(最基本的技巧)、获取某列中的某行(某单元格)中的内容
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 in the Windows Forms DataGridView ControlSamples：
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;
6、可以在列中显示图像
Display Images in Cells of the Windows Forms DataGridView ControlSamples：
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);
7、格式化显示内容:
Format Data in the Windows Forms DataGridView ControlSamples:
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;
8、在拖动列的滚动条时可以将指定的列冻结
Freeze Columns in the Windows Forms DataGridView ControlSamples：
将指定列及以前的列固定不动this.dataGridView1.Columns["AddToCartButton"].
Frozen = true;
9、获取选择的单元格,行,列
Get the Selected Cells, Rows,
and Columns in the Windows Forms DataGridView ControlSamples:
10、显示录入时出现的错误信息
Handle Errors that Occur During Data Entry in the Windows
Forms DataGridView ControlSamples：
private void dataGridView1_DataError
(object sender,DataGridViewDataErrorEventArgs e){
// If the
