C#中对DatagridView的部分常用操作2011-08-10C#中对DatagridView部分常用操作

只列出技巧部分,后面会有补充

0（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 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。

2、自动适应列宽

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）;
