Error passing grid view parameters of a form in combo box

Question

Good morning, I have a form where I consult my budgets and in it I own a grid view.

When I double-click on the grid line it opens another form. But I do not see the data that is in the line of my grid view appears the first item of my combo.

This is the event and the code I use to open in the other form. This form is the query:

private void dgvOrc_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
{
    frmOrcDomestico formOrc = new frmOrcDomestico();
    formOrc.PreencheDados(dgvOrc.SelectedRows[0].Cells[0].Value.ToString(),
    dgvOrc.SelectedRows[0].Cells[1].Value.ToString(),
    dgvOrc.SelectedRows[0].Cells[2].Value.ToString(),
    dgvOrc.SelectedRows[0].Cells[3].Value.ToString(),
    dgvOrc.SelectedRows[0].Cells[4].Value.ToString(),
    dgvOrc.SelectedRows[0].Cells[5].Value.ToString(),
    dgvOrc.SelectedRows[0].Cells[6].Value.ToString(),
    dgvOrc.SelectedRows[0].Cells[7].Value.ToString(),
    dgvOrc.SelectedRows[0].Cells[8].Value.ToString());
    formOrc.ShowDialog();
} 

This form is the one that will receive the data from the other.

public void PreencheDados(string id, string c, string p, string t, string dom, string data, string l, string d, string pg)
{
    lblId.Text = id;

    comboCliente.Text = c;

    comboProduto.Text = p;

    comboTipoProduto.Text = t;

    lblDomestico.Text = dom;

    lbld.Text = data;

    lblStatus.Text = l;

    textDescricao.Text = d;

    maskValor.Text = pg;    
}

Since you’re at the event CellContentDoubleClick substitute dgvOrc.SelectedRows[0] for dgvOrc.Rows[e.RowIndex] which is sure to request the value of the clicked line.

    private void dgvOrc_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
    {
       frmOrcDomestico formOrc = new frmOrcDomestico();
       formOrc.PreencheDados(
         dgvOrc.Rows[e.RowIndex].Cells[0].Value.ToString(),
         dgvOrc.Rows[e.RowIndex].Cells[1].Value.ToString(),
         dgvOrc.Rows[e.RowIndex].Cells[2].Value.ToString(),
         dgvOrc.Rows[e.RowIndex].Cells[3].Value.ToString(),
         dgvOrc.Rows[e.RowIndex].Cells[4].Value.ToString(),
         dgvOrc.Rows[e.RowIndex].Cells[5].Value.ToString(),
         dgvOrc.Rows[e.RowIndex].Cells[6].Value.ToString(),
         dgvOrc.Rows[e.RowIndex].Cells[7].Value.ToString(),
         dgvOrc.Rows[e.RowIndex].Cells[8].Value.ToString());
   }

This line may be wrong depending on how the combobox is: comboProduto.Text = p;

Try one of these lines:

comboProduto.SelectedValue = p;

or

comboProduto.SelectedText = p;
