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);

　//定义列宽this.dataGridView1.Columns[0].Width = 80;

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

　Customize Cells and Columns in the Windows Forms DataGridView Control by Extending Their

　Behavior and Appearance

　Host 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。

　Programmatically Resize Cells to Fit Content in the Windows Forms DataGridView Control

　Samples：

　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);

　Change the Border and Gridline Styles in the Windows Forms DataGridView Control

　Samples:

　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;

　Samples：

　customersDataGridView.Columns["CustomerID"].Visible = false;

　customersDataGridView.Columns["ContactName"].DisplayIndex = 0;

　customersDataGridView.Columns["ContactTitle"].DisplayIndex = 1;

　customersDataGridView.Columns["City"].DisplayIndex = 2;

　customersDataGridView.Columns["Country"].DisplayIndex = 3;

　customersDataGridView.Columns["CompanyName"].DisplayIndex = 4;

　Display Images in Cells of the Windows Forms DataGridView Control

　Samples：

　Icon treeIcon = new Icon(this.GetType(), "tree.ico");

　DataGridViewImageColumn iconColumn = new DataGridViewImageColumn ();

　iconColumn.Image = treeIcon.ToBitmap();

　iconColumn.Name = "Tree";

　iconColumn.HeaderText = "Nice tree";

　dataGridView1.Columns.Insert(2, iconColumn);

　Format Data in the Windows Forms DataGridView Control

　Samples:

　this.dataGridView1.Columns["UnitPrice"].DefaultCellStyle.Format = "c";

　this.dataGridView1.Columns["ShipDate"].DefaultCellStyle.Format = "d";

　this.dataGridView1.DefaultCellStyle.NullValue = "no entry";

　this.dataGridView1.DefaultCellStyle.WrapMode = DataGridViewWrapMode.Wrap;

　this.dataGridView1.Columns["CustomerName"].DefaultCellStyle.Alignment =

　DataGridViewContentAlignment.MiddleRight;

　Freeze Columns in the Windows Forms DataGridView Control

　Samples：将指定列及以前的列固定不动

　this.dataGridView1.Columns["AddToCartButton"].Frozen = true;

　Get the Selected Cells, Rows, and Columns in the Windows Forms DataGridView Control

　Samples:

　Handle Errors that Occur During Data Entry in the Windows Forms DataGridView Control

　Samples：

　private void dataGridView1_DataError(object sender,

　DataGridViewDataErrorEventArgs e)

　{

　// If the data source raises an exception when a cell value is

　// commited, display an error message.

　if (e.Exception != null &&

　e.Context == DataGridViewDataErrorContext.Commit)

　{

　MessageBox.Show("CustomerID value must be unique.");

　}}

　Make Columns in the Windows Forms DataGridView Control Read-Only

　Samples：

　dataGridView1.Columns["CompanyName"].ReadOnly = true;

　Remove Autogenerated Columns from a Windows Forms DataGridView Control

　Sample:

　dataGridView1.AutoGenerateColumns = true;

　dataGridView1.DataSource = customerDataSet;

　dataGridView1.Columns.Remove ("Fax");

　或：

　dataGridView1.Columns["CustomerID"].Visible = false;
