protected void chkRow_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox chkrow = (CheckBox)sender;
        
        
            GridViewRow row = (GridViewRow)chkrow.NamingContainer;
            string _facil = string.Empty;
            string _exportDate = DateTime.Now.ToString("MM/dd/yyyy");
            if (_exportDate.Contains('-'))
                _exportDate = _exportDate.Replace('-', '/');

            if (ddlfacility.SelectedIndex > 0)
                _facil = ddlfacility.SelectedValue;

            if (ViewState["selectedRowsFromGrid"] == null)
            {
                System.Data.DataTable dtDynamic = new System.Data.DataTable();

                dtDynamic.Columns.Add("MRN", typeof(string));
                dtDynamic.Columns.Add("Patient Name", typeof(string));
                dtDynamic.Columns.Add("Surgeon", typeof(string));
                dtDynamic.Columns.Add("Procedure", typeof(string));
                dtDynamic.Columns.Add("Export Date", typeof(string));
                dtDynamic.Columns.Add("DOS", typeof(string));
                dtDynamic.Columns.Add("Sex", typeof(string));
                dtDynamic.Columns.Add("Home Phone", typeof(string));
                dtDynamic.Columns.Add("Facility", typeof(string));
                dtDynamic.Columns.Add("Return", typeof(string));
                
                    dtDynamic.Rows.Add(row.Cells[1].Text, row.Cells[2].Text, row.Cells[5].Text, row.Cells[3].Text, _exportDate, row.Cells[7].Text, "", "", _facil, "");
                    dtDynamic.Rows.Add("Notes:____ ");
                    dtDynamic.Rows.Add("");
                    ViewState["selectedRowsFromGrid"] = dtDynamic;
                

            }
            else
            {
                System.Data.DataTable dtDynamic = (System.Data.DataTable)ViewState["selectedRowsFromGrid"];
                dtDynamic.Rows.Add(row.Cells[1].Text, row.Cells[2].Text, row.Cells[5].Text, row.Cells[3].Text, _exportDate, row.Cells[7].Text, "", "", _facil, "");
                dtDynamic.Rows.Add("Notes:____ ");
                dtDynamic.Rows.Add("");
                ViewState["selectedRowsFromGrid"] = dtDynamic;
            }
        
    }

I have this code which inserts a record in a dynamic table when a row is checked in a grid view.  How can I remove the row from the dynamic table when the check box is unchecked?
