学习DataGridViewX

列头设置: Columns 集合， name, ColumnType,DataPropertyName. Shape可以选(ButtonXColum)

行字体样式：DefaultCellStyle

行高，复制设置:  RowTemplate

DataGridViewButtonXColumn -- 带有按钮的列，可以在form初始化时候设置按钮的样式:

1.获取按钮

  DataGridViewButtonXColumn bcx =  dataGridViewX1.Columns["Country"] as DataGridViewButtonXColumn;

2. 设置自定义按钮文本

   bcx.UseColumnTextForButtonValue = false;

3. 设置自定义按钮图片（paintCell事件前， 重绘也是逐行绘制，所以bcx.Text得到是该列某一个cell的值）

   bcx.BeforeCellPaint +=X1Country_BeforeCellPaint;

       void X1Country_BeforeCellPaint(object sender, BeforeCellPaintEventArgs e)

        {

            DataGridViewButtonXColumn bcx = sender as DataGridViewButtonXColumn;

            // Set the button flag image to correspond to country

            if (bcx != null)

                bcx.Image = imageList1.Images[bcx.Text];

        }

DataGridView点击事件： CellContentClick

 dataGridViewX1.CellContentClick += DataGridViewX1_CellContentClick;

 void DataGridViewX1_CellContentClick(object sender, DataGridViewCellEventArgs e)

        {

        // 把列转换为DataGridViewButtonXCell, 如果列类型本身不是DataGridViewXColumn，则cell值为null

            DataGridViewButtonXCell cell = dataGridViewX1.CurrentCell as DataGridViewButtonXCell;

            if (cell != null)

            {

// 根据Cell得到列对象ButtonXColumn

                DataGridViewButtonXColumn bc =

                    dataGridViewX1.Columns[e.ColumnIndex] as DataGridViewButtonXColumn;

                if (bc != null)

                {

                    string s = Convert.ToString(cell.Value);

//得到列名字

                    switch (bc.Name)

                    {

                        case "Country":

                            MessageBox.Show("What a great country " + s + " is!", "",

                                            MessageBoxButtons.OK, MessageBoxIcon.Information);

                            break;

                        case "Region":

                            cell.Value = string.IsNullOrEmpty(s) ? "Global" : "";

                            break;

                    }

                }

            }
        }

            // Update the entire column so that each column cell

                // will be reformatted according to the new list values.

重绘列表的方法

                dataGridViewX1.InvalidateColumn(cell.ColumnIndex);
