >= 0)            {                if (this.dataGridView1.Columns[e.ColumnIndex].HeaderText == "Op")                {                    Employee model = this.dataGridView1.Rows[e.RowIndex].DataBoundItem as Employee;                    if (model != null)                    {                        int md = model.Age % 3;                        string text = "删除";                        if (model.Age % 3 == 1)                        {                            text = "修改";                        }                        switch (md)                        {                            case 1:                                                           break;                            case 2:                                string text2 = "删除";                                if (model.Age % 3 == 2)                                {                                    text2 = "修改";                                }                                Graphics g = this.dataGridView1.CreateGraphics();                                SizeF size = g.MeasureString(text, this.dataGridView1.Font);                                SizeF size2 = g.MeasureString(text2, this.dataGridView1.Font);                                float z = size.Width / (size.Width + size2.Width);                                float z2 = size2.Width / (size.Width + size2.Width);                                Rectangle rect = new Rectangle(0, 0, this.dataGridView1.Columns[e.ColumnIndex].Width, this.dataGridView1.Rows[e.RowIndex].Height);                                RectangleF rect1 = new RectangleF(rect.Left, rect.Top, rect.Width * z, rect.Height);                                RectangleF rect2 = new RectangleF(rect1.Right, rect.Top, rect.Width * z2, rect.Height);                                if (rect1.Contains(pt))                                {                                    MessageBox.Show("1111111");                                }                                if (rect2.Contains(pt))                                {                                    MessageBox.Show("2222222");                                }                                break;                            default:                                          break;                        }                     }                }            }                    }
