Problems with inserted datagridview checkbox column

Question

I have a few problems with a checkbox column added to a datagridview. The datagridview is bound by a binding source whose datasource is a datatable. I also add in the code a checkbox column:
private
void InitializeDataGridView()
            dgvInvoices.ColumnHeadersDefaultCellStyle.Font =
new Font("Arial", 10,
FontStyle.Bold);
DataGridViewCheckBoxColumn chkColumn =
new DataGridViewCheckBoxColumn();
            chkColumn.FlatStyle =
FlatStyle.Standard;
            dgvInvoices.Columns.Insert(0, chkColumn);
            dgvInvoices.DataSource = bs;
            cmbInvoicingCriteria.Text =
"(All)";
DataGridViewBinding.CreateColumn(dgvInvoices,
"Date", "Date",
DataGridViewContentAlignment.MiddleLeft);
DataGridViewBinding.CreateColumn(dgvInvoices,
"Invoice", "Invoice",
DataGridViewContentAlignment.MiddleLeft);
DataGridViewBinding.CreateColumn(dgvInvoices,
"Customer", "Customer");
DataGridViewBinding.CreateColumn(dgvInvoices,
"Name", "Name");
DataGridViewBinding.CreateColumn(dgvInvoices,
"Count", "Count");
DataGridViewBinding.CreateColumn(dgvInvoices,
"Total", "Total");
DataGridViewBinding.CreateColumn(dgvInvoices,
"Driver", "Driver");
DataGridViewBinding.CreateColumn(dgvInvoices,
"Status", "Status");
DataGridViewBinding.CreateColumn(dgvInvoices,
"ARHID", "ARHID");
DataGridViewBinding.CreateColumn(dgvInvoices,
"AR", "AR");
            dgvInvoices.Columns["ARHID"].Visible =
false;
            dgvInvoices.Columns["AR"].Visible =
false;
this.dgvInvoices.Columns[0].DefaultCellStyle.Font =
new Font("Arial", 18,
FontStyle.Bold);
this.dgvInvoices.Columns["Date"].DefaultCellStyle.Font =
new Font("Arial", 10,
FontStyle.Bold);
this.dgvInvoices.Columns[2].DefaultCellStyle.Font =
new Font("Arial", 10,
FontStyle.Bold);
this.dgvInvoices.Columns["Customer"].DefaultCellStyle.Font =
new Font("Arial", 10,
FontStyle.Bold);
this.dgvInvoices.Columns["Name"].DefaultCellStyle.Font =
new Font("Arial", 10,
FontStyle.Bold);
this.dgvInvoices.Columns["Count"].DefaultCellStyle.Font =
new Font("Arial", 10,
FontStyle.Bold);
foreach (DataGridViewColumn dc
in dgvInvoices.Columns)
                dc.ReadOnly =
true;
if (dc.HeaderText.ToLower() ==
"count" || dc.HeaderText.ToLower() ==
"name" || dc.Index == 0)
this.dgvInvoices.Columns[dc.Index].AutoSizeMode =
DataGridViewAutoSizeColumnMode.AllCellsExceptHeader;
else
this.dgvInvoices.Columns[dc.Index].AutoSizeMode =
DataGridViewAutoSizeColumnMode.Fill;
            dgvInvoices.DefaultCellStyle.Alignment =
DataGridViewContentAlignment.MiddleCenter;
            dgvInvoices.Columns[0].ReadOnly =
false;
            dgvInvoices.Columns[0].Width = 25;
            dgvInvoices.Columns[0].SortMode =
DataGridViewColumnSortMode.Automatic;
The problems I have here are
1. The first checkbox doesn't check off (it used to work when the width was 25 but then I added the code ontop to make the autosize mode of this columns to allcellscellsexcept header it stopped working. I need that though because if I don't make the autosizemode
= all cells except header then when I make the form narrow the checkbox column disappears.) I was wondering why this is happening, and how to fix it.
2. Also this column is not sortable. I added to my code  dgvInvoices.Columns[0].SortMode = DataGridViewColumnSortMode.Automatic;
but it doesn't seem to work.
3. Whenever I sort another column the checked off checkboxes lose their focus. I understand that can be a problem with a bound datagridview and one unbound column, but how can I fix it?

Answer 1

I loaded the data for all the rows from a datatable on the form. The checkbox column is that connected to that bound data. it's just there and I need to be able to tell if each row was checked or not, and I need to be able to sort the checkbox column. I
also need to be able to sort all the other columns without losing the check. The only thing commenting out the foreach would help would be that the first checkbox can be checked, but I want it to be autosizemode = allcellsexceptheader and I want to understand
why it's not working like this. Would you have any ideas? Below is how I bound the datagridview for all columns except the checkbox column.
        private
void LoadDataGridView()
DataGridViewBinding.BindWithData(false, dsInvoicingFilter.Tables[0], dgvInvoices, lblEntryCount, bs);
if (dsInvoicingFilter.Tables[0].Rows.Count == 0)
                btnDelete.Enabled =
false;
                btnOpenInvoice.Enabled =
false;
                btnPrint.Enabled =
false;
                btnSaveAsInvoice.Enabled =
false;
                btnVoid.Enabled =
false;
                btnShip.Enabled =
false;
else
                btnDelete.Enabled =
true;
                btnOpenInvoice.Enabled =
true;
                btnPrint.Enabled =
true;
                btnSaveAsInvoice.Enabled =
true;
                btnVoid.Enabled =
true;
                btnShip.Enabled =
true;
                bs.Position = 0;
            dgvInvoices.Columns[0].Width = 25;
            txtSearch.Text =
public static
void BindWithData(bool autoGenerateColumns,
DataTable datatable,
DataGridView datagridview, Label lblDGVEntryCount,
BindingSource bs)
            datagridview.AutoGenerateColumns = autoGenerateColumns;
            bs.DataSource = datatable;
            datagridview.DataSource = bs;
            DataGridViewEntryCount(datagridview, lblDGVEntryCount);
//ExpandColumns(datagridview);//to do it slows it down. Why can't the dgv remember to do it from when initialized it?
