this.currentposition = this.dataGridView1.BindingContext
[this.dataGridView1.DataSource, this.dataGridView1.DataMember].Position;
bookContent = this.data.ember].Position;
bookCont ][21].ToString().Trim();
MessageBox.Show(bookContent);
1、自訂列
//定義列寬
View
= 80;
this.dataGridView1.Columns[1].Width = 80;
this.dataGridView1.Columns[2].Width = 180;
Grids this.dataGridView1.Columns[4].Width = 120;
Customize Cells and Columns in the Windows Forms
DataGrid Control by Extending TheirBehavior and ell 類別產生新的Cell類，然後繼承DataGridViewColumn 產生新的Column類，並指定
CellTemplate為新的Cell類別。新產生的Column便可以增加到DataGridView中去。
2、自動適應列寬
PRogrammatically Resize Cells to Fit Content in
the Windows Forms DataGridView ControlSamples：
the Windows Forms DataGridView.
DataGridView.AutoSizeColumn(DataGridViewAutoSizeColumnCriteria.HeaderOnly,2, false);
DataGridView.AutoSizeRow(DataGridViewAutoSizeRowCriteria.Columns,2, false);
DataGridView.AutoSizeRows
(Data
3、可以綁定並顯示器物件
Bind Objects to Windows Forms DataGridView Controls
4、可變更表格線條風格
Change the Border and Gridline Styles BlueViolet ;
this.dataGridView1.BorderStyle = BorderStyle.Fixed3D;
this.dataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None;
this.dataGridView1.ColumnHeadersBorderStyle = DataGridViewHeaderBorderStyle.Single;
5、動態改變列是否顯示，和動態改變列的顯示順序
Change the Order of the Columns in the Windows Forms DataGridView ControlSamples：
customersData customersDataGridView.Columns["ContactName"].DisplayIndex = 0;
customersDataGridView.Columns["ContactTitle"].DisplayIndex = 1;
customersDataViewView. umns[" Country"].DisplayIndex = 3;
customersDataGridView.Columns["CompanyName"].DisplayIndex = 4;
6、可在欄位中顯示映像Icon treeIcon = new Icon(this.GetType(), "tree.ico");
DataGridViewImageColumn iconColumn = new DataGridViewImageColumn ();
iconColumn.Image = treeI.Toemage ;iconColumn.HeaderText = "Nice tree";
dataGridView1.Columns.Insert(2, iconColumn);
7、格式化顯示內容:
.Columns["UnitPrice"].DefaultCellStyle.Format = "c";
this.dataGridView1.Columns["ShipDate"].DefaultCellStyle.Format = "d";
this.ApryStyle. ";
this.dataGridView1.DefaultCellStyle.WrapMode = DataGridViewWrapMode.Wrap;
this.dataGridView1.Columns["CustomerName"]. 、在拖曳列的滾動條時可以將指定的欄位凍結
Freeze Columns in the Windows Forms DataGridView ControlSamples：
將指定欄位及先前的欄位固定不動this.dataGridView1.Columns["AddToCartButton"].
9、取得選取的儲存格,行,列
Get the Selected Cells, Rows,
and Columns in the Windows Forms DataGridView ControlSamples:
and Columns in the Windows Forms DataGridView ControlSamples:
and Columns in the Windows Forms DataGridView ControlSamples:
Errors that Occur During Data Entry in the Windows
Forms DataGridView ControlSamples：
private void dataGridView1_DataError
(object sender,DataGrid方格DataErrorEventArgs e){
(object sender,DataGrid配置ErrorEventArgs e){
/
////////////////////////////////////////////////////////-付付端行為提交訊息。
if
(e.Exception != null &&e.Context == DataGridViewDataErrorContext.Commit){
MessageBox.Show("CustomerID"); 、大數據量顯示採用虛擬模式
在Windows 窗體DataGridView 控制項中實作虛擬模式
12、設定指定的列互動
在Windows 窗體中製作欄位Data Columns["CompanyName"].ReadOnly = true;
13、移去自動產生的列
從Windows 窗體DataGridView ControlSample 中刪除自動產生的列：
DataSource
= customerDataSet;dataGridView1.Columns.Remove ("Fax 」）；
或：dataGridView1.Columns["CustomerID"].Visible = false
14、自訂Windows Forms DataGridView ControlSample：
this.dataGridView1.SelectionMode
= DataGridViewSelectionMode.FullRowSelect;
this.dataGrids
指定Windows 窗體DataGridView 的編輯模式
Controlthis.dataGridView1.EditMode
= DataGridViewEditMode.EditOnEnter;
16、新行指定private void dataGridView1_DefaultValuesNeeded(object sender,
System.Windows.Forms.DataGridViewRowEventArgs e){
e.Row.Cells["Region"].Value. .Value = "雷蒙";
e.Row.Cells["郵遞區號"].Value = "98052-6399";
e.Row.Cells["Region"].Value = "NA";
e.Row.Cells["國家"].Value = "美國";
e.Row.Cells["CustomerID"].Value = NewCustomerId();
}
17
驗證Windows 窗體DataGridView ControlSamples 中的資料：
private void dataGridView1_CellValidating
(object sender,DataGridViewCellValidatingEventArgs e){
if (dataGridView1.Columns[e.ColumnIndex].Name == "CompanyName"){
if (e.FormattedValue.ToString() == String.Empty){
dataView1.Rowsx]. ErrorText
="公司名稱不能為空";
e.Cancel = true;
}
}
}
Data 18、設定資料集到資料集中);
ds.Tables[biaom.Trim()].Rows.Clear();
try{for (int i = 0; i
DataTable ds.Tables[biaom.Trim()];
DataRow myrow = ds.Tables[biaom.Trim()].NewRow();
for (int j = 0; j
myrow[j] = Convert.ToString(dataGridView1.Rows[i].Cells[j].Value);
}
ds.Tables[biaom.Trim()].Rows.Add(myrow);
}
}
catch（異常）{
MessageBox.Show("輸入類型錯誤！");
