1、自定義列 Customize Cells and Columns in the Windows Forms DataGridView Control by Extending Their Behavior and Appearance Host Controls in Windows Forms DataGridView Cells 繼承 DataGridViewTextBoxCell 類生成新的Cell類，然后再繼承 DataGridViewColumn 生成新的Column類，并指定 CellTemplate為新的Cell類。新生成的Column便可以增加到DataGridView中去。 2、自動適應(yīng)列寬 ??? 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、可以綁定并顯示對象 ??? Bind Objects to Windows Forms DataGridView Controls 4、可以改變表格線條風(fēng)格 ??? 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、動態(tài)改變列是否顯示，和動態(tài)改變列的顯示順序 ??? 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、可以在列中顯示圖像 ??? 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、格式化顯示內(nèi)容: ??? 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; 8、在拖動列的滾動條時可以將指定的列凍結(jié) ??? Freeze Columns in the Windows Forms DataGridView Control Samples：將指定列及以前的列固定不動 this.dataGridView1.Columns["AddToCartButton"].Frozen = true; 9、獲取選擇的單元格,行,列 ??? Get the Selected Cells, Rows, and Columns in the Windows Forms DataGridView Control Samples: 見msdn。 10、顯示錄入時出現(xiàn)的錯誤信息 ??? 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."); } } 11、大數(shù)據(jù)量顯示采用Virtual Mode Implement Virtual Mode in the Windows Forms DataGridView Control 12、設(shè)置指定的列只讀 ??? Make Columns in the Windows Forms DataGridView Control Read-Only Samples： dataGridView1.Columns["CompanyName"].ReadOnly = true; ? 13、移去自動生成的列 ??? 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; 14、自定義選擇模式 ??? Set the Selection Mode of the Windows Forms DataGridView Control Sample： this.dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect; this.dataGridView1.MultiSelect = false; 15、自定義設(shè)定光標(biāo)進入單元格是否編輯模式（編輯模式） Specify the Edit Mode for the Windows Forms DataGridView Control this.dataGridView1.EditMode = DataGridViewEditMode.EditOnEnter; 16、新行指定默認(rèn)值 ??? Specify Default Values for New Rows in the Windows Forms DataGridView Control Sample： private void dataGridView1_DefaultValuesNeeded(object sender, ?????????????? ???????System.Windows.Forms.DataGridViewRowEventArgs e) { e.Row.Cells["Region"].Value = "WA"; e.Row.Cells["City"].Value = "Redmond"; e.Row.Cells["PostalCode"].Value = "98052-6399"; e.Row.Cells["Region"].Value = "NA"; e.Row.Cells["Country"].Value = "USA"; e.Row.Cells["CustomerID"].Value = NewCustomerId(); } 17、數(shù)據(jù)驗證 ??? Validate Data in the Windows Forms DataGridView Control Samples： private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e) { // Validate the CompanyName entry by disallowing empty strings. if (dataGridView1.Columns[e.ColumnIndex].Name == "CompanyName") { if (e.FormattedValue.ToString() == String.Empty) { dataGridView1.Rows[e.RowIndex].ErrorText = "Company Name must not be empty"; e.Cancel = true; } } }
