Answer 1

Like this:

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

Answer 2

Consider a Windows Application and using Button Click Event put this code in it.

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

Answer 3

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

But be aware, WhichIsType is the extension method I created.

Answer 4

If the grid is bound against a DataSet / table its better to use a BindingSource like

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

//Add data to dataTable and then call

bindingSource.ResetBindings(false)    

Answer 5

If you need to manipulate anything aside from the Cell Value string such as adding a Tag, try this:

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 6

Adding a new row in a DGV with no rows with Add() raises SelectionChanged event before you can insert any data (or bind an object in Tag property).

Create a clone row from RowTemplate is safer 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);
