{
DataGridViewRow CurrentRow = poreziDataGridView.SelectedRows[0];
Form2 f1 = new Form2();
f1.idTextBox.Text = poreziDataGridView.CurrentRow.Cells["dataGridViewTextBoxColumn1"].Value.ToString();
f1.imeTextBox.Text = poreziDataGridView.CurrentRow.Cells["dataGridViewTextBoxColumn2"].Value.ToString();
f1.procenatTextBox.Text = poreziDataGridView.CurrentRow.Cells["dataGridViewTextBoxColumn3"].Value.ToString();
f1.fiksna_vrednostTextBox.Text = poreziDataGridView.CurrentRow.Cells["dataGridViewTextBoxColumn4"].Value.ToString();
f1.redni_brojTextBox.Text = poreziDataGridView.CurrentRow.Cells["dataGridViewTextBoxColumn5"].Value.ToString();
f1.ShowDialog();
}

Hello

It seems like you want to transfer all your values of textboxes into form2 , am i right ?

If yes than its easy to implement :

This way you can pass data from form1 to form 2
