Populate multiple datagridviews from a 2 dimensional array

C#

I have a 2 dimensional array: myGridData[49,5].
The data was collected from 7 datagridviews, each with 7 rows x 5 columns.
I want to re-populate the 7 datagridviews with the data back from the array.

I have tried this:

var rowCount = myGridData.GetLength(0);
var rowLength = myGridData.GetLength(1);

var dgvs = new[] { dgv6, dgv5, dgv4, dgv3, dgv2, dgv1, dgv0, };

dgvs[0].ColumnCount = 5;
dgvs[1].ColumnCount = 5;
dgvs[2].ColumnCount = 5;
dgvs[3].ColumnCount = 5;
dgvs[4].ColumnCount = 5;
dgvs[5].ColumnCount = 5;
dgvs[6].ColumnCount = 5;

for (int rowIndex = 0; rowIndex < rowCount - 1; ++rowIndex)
{
    for (int x=0;x<7;x++)   //grids
    {
        var row = new DataGridViewRow();

            for (int columnIndex = 0; columnIndex < rowLength; ++columnIndex)
            {
                    row.Cells.Add(new DataGridViewTextBoxCell()
                    {
                            Value = myGridData[rowIndex, columnIndex]
                    });
            }
        dgvs[x].Rows.Add(row);

    }
}

but what I get back is 49 rows in each grid with incorrect data.
Any help would be appreciated.
