如何以编程方式向datagridview添加新行

Question

如果添加行 DataTable

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

怎么样DataGridView？

Answer 1

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");

Answer 2

像这样:

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

Answer 3

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

这是你如何做到的.

// 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)

Answer 4

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);

或者您需要单独设置值,使用属性.Rows(),如下所示:

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

Answer 5

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创建一个克隆行是更安全的imho:

//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);

Answer 6

如果dgrview为空,这就是我添加行的方式:( myDataGridView在我的示例中有两列)

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

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

myDataGridView.Rows.Add(row);

根据文档:"CreateCells()清除现有单元格并根据提供的DataGridView模板设置其模板".

Answer 7

如果网格绑定到DataSet /表,最好使用类似BindingSource

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

//Add data to dataTable and then call

bindingSource.ResetBindings(false)    

Answer 8

这是另一种方法来做到这一点

 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"); 
    }

Answer 9

如果您需要操作除 Cell Value 字符串之外的任何内容，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);

Answer 10

如果你正在绑定一个 List

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

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

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

如果您正在绑定 DataTable

DataTable table = new DataTable();

 DataRow newRow = table.NewRow();

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