Is it possible to programmatically add a row to a GridView in C# ASP?

I want to add static data directly from the code, not from an array nor an datasource
我想直接从代码中添加静态数据，而不是从数组或数据源

DataTable dt = new DataTable();
DataRow dr = dt.NewRow();
dr["Column1"] = string.Empty;
dt.Rows.Add(dr);
You can then bind your GridViewto the DataTable...
然后，您可以将您GridView的DataTable...
gv.DataSource = dt;
gv.DataBind();

I still recommend that you use binding/datasource, but of course you don't have to. The following should do what you want:
我仍然建议您使用绑定/数据源，但您当然不必这样做。以下应该做你想做的：
DataGridViewTextBoxColumn columntype = new DataGridViewTextBoxColumn();
columntype.HeaderText = "Type";
columntype.Width = 80;
dataGridView1.Columns.Add(columntype);

GridViewRowsCollectiondoesn't have .Addmethod, so you can't do it directly to the GridView.
GridViewRowsCollection没有.Add方法，所以你不能直接对 GridView 做。
There're alternatives. For example if you bind it to a DataTable - you can add custom row with data to the DataTable.
有替代品。例如，如果您将其绑定到 DataTable - 您可以将带有数据的自定义行添加到 DataTable。
Another alternative - do it on client by adding a row to rendered HTML Table.
另一种选择 - 通过向呈现的 HTML 表添加一行在客户端上执行此操作。

dataGridView1.Columns[0].Name = "column1";
dataGridView1.Columns[1].Name = "column2";
string[] row1 = new string[] { "column1 value", "column2 value" };
dataGridView1.Rows.Add(row1);

Rows can be inserted on GridView_RowCreated, Like
可以插入行GridView_RowCreated，例如
protected void gvItems_RowCreated(object sender, GridViewRowEventArgs e)
{
GridViewRow NewHeader = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert);
NewHeader.Font.Bold = true;
NewHeader.CssClass = "heading";
//Item#
TableCell NewHeaderCell = new TableCell();
NewHeaderCell.Text = "#";
NewHeaderCell.HorizontalAlign = HorizontalAlign.Left;
NewHeader.Cells.Add(NewHeaderCell);
//Item#
NewHeaderCell = new TableCell();
NewHeaderCell.Text = "Item#";
NewHeaderCell.HorizontalAlign = HorizontalAlign.Left;
NewHeader.Cells.Add(NewHeaderCell);
//Amount
NewHeaderCell = new TableCell();
NewHeaderCell.Text = "Amount";
NewHeaderCell.HorizontalAlign = HorizontalAlign.Right;
NewHeader.Cells.Add(NewHeaderCell);
GridView1.Controls[0].Controls.AddAt(e.Row.RowIndex +
rowIndex, NewHeader);
}
