如何以编程方式向datagridview添加新行

如果将行添加到 DataTable

DataRow row = datatable1.NewRow();
row["column2"]="column2";
row["column6"]="column6";
datatable1.Rows.Add(row);

怎么样DataGridView??

你可以做：

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells[0].Value = "XYZ";
row.Cells[1].Value = 50.2;
yourDataGridView.Rows.Add(row);

要么：

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells["Column2"].Value = "XYZ";
row.Cells["Column6"].Value = 50.2;
yourDataGridView.Rows.Add(row);

其他方式：

this.dataGridView1.Rows.Add("five", "six", "seven","eight");
this.dataGridView1.Rows.Insert(0, "one", "two", "three", "four");

来自：http : //msdn.microsoft.com/zh-cn/library/system.windows.forms.datagridview.rows.aspx

像这样：

var index = dgv.Rows.Add();
dgv.Rows[index].Cells["Column1"].Value = "Column1";
dgv.Rows[index].Cells["Column2"].Value = 5.6;
//....

假设您有一个未绑定到数据集的datagridview，并且您想以编程方式填充新行...

这是您的操作方式。

// Create a new row first as it will include the columns you've created at design-time.

int rowId = dataGridView1.Rows.Add();

// Grab the new row!
DataGridViewRow row = dataGridView1.Rows[rowId];

// Add the data
row.Cells["Column1"].Value = "Value1";
row.Cells["Column2"].Value = "Value2";

// And that's it! Quick and painless... :o)

像这样：

 dataGridView1.Columns[0].Name = "column2";
 dataGridView1.Columns[1].Name = "column6";

 string[] row1 = new string[] { "column2 value", "column6 value" };
 dataGridView1.Rows.Add(row1);

或者您需要使用property分别设置那里的值.Rows()，像这样：

 dataGridView1.Rows[1].Cells[0].Value = "cell value";

使用Add（）在没有行的DGV中添加新行会引发SelectionChanged事件，然后才能插入任何数据（或在Tag属性中绑定对象）。

从RowTemplate创建克隆行更安全：

//assuming that you created columns (via code or designer) in myDGV
DataGridViewRow row = (DataGridViewRow) myDGV.RowTemplate.Clone();
row.CreateCells(myDGV, "cell1", "cell2", "cell3");

myDGV.Rows.Add(row);

如果dgrview为空，这就是我添加一行的方式：（myDataGridView在示例中有两列）

DataGridViewRow row = new DataGridViewRow();
row.CreateCells(myDataGridView);

row.Cells[0].Value = "some value";
row.Cells[1].Value = "next columns value";

myDataGridView.Rows.Add(row);

根据docs：“ CreateCells（）清除现有单元并根据提供的DataGridView模板设置其模板”。

如果网格绑定到数据集/表，最好使用BindingSource

var bindingSource = new BindingSource();
bindingSource.DataSource = dataTable;
grid.DataSource = bindingSource;

//Add data to dataTable and then call

bindingSource.ResetBindings(false)    

这是这样做的另一种方法

 private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        dataGridView1.ColumnCount = 3;

        dataGridView1.Columns[0].Name = "Name";
        dataGridView1.Columns[1].Name = "Age";
        dataGridView1.Columns[2].Name = "City";

        dataGridView1.Rows.Add("kathir", "25", "salem");
        dataGridView1.Rows.Add("vino", "24", "attur");
        dataGridView1.Rows.Add("maruthi", "26", "dharmapuri");
        dataGridView1.Rows.Add("arun", "27", "chennai"); 
    }

如果您需要操作除“单元格值”字符串之外的任何操作（例如添加标签），请尝试以下操作：

DataGridViewRow newRow = (DataGridViewRow)mappingDataGridView.RowTemplate.Clone();
newRow.CreateCells(mappingDataGridView);

newRow.Cells[0].Value = mapping.Key;
newRow.Cells[1].Value = ((BusinessObject)mapping.Value).Name;
newRow.Cells[1].Tag = mapping.Value;

mappingDataGridView.Rows.Add(newRow);

yourDGV.Rows.Add(column1,column2...columnx); //add a row to a dataGridview
yourDGV.Rows[rowindex].Cells[Cell/Columnindex].value = yourvalue; //edit the value

您还可以创建一个新行，然后将其添加到DataGridView中，如下所示：

DataGridViewRow row = new DataGridViewRow();
row.Cells[Cell/Columnindex].Value = yourvalue;
yourDGV.Rows.Add(row);

如果要绑定列表

List<Student> student = new List<Student>();

dataGridView1.DataSource = student.ToList();
student .Add(new Student());

//Reset the Datasource
dataGridView1.DataSource = null;
dataGridView1.DataSource = student;

如果绑定数据表

DataTable table = new DataTable();

 DataRow newRow = table.NewRow();

// Add the row to the rows collection.
table.Rows.Add(newRow);

从dataGridView复制行的示例，并在同一dataGridView中添加了新行：

DataTable Dt = new DataTable();
Dt.Columns.Add("Column1");
Dt.Columns.Add("Column2");

DataRow dr = Dt.NewRow();
DataGridViewRow dgvR = (DataGridViewRow)dataGridView1.CurrentRow;
dr[0] = dgvR.Cells[0].Value; 
dr[1] = dgvR.Cells[1].Value;              

Dt.Rows.Add(dR);
dataGridView1.DataSource = Dt;

//Add a list of BBDD
var item = myEntities.getList().ToList();
//Insert a new object of type in a position of the list       
item.Insert(0,(new Model.getList_Result { id = 0, name = "Coca Cola" }));

//List assigned to DataGridView
dgList.DataSource = item; 

//header
dataGridView1.RowCount = 50;
dataGridView1.Rows[0].HeaderCell.Value = "Product_ID0";


//add row by cell 
 dataGridView1.Rows[1].Cells[0].Value = "cell value";

如果......你已定义的DataSource，你可以得到DataGridView的DataSource，并投它作为一个Datatable。

然后添加一个新的DataRow并设置字段值。

将新行添加到DataTable并接受更改。

在C＃中将是这样。

DataTable dataTable = (DataTable)dataGridView.DataSource;
DataRow drToAdd = dataTable.NewRow();

drToAdd["Field1"] = "Value1";
drToAdd["Field2"] = "Value2";

dataTable.Rows.Add(drToAdd);
dataTable.AcceptChanges();

考虑一个Windows应用程序，并使用Button Click Event将此代码放入其中。

dataGridView1.Rows
                .Add(new object[] { textBox1.Text, textBox2.Text, textBox3.Text });

string[] splited = t.Split('>');
int index = dgv_customers.Rows.Add(new DataGridViewRow());
dgv_customers.Rows[index].Cells["cust_id"].Value=splited.WhichIsType("id;");

但是请注意，这WhichIsType是我创建的扩展方法。
