C# – Set columns width in a datagrid using Compact Framework

I'm trying to set the width of the columns in my datagrid. I use Compact Framework 2.0 and C#

I tried this but it gives me an "out of bonds" error message:

foreach (DataGridColumnStyle vColumnStyle in dataGrid1.TableStyles[0].GridColumnStyles)
{
    vColumnStyle.Width = 100;
}

Here is the code for filling my datagrid with the datatable (only fails when I try to set the columns width):

void FillData()
{
    // 1
    // Open connection
    string conString = "Data Source=\\Program Files\\smartdeviceproject2\\repartocrack.sdf";
    using (SqlCeConnection c = new SqlCeConnection(conString))
    {
        c.Open();
        // 2
        // Create new DataAdapter
        using (SqlCeDataAdapter a = new SqlCeDataAdapter(
        "SELECT codbultocomp, nombre, estado FROM envios INNER JOIN tiendas ON envios.codigodestino = tiendas.codigodestino", c))
        {
            // 3
            // Use DataAdapter to fill DataTable
            DataTable t = new DataTable();
            a.Fill(t);
            // 4
            // Render data onto the screen
            foreach (DataGridColumnStyle vColumnStyle in dataGrid1.TableStyles[0].GridColumnStyles)
            {
                vColumnStyle.Width = 100;
            }
            dataGrid1.DataSource = t;
        }
    }
}
