C#中对DatagridView部分常用操作

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;

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。
