这篇文章主要为大家展示了"C#中对DatagridView的常用操作有哪些"，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下"C#中对DatagridView的常用操作有哪些"这篇文章吧。

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 TheirBehavior and AppearanceHost 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 ControlSamples：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

Bind Objects to Windows Forms DataGridView Controls

4、可以改变表格线条风格

Change the Border and Gridline Styles in the Windows Forms DataGridView ControlSamples: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

Change the Order of the Columns in the Windows Forms DataGridView ControlSamples：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

Display Images in Cells of the Windows Forms DataGridView ControlSamples：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:

Format Data in the Windows Forms DataGridView ControlSamples: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、在拖动列的滚动条时可以将指定的列冻结

Freeze Columns in the Windows Forms DataGridView ControlSamples：将指定列及以前的列固定不动this.dataGridView1.Columns["AddToCartButton"].Frozen = true;

9、获取选择的单元格,行,列

Get the Selected Cells, Rows, and Columns in the Windows Forms DataGridView ControlSamples:

10、显示录入时出现的错误信息

Handle Errors that Occur During Data Entry in the Windows Forms DataGridView ControlSamples：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、大数据量显示采用Virtual Mode

Implement Virtual Mode in the Windows Forms DataGridView Control

12、设置指定的列只读

Make Columns in the Windows Forms DataGridView Control Read-OnlySamples：dataGridView1.Columns["CompanyName"].ReadOnly = true;

13、移去自动生成的列

Remove Autogenerated Columns from a Windows Forms DataGridView ControlSample:dataGridView1.AutoGenerateColumns = true;dataGridView1.DataSource = customerDataSet;dataGridView1.Columns.Remove ("Fax");或：dataGridView1.Columns["CustomerID"].Visible = false;

14、自定义选择模式

Set the Selection Mode of the Windows Forms DataGridView ControlSample：this.dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;this.dataGridView1.MultiSelect = false;

15、自定义设定光标进入单元格是否编辑模式（编辑模式）

Specify the Edit Mode for the Windows Forms DataGridView Controlthis.dataGridView1.EditMode = DataGridViewEditMode.EditOnEnter;

16、新行指定默认值

Specify Default Values for New Rows in the Windows Forms DataGridView ControlSample：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、数据验证

Validate Data in the Windows Forms DataGridView ControlSamples：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;}}}

18、数据提交到dataset中

DataSet ds = new DataSet("MyDataSet");ds.Tables[biaom.Trim()].Rows.Clear();try{for (int i = 0; i < dataGridView1.Rows.Count - 1; i++){DataTable dt = ds.Tables[biaom.Trim()];DataRow myrow = ds.Tables[biaom.Trim()].NewRow();for (int j = 0; j < dataGridView1.Columns.Count; j++){myrow[j] = Convert.ToString(dataGridView1.Rows[i].Cells[j].Value);}ds.Tables[biaom.Trim()].Rows.Add(myrow);}}catch (Exception){MessageBox.Show("输入类型错误！");return;}
