What is the code for button (print ), to print information from the datagrid view ?

Answer 1

Can you choose the text approach.

This one for one row.
if (dataGridView2[col, ro].Value != null)
theValue = dataGridView2[col, ro].Value.ToString();
else
theValue = "";

This one for all rows.
foreach (DataGridViewRow row in dataGridView1.Rows)
{
var obj = new MyClass()
{
Nachricht = dataGridView1.row.Cells["Value"].Value.ToString(),
Datum = dataGridView1.row.Cells["File"].Value.ToString()
};
llist.Add(obj);
}
