this.currentposition = this.dataGridView1.BindingContext

[this.dataGridView1.DataSource, this.dataGridView1.DataMember].Position;

bookContent = this.database.dataSet.Tables[0].Rows

[this.currentposition][21].ToString().Trim();

MessageBox.Show(bookContent);

1、自定义列

//定义列宽

this.dataGridView1.Columns[0].Width = 80;

this.dataGridView1.Columns[1].Width = 80;

this.dataGridView1.Columns[2].Width = 180;

this.dataGridView1.Columns[3].Width = 120;

this.dataGridView1.Columns[4].Width = 120;

Customize Cells and Columns in the Windows Forms

DataGridView Control by Extending TheirBehavior and

AppearanceHost Controls in Windows Forms DataGridView Cells

继承 DataGridViewTextBoxCell 类生成新的Cell类，然后再继承 DataGridViewColumn 生成新的Column类，并指定

CellTemplate为新的Cell类。新生成的Column便可以增加到DataGridView中去。

2、自动适应列宽

Programmatically Resize Cells to Fit Content in

the Windows Forms DataGridView ControlSamples：

DataGridView.AutoSizeColumns(DataGridViewAutoSizeColumnCriteria.HeaderAndDisplayedRows);

DataGridView.AutoSizeColumn(DataGridViewAutoSizeColumnCriteria.HeaderOnly,2, false);

DataGridView.AutoSizeRow(DataGridViewAutoSizeRowCriteria.Columns,2, false);

DataGridView.AutoSizeRows

(DataGridViewAutoSizeRowCriteria.HeaderAndColumns,0, dataGridView1.Rows.Count, false);

3、可以绑定并显示对象

Bind Objects to Windows Forms DataGridView Controls

4、可以改变表格线条风格

Change the Border and Gridline Styles in

the Windows Forms DataGridView ControlSamples:

this.dataGridView1.GridColor = Color.BlueViolet;

this.dataGridView1.BorderStyle = BorderStyle.Fixed3D;

this.dataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None;

this.dataGridView1.RowHeadersBorderStyle = DataGridViewHeaderBorderStyle.Single;

this.dataGridView1.ColumnHeadersBorderStyle = DataGridViewHeaderBorderStyle.Single;

5、动态改变列是否显示，和动态改变列的显示顺序

Change the Order of the Columns
