DataGridView新特色、常用操作 列操作 c# dataGridView1.Columns.Insert
1、自定义列 srxljl
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 srxljl
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);
3、可以绑定并显示对象 srxljl
Bind Objects to Windows Forms DataGridView Controls
4、可以改变表格线条风格 srxljl
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;
5、动态改变列是否显示，和动态改变列的显示顺序 srxljl
Change the Order of the Columns in the Windows Forms DataGridView Control
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;
6、可以在列中显示图像 srxljl
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);
7、格式化显示内容: srxljl
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;
续.......
DataGridView.AutoSizeColumns(
DataGridViewAutoSizeColumnCriteria.HeaderAndDisplayedRows);
DataGridView.AutoSizeColumn(
DataGridViewAutoSizeColumnCriteria.HeaderOnly,
2, false);
DataGridView.AutoSizeRow(
